Ordering a Hashmap
Hello,
HashMap<String, String>trendRangeMap = new HashMap<String, String>();
trendRangeMap.put("1", "Curr. Mo.");
trendRangeMap.put("3", "3 Mo.");
trendRangeMap.put("6", "6 Mo.");
trendRangeMap.put("12", "12 Mo.");I put the previous code into a HashMap. I want to the order of the data that I put into the HashMap to come out in the same order. I need to input this data into a website. Where the HashMap key is equal to the value in the input tag and the HashMap value is equal to the value that is actually displayed as a label by the radio button. I know lists can be ordered, but my problem is that I need both values, HashMap key and value. I want the output to be ordered by key.
How about your code?
Map<String, String>trendRangeMap = new LinkedHashMap<String, String>();
trendRangeMap.put("1", "Curr. Mo.");
trendRangeMap.put("3", "3 Mo.");
trendRangeMap.put("6", "6 Mo.");
trendRangeMap.put("12", "12 Mo.");
System.out.println(trendRangeMap);Output:
{1=Curr. Mo., 3=3 Mo., 6=6 Mo., 12=12 Mo.}The toString method being used here implicitly is iterating over the
collection in the order entries were added.

Is order in Hashmap guaranteed, if not updated?
Hello,
Lets say I have created a hashmap with 5 records and when first I checked the order of records is: 1,3,2,5,4.
If I don't change this hashmap records and not even add/delete records, can I assume that if I print the records again, I shall get them in the same order?
Regards,
ChintanBut LinkedHashMap will change the order when we
access it. It will store the last accessed recordson
top. So, again the order is changed :-(That's false.Yes, it's false. "This linked list defines the iteration ordering, which is normally the order in which keys were inserted into the map (insertion-order). Note that insertion order is not affected if a key is re-inserted into the map....A special constructor is provided to create a linked hash map whose order of iteration is the order in which its entries were last accessed, from least-recently accessed to most-recently (access-order)." -
I dont see what i do wrong here.
Hi
I have a bit of a problem here. Im trying to create an object in my test class. However, Since i have some parameters in my constructor i get an error message in the test class:
Error(8,27): no declaration allowed here, use '{'
and
Error(8,34): , expected
If i remove the parametrs from the constructor, I dont get any errors. Thing is, I think there should be parameters in the contructor since its parameters that the object always has.
Here is the Classes contructor code:
public Kund(String nummer, String namn, String adress){
order=new HashMap<String, Order>();
setNummer(nummer);
setNamn(namn);
setAdress(adress);
}and here is the code from the testclass when im trying to create and object:
public static void main(String[] args) {
Kund k = new Kund(String nummer, String namn, String adress);
k.setNummer("125");
k.setNamn("Peter");
k.setAdress("Lund");and as stated above these are the error messages i get:
Error(8,27): no declaration allowed here, use '{'
Error(8,34): , expected
Anyone have a pointer to what im doing wrong?Morpheus wrote:
On that note though..Why having both parameters and then also set and get methods in the class? Seemes like double code for the same thing.It is. It is often done for flexibility and convenience: you can either pass the values to the constructor, or use a no-argument constructor and set the values later, if you wish.
You can also use the setters to change the values, if someone's address changes for example. -
Is it possible to insert a value in a hash map at a perticular index ?
Hello Techies,
I have a drop down list which is used to select a contry name. I also contains " All " option which is used to select all countries.
I am using HashMap for this drop down list for getting corresponding value.
Now, my requirement is the " All " should display as the first in the drop down list. Hash map didn't support bcoz it is in sorted order,
Can any one help me with alternative solution ?
Thanks in advance.
JavedNow, my requirement is the " All " should display as the first in the drop down
list. Hash map didn't support bcoz it is in sorted order,Rather HashMap doesn't support this because according to the first paragraph
of its API documentation "This class makes no guarantees as to the order of the
map; in particular, it does not guarantee that the order will remain constant over
time".
Is the drop down list a JComboBox? If so how are you using the hash map?
And can't you just create an array from the hash map's keys, putting "All" at the
start? -
Retrieving all values from hashmap in order you put them in
Hi guys,
I want to retrieve all values from a HashMap in the order I put them in.
So I can't use the values() method that gives back a collection and iterate over that.
Do you guys know a good way to do that ?You can just do something like this:
class OrderedMap
private final Map m_rep = new HashMap();
private final List m_keys = new ArrayList();
public Object get( final Object key )
return m_rep.get( key );
public Object put( final Object key, final Object value )
final Object result = m_rep.put( key, value );
if ( result != null )
m_keys.add( key );
return result;
public Object remove( final Object key )
final Object result = m_rep.remove( key );
if ( result != null )
m_keys.add( key );
return result;
public Iterator keyIterator()
return m_rep.iterator();
}Then use it like this:
for ( Iterator it = map.keyIterator(); it.hasNext(); )
final Object value = map.get( it.next() );
}This will be in the order you put them in. However, if you want to do this correctly, you should implement the Map interface and add all the methods. Another thing you can do is download the JDK 1.4 source, learn how they did and do it the same way for 1.2.

How to access the element s in a hashMap with order
Does anybody know how to access the elements in a hashMap with order.
I know set is a collection that doesn't gaurantee the order so the iterator of keySet will not gaurantee the order.
Is there any way to solve this?
ThanksIf you mean the order in which the key/value pairs where added to the
map, have a look at the LinkedHashMap class. If you mean 'natural'
order, you shouldn't be using a HashMap at all then; have a look at the
TreeMap class instead.
kind regards,

Order by the names in hashMaps which are contained within a collection
Hi All,
Is there a way to order by the names in hashMaps which are contained within a collection?
Collection-->hmp1(nrPerson1, nameB);
hmp2(nrPerson2, nameC);
hmp3(nrPerson3, nameA);
Now what i need to display is (nrPerson3,nameA), (nrPerson1,nameB), (nrPerson2, nameC)...
Any suggestion will be greatly appreciated!
ShuaibingI just set the TreeSet with the values as you suggested, but the results seems to the same as usual, Can you check the following codes? I think I need have to give a initial parameter for the TreeSet constructor, but I do not know how to write the Comparator.

while(iter.hasNext()){
HashMap hmp=(HashMap)iter.next();
hmpForOrder.put(hmp.get("name"),hmp.get("nrContact"));
treeSet.add(hmpForOrder.keySet());
//print the ordered, unique set
Iterator iterator = treeSet.iterator();
while( iterator.hasNext() ) {
System.out.println( "the list of sorted intermediary companies' names="+iterator.next() );

Hi all
Until now in my program i use a HashMap collection to store my objects. The problem i have now is that the objects are too many (over 1.000.000) so keeping them in memory in a hashmap collection is impossible. So the solution (?) is to keep them in a file and retrieve the objects i want from the file directly, but i would like to have the ability to retrieve information from the file in constant time as before. Is that possible, can somehow have a hashmap in the file? If yes can you tell me how or post a link with information?
thank you in advancePitelk wrote:

Is that possible, can somehow have a hashmap in the file? If yes can you tell me how or post a link with information? If keeping your objects in memory is unwieldy or impossible, and you want to retrieve them randomly by some key, then you probably want a database. There's one included with the JDK download, or you can download a few one like Postgres or MySQL. -
Re-ordering 2 files, can you help me speed it up?
Hi all - this is kind of complicated. I have 2 files, each contains identical blocks of information (identified by the word "Processing") but in different orders. So I have to find the block in the first file, write it to an output file, and then find the matching block in the 2nd file and write it out - Thereby insuring that the processing blocks in both outfiles are in the same order. (What my end result should be is 2 files I can compare, looking for info inside the blocks that may differ).
I've got a function now, but it's sloooooow. The biggest file that I have to read & manipulate like this is 14,406 kb in size. Takes about 15 to 20 minutes and eats up 97% of my resources. The code is below, can anyone help identify bottlenecks? (or better ways to accomplish this...)
Thanks!!!
/* This function reads one file line by line. if a line contains the word "processing",
then another stream is opened (same file, starting at same line), and data is read and
written to the "out" file until "processing" is found again. A 2nd file, with the same
info but in a different order, is opened & searched for the same processing block, this
data is entered into the 2nd out file. This is basically a re-ordering scheme.*/

}I'd suggest one quick and easy thing you can do is not re-scan the second file on each processing block.
During the scan, if it is not the block you want, you could save the file location into a HashMap with the processing line/identifier as the key. You could also save the "furthest" location you've progressed into the file. Then when you get a processing block from the first file, check if it matches one in your HashMap, and immediately seek to that location and process the block. If it's not in the HashMap, seek to the furthest location you saved, and continue scanning procedure, adding processing blocks to the HashMap (again) until you find the block you want. -
An easy way to sort a HashMap by Key?
Hi everyone,
Is there any way to sort a HashMap by the key value using API 1.3.1?
Thanks.Try using a TreeMap implementation instead. It'll maintain the keys in sorted order, as long as they have a Comparable implementation to tell the data structure how to sort them.
If you've written your code properly, it'll be an easy change:
// instead of this
// Map myData = new HashMap();
// use this.
Map myData = new TreeMap();As long as you've used the Map as the reference type it's easy to switch. -
JTable displays string in wrong order : my code problem or Java problem ?
I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
It would display it as : [Snowboarding[123456789
For a string like : "Chasing toddlers"+"<123456789>"
It would display it as : <Chasing toddlers<123456789
It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
Is there anything wrong with my code ? Or is this a Java problem ?

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* <p/>
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* <p/>
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* <p/>
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

* TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
* or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* <p/>
* TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* <p/>
* When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
* header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound sort.
* </ul>
* <p/>
* This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

"Preview and Print " report extension in Order Management
Looking for help on how to add extra information to this report.. I did setup the profile to implement the how to implement PrintExtensionObject interface with method getPrintExtensionXMLFragment.... and created the class file and compiled on Java_top. ( Am very new to java)
-- enabled the logs
-selected an order in OM and via action button (preview and print)
--Shows error message "An error occured during the PDF document generation. Please contact your system Administrator."
As per the fnd logs table (SELECT * FROM fnd_log_messages WHERE message_text LIKE '%PrintAM:writeBusinessDoc%';)
shows the following ..

So I am sure that the issue is on the class which I made.. but not sure what is the cause (Again as mentioned I am new to java) and can anyone help me on this..
( I did check the PrintAMImpl.java which calls this profile (Custom class) and can see the above message.

Any help will be appreciatedThere is a custom extension class available for this "Print and Priview" report. You can implement that and return the SQL Query in the class so that it gets executed and adds the custom attribute information at the end of XML file and you can modify the layout to add the information. The extended java class can return "select statement" or XML data. If it returns select statement code executes the query and adds the xml data at the end or returned XML data will be added. Look for Profile "OM: Printed Document Extension Class Name"

How can I get keys from Hashtable in the same order?
Hello, everyone.
I have a Hashtable containing key-value pairs, I need to get the keys in the same order as I use
method put(key,value) to save the key-value pairs. But I can only find Hashtable.keys() to fetch the keys in form of Enumeration and when retrieve the keys from the Enumeration,they are not in the original order!
The following is my code:
Hashtable ht = new Hashtable();
ht.put("Name","Harry Bott");
ht.put("Gender","Male");
ht.put("Age","25");
String[] Items = new String[ht.size()];
Enumeration e = ht.keys();
int i = 0;
while(e.hasMoreElements()) {
Items[i++] =(String)(e.nextElement());
The Items contains the keys but they are not in the original order.
Does anyone know how to get the keys from a Hashtable in the same order when they're put?
Thank you!yeah, another solution is to stored keys on a Collection at the same time you put them on the HashMap with its values.
Then when ur going to retrieve objects from the Map u iterate the Collection that has the ordered keys and use them. -
Most efficient way to make an ordered list?
Hi all,
I have a simulation where I have agents running around in an environment. These agents need to get the closest agent near them, and they have to do this a whole bunch of times each cycle -- closest predator to them, closest prey, closest mate, next-closest mate if that one isn't interested, etc. etc.
I realized that it would be faster if I just got all the agents in the vicinity ONCE, kept them in a sorted list, and then everytime you want the closest agent of a certain type, just search from the bottom of the list up until you find the first one of that type.
So here's the question: to make that list, I ask the environment for all the agents in the vicinity, and then go through them one-by-one. I find out the distance between myself and that agent. I then.... what?
I could put them all into an ArrayList, and then apply some sorting algorithm to that ArrayList. Or I can try to insert them in the right order WHILE I'm making the ArrayList. Or maybe there's some better Collection object that would be even more efficient -- somehow pushing them in and out of stacks, or whatever else smart programmers think up.
Can anyone suggest the most efficient way to do this? This is something that every agent has to do every step, so efficiency is key.
Thanks!
Edit: As a note, calculating the distance between two agents isn't free, and if I either sort or insert as I'm making it, the naive implementation (i.e. the way I would do it...) would require re-checking this distance for every agent in the list every single time a new agent was added. So maybe I could make some use of a HashMap, so that I can store these distances?
Edited by: TimQuinn on Oct 15, 2009 9:35 AMTimQuinn wrote:
Ok, thanks for all the great suggestions. I think that caching the distance in a wrapper object is a big plus, and then I can run some tests and see if using a built-in collections sorting algorithm or using a treeset is faster in my specific case. Thanks!
Any thoughts as to the idea of creating one giant map of the distance from each agent to every other agent just once, rather than having each agent work out their own distances to each other agent? I feel like this would be faster (at the expense of memory), but don't know how I'd start approaching it.Well, your idea of the Map would probably work. You would have to make some object that pairs up two agents, something like this:
public class AgentPair {
private final Agent a1, a2;
public AgentPair(Agent a1, Agent a2) { //...
public boolean equals(Object other) {
//if distance is a symmetric operation (a.distanceTo(b) == b.distanceTo(a)) then the reverse pair should also be equal
public int hashCode() {
return 37*a1.hashCode() + a2.hashCode();
}This assumes either that you don't override equals or hashCode in Agent, or that you properly override both.
Then you would have a map that you can populate, given an array of all agents:
Map<AgentPair, Double> distMap;
Agent[] agents;
for ( int i = 0; i < agents.length-1; i++ ) {
for ( int j = i; j < agents.length; j++ ) {
distMap.put(new AgentPair(agents, agents[j]), agents[i].distanceTo(agents[j]));
}Alternatively, if you're not sure you'll definitely use all of the computations, you could alternatively test to see if the computation result is in the map, and if not, perform it; otherwise, use the cached result.
Any thoughts? Should I make a new post? Abandon the idea?As always, try it and see. Essentially, it will be faster assuming these two conditions:
1) You would have to do more than n ^2^ (well actually n choose 2) distance calculations otherwise, and
2) Computing the distance costs more than retrieving from distMap (this +isn't+ a given!). If each Agent had a sequential ID, you could do a two-dimensional array of doubles which would speed up lookups.

How to get first item of hashMap w/out knowing the key
Hi
can someone tell me if there is a way to get first item from a hashMap when you dont know what the key is. as the get method expects a defined 'key'
reason I am asking this:
I am using struts 2 UI <s:radio> tag. this tag takes a hashmap and creates radio maps. it has a 'value' attribute and if something is passed to this attribute then that radio button is checked by default. the list that contains radio buttons is created dynamically so i dont know what is actually in the hashMap key's. but i do know that key's are string.
so just wondering if there is a way to get first item from a hashmap without knowing the key...thanks for the quick reply.
posted in java forums because thought it was a java API/workaround question. gave a little history because i didnt want people to start questioning my use of HashMap for this purpose..
anywhose..i've found a workaround.
If someone has a similar problem:
as the hashmap is being populated dynamically....set a String member of class to contain the first key thats being put in the hashmap. then have struts tag pick up that value.
also, through your post and reading hashMap api...its usefull to know that hasMaps do not gurantee the order of elements in it. So now I am using a TreeMap.
Thanks
