TreeSet, TreeMap or Comparable?
I'm simply tackling this problem concerning a list of employee's and their division # within a company...

Taoubina, Xenia 6They're suppose to be stored in alphabetical order...My thing is, should this be approached using TreeSet, TreeMap or Comparable...From what I understand each one is, both TreeSet and TreeMap are both red/black tree implemenations of a binary search tree and TreeSet stores data with an element and a TreeMap a seperate key is created and stored in the collection while the data is stored somewhere else...Comparable seems to be used by either method considering that they are sorted and put into order in either case...Inputs anyone? I believe the information above is true, but they seem very similiar in characteristic, to me at least...
If you're going to put it into a TreeSet or TreeMap,
either it needs to implement Comparable, or you need
to provide a Comparator.
Implement Comparable if there's a sensible "natural"
way to sort it--e.g. by last name then first, or by
employee ID. Provide a Comparator if you want to sort
by some arbitrary criteria that aren't necessarily a
"natural" way to sort this class--e.g. years of
service.
Whether you use the Set or the Map depends on how you
will access the elements. Will you just iterate over
them sequentially (Set) or will you need to access
them at random by some key (Map)?This list will be sorted by last name only...And yeah, I suppose a lot of the factor using either Set or Map depends on the accessing of elements - In general though, I think that TreeMap would be sufficient because doesn't it provides guaranteed log(n) time cost for the containsKey, find/get, insert and remove/delete operations...

Problem in using TreeSet with a Comparator
Hello,
There seems to be a bug in the implementation of TreeSet, while using a specific Comparator to sort its elements.
Here's the problem I got into: the Comparator I use has a type parameter which defines, of course, the type of objects that may be compared. These objects have an integer field 'value'. In the redefinition of 'compare' method inside the Comparator, if the values are equal, 0 is returned, otherwise returns -1 or 1.
Now, I want to add objects into my TreeSet having this Comparator. But, when I call add for an object that has the field 'value' equal to a value from an object that is already in the Tree Set, it doesn't add it. I red the API documentation, which says that a non-null object o1 is not added into the tree set if there is already an object o2 such that o1.equals(o2) returns true. Or, my objects are far from being equal: the references are different, there are even some fields different.
Nevertheless, all my elements are comparable.
Am I ignoring something or is there a bug?
Thanks.When I call add for an object that has the field 'value' equal to a value from an object that is already in the Tree Set, it doesn't add it.Correct. That's how it is supposed to behave. A Set cannot contain duplicates.
I read the API documentationEvidently not all of it ;-) -
Hi everyone!
I'm trying to implement a Scheduler which insert some Deadline in a TreeSet (sorted by expiration timestamp): another Thread "read" TreeSet in order to remove Deadline expired. For this purpose my Deadline class implements Comparable interface and the its method compareTo in this way:
public int compareTo (Object obj) {
Deadline d = (Deadline) obj;
if (this.deadline > d.deadline)
return 1;
else if (d.deadline > this.deadline)
return -1;
else {
if (this.equals(obj))
return 0;
else
return 1;
}My class Deadline doesn't extends any other class and doesn't re-implements method equals.
Belove part of my "killer" thread which "read" TreeSet:
while (v.size() > 0) {
dl = (Deadline) v.first();
if (dl.deadline <= last) {
v.remove(dl);
ans = dl.deadline;
else {
ans = dl.deadline;
break;
.........In some cases (probably when timestamp deadline of Deadline class is equal to that of another Deadlne) removal of Deadline is not performed: TreeSet method first() give me a Deadline, but then I can't remove it from TreeSet. So TreeSet size is never decremented and I hava an infinite while cicle. Probably the problem is my implementation of method compareTo but I can't understand what is wrong!
Can somenone help me?
Thank you all in advance!
DiegoI want to insert in my TreeSet Deadline with the same timestamp deadline, because this can happen. When timestamp is equal, get/remove method of TreeMap should navigate in its internal tree and search, between all Deadline with the same timestamp, that which satisfy equals check.

Any simple example for comparator for treemap
I have a treemap collection stored some data like
a:4
b:7
c:5
d:7
e:1
f:3
The Treemap helped me to sort by key value like above.
But what I want is sort by value , it should be like this
b:7
d:7
c:5
a:4
f:3
e:1
I know comparator object can help me about the sorting mechanism in treemap, it is used like
comp is comparator
TreeMap tm = new TreeMap(comp)
but I don't know how to construct this comparator object to help me sort by value.
Any one can help me here??
Thank youHere's a sample that demonstrates the issue. Note that when you run this that the comparator class never sees the data items (in this case 'a' - 'f'), only the numbers.
Also notice that both sets that are returned (keySet and entrySet) are appropriately sorted.
Finally, it is interesting to note that it looks like the TreeMap.get() method walks the tree to find the entry (no surprise), but the entrySet method returns both the keys and data in one shot. This implies that there may be a performance blip gained by asking for the entrySet and getting the values that way, rather than the first technique using the keySet and get().
import java.util.*;
public class x
public static void main(String args[])
TreeMap t = new TreeMap(new Comparator() {
public int compare(Object o1, Object o2) {
Comparable c1 = (Comparable) o1;
Comparable c2 = (Comparable) o2;
System.out.println("Comparing " + c1 + " - " + c2);
return c1.compareTo(c2);
public boolean equals(Object o) {
return false;
String s;
t.put("1", "f");
t.put("2", "e");
t.put("3", "d");
t.put("4", "c");
t.put("5", "b");
t.put("6", "a");
Iterator i;
Set keys = t.keySet();
i = keys.iterator();
while(i.hasNext()) {
s = (String)i.next();
System.out.println(s + " - " + t.get(s));
Set entries = t.entrySet();
i = entries.iterator();
while(i.hasNext()) {
System.out.println(i.next()); -
I am trying to implement a schedule using a TreeSet and a Comparator.
The TreeSet constructor receives a Comparator.
Then I start adding objects that implement an Interface called ScehdulableInterface.
All objects that implement this interface have a method:
Public Date getDate()
The Comparator compare method is defined like this:
public int compare(Object o1, Object o2) {
return ((SchedulableInterface)o1).getEndDate().compareTo(((SchedulableInterface)o2).getEndDate());
My problem is the TreeSet is not accepting objects in the same date. Is there any other Collection that accepts the Comparator interface and accepts objects with the same date ?
Thanks.
EliOf course with something like this:public int compare(Object o1, Object o2) {
// checks for null and other error handling omitted...
SchedulableInterface si1 = (SchedulableInterface) o1;
SchedulableInterface si2 = (SchedulableInterface) o2;
int endDateCompare = s1.getEndDate().compareTo(s2.getEndDate();
if (endDateCompare == 0) {
return s1.getSubject().compareTo(s2.getSubject());
} else {
return endDateCompare; -
How to get TreeSet from TreeMap?
Hi,
I tried the following:
(TreeSet)treeMap.keySet()Is there a way to get the treeset from treemap without creating a new instance of treeset and adding all values from this keySet?leden wrote:
Hi,
I tried the following:
(TreeSet)treeMap.keySet()Is there a way to get the treeset from treemap without creating a new instance of treeset and adding all values from this keySet?No, as is quite clear from the docs. TreeMap's keySet() method is only guaranteed to return some Set implementation. If you want a specific implementation, you have to create it. Is that a problem, and if so, why? -
Hi,
I've been trying to work this out and can't seem to find a solution. I have a treemap of object and I want to sort them by their names, such as lastname. These object hold all these datas. I wrote myself a comparator class like this:
import java.util.*;
import java.io.*;
public class PatientComparator implements Comparator {
public int compare(Object obj1, Object obj2) throws ClassCastException {
System.out.println(obj1.getClass()); //use to see what is passing in to compare
Patient a = (Patient)obj1;
Patient b = (Patient)obj2;
String nameA = a.getName();
String nameB = b.getName();
String firstName = nameA.substring(0,nameA.indexOf(",",0)-1);
String lastName = nameA.substring(nameA.indexOf(",",0)+1,nameA.length()-1);
String firstName2 = nameB.substring(0,nameB.indexOf(",",0)-1);
String lastName2 = nameB.substring(nameB.indexOf(",",0)+1,nameB.length()-1);
int result = 0;
if ( !(lastName.equals(lastName2)) )
result = lastName.compareTo(lastName2);
else
result = firstName.compareTo(firstName2);
return result;
I have to use TreeMap or HashMap right now because they both utilize the assigned key to identify object quicker. But the culprit is how do I sort this TreeMap in term of object properties(like name, age). Here is the class I implement it:
public class DoctorsOffice {
private String office_name;
private int ID = 1000; //start out with id # 1000
private SortedMap active = new TreeMap(new PatientComparator());
//private SortedSet inactive = new TreeSet();
* Constructor for a DoctorsOffice object.
* @param name Name of this Dr's Office
public DoctorsOffice (String name) {
office_name = name;
* Add a new patient to the office. The identification
* number is uniquely generated and is returned when the
* Patient object is added to the database. ID numbers
* start at 1000 and increment by one for each new Patient
* added.
* @param firstName first name of this patient
* @param lastName last name of this patient
* @param age age of this patient
* @return the ID number assigned to this Patient
public int addPatient (String firstName, String lastName, int age) {
Patient new_patient = new Patient( firstName,lastName,age );
active.put( new Integer(ID), new_patient );
ID++;
return (ID - 1);
* Remove this patient from the master database. Removed patients are
* archived in an "inactive" database which maintains Patron
* objects in the order in which they were removed from the master
* database.
* @param patientNo Patient number assigned
* @exception throws a NoSuchPatientException
* if this patient does not exist
public void removePatient (int patientNo)
throws NoSuchPatientException {
* Add a new medication for this patient.
* @param patientNo Patient number
* @param medicationName Name of this medication
* @param isGeneric True if a generic drug
* @exception throws NoSuchPatientException if
* this patient ID does not exist.
public void addMedication(int patientNo, String medicationName,
boolean isGeneric ) throws NoSuchPatientException {
if ( active.containsKey(new Integer(patientNo)) ) {
((Patient)active.get(new Integer(patientNo))).recordNewMed(
medicationName, isGeneric );
else
throw new NoSuchPatientException();
* Print the medication detail for this patient. Print
* the patient's full name (lastname COMMA SPACE firstName)
* then each medication (each one on a new line). To print
* the medications, simply call your toString() method in
* the Medication class.
* If this patient has no medication history, print "No Medications
* Prescribed".
* @param patientNo Patient number
* @exception throws NoSuchPatientException
* if patient does not exist.
public void printMedicationDetail (int patientNo)
throws NoSuchPatientException {
Integer patientID = new Integer(patientNo);
if ( active.containsKey(patientID) ) {
System.out.println( ( (Patient)active.get(patientID)).getName() );
((Patient)active.get(patientID)).printMedicationHistory();
else
throw new NoSuchPatientException();
* Print all patients ordered by last name, then first name if
* you encounter two patients with the same last name.
* To print the Patient objects, simply call your toString() method
* in the Patient class.
public void listByName() {
// Collection coll = active.values();
// List temp = new ArrayList(coll);
// sort(temp,new PatientComparator());
// Set s = temp.keySet();
Iterator iterator = active.iterator();
while( iterator.hasNext() ){
// String key = (String)iterator.next();
System.out.println(iterator.next());
}I guess I go with the easiest way to do it. But here's
another culprit, since values() method turn my
TreeMap into a collection(interface), It doesn't turn the TreeMap into anything. That is, the original TM still exists, exactly as you left it. There's just a new Collection created that refers to each of the TM's values.
and the sort()
method is in class Collections, how do I call the
sort(), and also the sort() method has two parameters
(List list, Comparator C)If your values implement Comparable, and you want to use the natural sort order (for instance, the values are Strings and you just want them sorted alphabetically), then you just call the sort method that takes a single List parameter. Otherwise (for instance, you want to reverse the sort order, or sort by length, etc.), you have to write a Comparator for your values.
>
1st) I don't have any list to put as parameter.Both LinkedList and ArrayList take a Collection as a constructor arg, I think, so you can construct one from the Collection returned by values().
2nd) Comparator C will keep comparing two keys from
the treemap or in the collection?
Collection coll = active.values();
Collections.sort( , new
PatientComparator());The TreeMap's Comparator will do that. The values List will sort however you tell it to, regardless of how the TreeMap sorts its keys.
I don't think the sort is able to be called this way,
and what do I substitute in for a parameter list when
I have a treemap right now? Huh? -
So, I'm trying to do something which I thought was fairly simple.
I have a very simple record class who's only members are two strings and then there are the usual set/get methods. Let us call it class Foo.
Now, I want to have a set of Foo's which keeps ordering based on first member, second member (e.g., like lastname, firstname). So, I build FooComparator which implements compare and equals. I then create my set class like this:
public class FooSet extends TreeSet {
public FooSet() {
super(new FooComparator());
}and I get:
FooSet.java:23: warning: [unchecked] unchecked call to TreeSet(java.util.Comparator<? super E>) as a member of the raw type java.util.TreeSet
super(new FooComparator());
FooComparator looks like this:
public class FooComparator implements Comparator, Serializable {
public FooComparator() {
super();
//impl of compare() and equals()
}My two questions are:
1) Is this warning ignorable?
2) If not, what is the correct fix?
Thanks, everyone.
Best,
GlennThe warning isn't a biggie... I'm pretty sure it's because you're not using generics. So lets say your your record class is called FooRecord. If you changed your code around to this, it should be fine.
public class FooSet extends TreeSet<FooRecord> {
public FooSet() {
super(new FooComparator());
}There might be a cleaner way to implement this (I'm not too clear on generics) but I'm pretty sure that'll do the trick. Once you get into generics they're awesome and make things a hell of a lot easier.

com.dset.ncx.session.ConfiguratorBean_m2uo2d_EOImpl.generateScripts(C
onfiguratorBean_m2uo2d_EOImpl.java:487)Thanks for the help abnormal. In my full code I had instantiated TreeSet with a Comparator, but I must have had a problem in the compare() code. I'll have to look into it more closely; as the stack trace did indicate an error in the compare() method in TreeMap. This would also explain why a single object can be added before there is a problem, because a compare wouldn't happen until there is more than one object. One other question: when comparing objects in the compare() method of the Comparator, can I choose any member of the object to compare for ordering or is there some standard I must follow when comparing objects?
Thanks again. -
this method is part of my lab, it should sort words in alphabetical order from
from A to Z . .
i don;t undersatand why did we use .compareTo in this method??
could someone explain what does this method mean
public static void sortList()
String temp;
for(int k = 0; k < count-1; k++)
for(int p = k+1; p < count; p++)
if(list[k].compareTo(list[p]) > 0)
temp = list[k];
list[k] = list[p];
list[p] = temp;
}If all of the elements in a collection implement the Comparable interface, which defines the compareTo method, then the sorting can be done automatically using a TreeSet( ), TreeMap( ), or Collections.sort( ) method. For example:
public class MyClass
implements Comparable
public int compareTo( Object o )
if( equals( o ) ) return 0;
if( o == null ) return -1;
if( !(o instanceof MyClass) ) throw new ClassCastException( );
MyClass that = (MyClass)o;
if( this.getValue( ).lessThan( that.getValue( ) )
return -1;
else
return 1;
public class SomeOtherClass
public void someMethod( )
List myClassList = new ArrayList( );
for( int i = 0; i < 10; i++ ) myClassList.add( new MyClass( ) );
// Sorts myClassList by casting each element to Comparable
// and calling compareTo( )
List sortedList = Collections.sort( myClassList );

JProgressBar Shows Up Too Late--How Do I Update the Display Immediately?
My application has a split pane, the bottom page of which is a panel containing an image that takes a long time to load. For that reason, I want the bottom pane to be a panel with a progress bar until the image is ready.
Here's a simple version of my code:
JPanel progressBarPanel = new JPanel();
JProgressBar progressBar = new JProgressBar(0, 1);
progressBar.setIndeterminate(true);
progressBarPanel.add(progressBar);
splitPane.setBottomComponent(progressBarPanel); // line A
splitPane.invalidate();
JPanel imagePanel = createImagePanelSlowly(); // line B
splitPane.setBottomComponent(imagePanel);
splitPane.invalidate();However, this doesn't work; the display isn't updated until the image is ready. What do I need to put in between lines A and B so that the progress bar shows up before line B starts executing? I've tried validate(), repaint(), using threads and setting the size of the frame to zero and back again, but none of those seem to work. If I pop up a dialog after I add the progress bar to the split pane, the progress bar shows up as soon as the dialog shows up.
This code is inside a ListSelectionListener on a table elsewhere on the GUI, in case that's relevant.
I think I don't understand some basic principle about how to get the GUI to be updated immediately after I make some change.As suggested, I have prepared a compilable demonstration. I figured out that the
problem I was having before was that I was trying to join the background and
event-processing threads (I had been using threads, but I didn't show that code in the
version I posted since it didn't seem to matter). After I eliminated the join, the progress
bar is displayed, but the user can do other things while the image is loading. I want to
prevent the user from doing that. I switched the cursor to a wait cursor, but that doesn't
seem to prevent it.
In particular, while it is loading, the user should be able to:
* resize the window
* minimize the window and bring it back up
* ideally, adjust the split pane, but that isn't critical
but NOT:
* select a different row in the table
* sort the table
* use the menus
Any attempt by the user to perform the disallowed actions should have no effect either
while the image is loading or after it has finished.
(That is, the disallowed events should not simply be queued for later.)
I wonder if there is a simple way to accomplish that.

Order-column needs to be numeric?
Hi,
I've got a List attribute mapped as one-to-many that I want ordered by a
date column, but I am getting an exception saying that the order-column
specified is not numeric. Does my order-column really have to be numeric?
Why can't I order by a date column (or a varchar for that matter)?
Thanks,
AlexAbe,
I would like to propose ordering lists by any column in the next feasible
version of Kodo. This would be very useful. It would be more efficient
than in-memory sorting. I can't forsee any problems with it - it would
simply translate to an "order by" SQL clause.
Meantime I will use a TreeSet with custom Comparator as you suggest.
Thanks,
Alex -

The most intersting part of this error is that it is not permannent rather it comes 8 out of 10 times (last 1-2 days only)
Please give me any pointers about the same. I have googled through the same but did not get any concrete answer on the issue :(

Please offer help on indexing a textbook
I really need help on an assignment. It is supposed to create an index for a textbook and it has to be implemnted using trees.
Generate an index for a book.
The Input:
The input file is specified as a command-line argument (use args). Be certain to check the validity of the file.
The input file consists of a set of index entries. Each line consists of the string IX:, followed by an index entry name enclosed in braces, followed by a page number that is enclosed in braces. Each ! in an index entry name represets a sub-level. A |( represents the start of a range and a |) represents the end of the range. Occasionally, this will be the same page, and in that case, only output a single page number. Otherwise, do not collapse or expand ranges on your own. As an example, here's a sample input:
IX: Series {2}
IX: {Series!geometric|(} {4}
IX: {Euler's constant} {4}
IX: {Series!geometric|)} {4}
IX: {Series!arithmetic|(} {4}
IX: {Series!arithmetic|)} {5}
IX: {Series!harmonic|(} {5}
IX: {Euler's constant} {5}
IX: {Series!harmonic|)} {5}
IX: Series {5}
The corresponding output is:
Euler's constant: 4, 5
Series: 2-5
arithmetic: 4-5
geometric: 4
harmonic: 5
(1)You must construct a general tree with a root node(the value stored in the root node will just be the word INDEX which should be the first item printed out - this is in addition to the output specification in the text) and its children consisting of top-level index terms, the next level of children consisting of sub -level index terms and so on;
(2)Each node(except the root) must store the index term and page ranges;
(3)In the general tree implementation the siblings need to be stored in a certain way so that a certain tree traversal algorithm will print out the index in the correct way.

A red-black tree is a binary search tree where every node has two children or is a leaf.
It ensures O(log N) search times, at a cost of a more complicated insertion (and deletion)
process. In a red-black tree, every node is colored either red or black, with a black root
node, though a black root node isn't a requirement. In addition, if a node is red, its
children must be black and every path from root to leaf (or null child node) must
contain the same number of black nodes. These rules allow balancing

I'm even offering the buy the program to make it more proffessional...the payment is as much duke dollars as i can give...We can also negotiate on e bay using real dollars, but the assignemtn is due tonite and i don t have much time... If someone will most kindly take a look, i will be greatly indebted and humbled...isn t there anyone on this site who actually loves solving this kinda stuff?actually, your solution was how I found about this forum. go to google,
type in "index a textbook" + java, the forum pops up. Your solution has helped me a lot, I based my assignment on yours, just look at my main file. The difference was, I had to use a tree. That was more confusing than a linked list. -
Off Topic: Hidden Features of Java
Happy Friday everyone,
I stumbled upon this conversation on Stack Overflow last night about "hidden" features of Java. Although I knew about most of them (mostly learned from reading posts here in the past few months), thinking about less-often used features of the language is a fun refresher (at least for me).
Can anybody think of any more "hidden" features of Java? Or just something interesting that not many people are familiar with?
Here's the link: [http://stackoverflow.com/questions/15496/hidden-features-of-java|http://stackoverflow.com/questions/15496/hidden-features-of-java]
Edit- To make things a bit more interesting, I'll throw some Dukes at people who show me interesting things.

Here's one I banged my shins on the other day. Comparator may change Set semantics:It's always bothered me that TreeSet relies on Comparator to define equality.
Note that the ordering maintained by a set (whether or not an explicit comparator is provided) must be consistent with equals if it is to correctly implement the Set interface. It bugs me because it's not an explicit requirement of Comparable or Comparable. Therefore, if I did:
set.add("Hello");
System.out.println(set.contains("World"));I would expect false to be printed (in other words, like HashSet, I would expect it to do a final equals() to make sure). But it's not.
However, in your example, it's easy to see why TreeSet could not possibly allow that. If you added 2 Objects that were comparatively equal, it would be impossible to traverse the tree to find anything.
