Doubt in compareTo method while sorting string having special character

I used compareTo method of String to sort below strings
??che
??in
p?ch?
I got the output in the below order :
p?ch?
??che
??in
Why does ??che appear before ??in because from http://www.asciitable.com/ ascii value of *?* is *154*
and that of *?* is *130* so shouldn't ??in appear ??che?
Regards,
Joshua

JoshuaAre you sure your strings are using ASCII encoding, and not unicode? If it's the latter, the ASCII table won't matter at all and you'd need to check the values in a unicode table.

How Create New Folder in KM with Name having Special Character

Hi,
How to create new Folder in KM with name having special character in it.
Right now its not allowing me to create folder when i have Colon( as one of the character in name of the folder.
Is there a way to change this validate?
Any help is appriciated.
Thanks

Hi DK,
I'm not sure about special chars such as ":" but ifyou need to have your folders displaying special language chars (like german chars), have a look into the below link.

Sorting string by first character

What is the easiest way to sort strings by the first character? I can sort by a complete string match, but what I really want to do is just sort by the first letter of character. Is there a way to do something like a reverse concatenate?
Thank you

Error while releasing transport request - Special character "_" in generic

Hi all,
we're receiving the error Special character "_" in generic key when releasing a best practice transport.
Note 1304725 describes my error, but the solution cannot be implemented. The reason for this is that we do not have an individual entry for eacht yb_PS,..,
but we have only one entry where field BWERT has a wildcard '*' as entry.
Does anyone has some idea how to solve this ?
kind regards !

Hello Bjorn,
How did you get this solved?
I'm having nearly the same issue:
A custom-table with a total key lenght of about 365 characters. As soon as I enter a special character (_) in the key field just before the position 120, the message tk287 rejects the entry. Entering the special character in a key field at about key position
60, there's no message rejecting the entry.

Invoice Number Having Special Character

Hi Team,
we have a requirement to compare Invoice number from master data to child data.
We are storing the Master Invoice number into variable to access it in Child Data.
Our issue is the invoice number is having a special character i.e. '-' because of which equal to function is not working.
Could any one guide on this issue.
Following is the code
?xdoxslt:set_variable($_XDOCTX, 'v1', ssInvoiceNumber)?>
<?if:(xdoxslt:get_variable($_XDOCTX,'v1')=ssInvoiceNumber)?> Display data <?end if?>
Even though the data are not same the if loop get executed and its display unwanted data.
invoice number as (1-100678,1-100677,1-100679).
Cheers,
Andy

do you want to remove HYPHEN from the numbers before comparing ?
use
<?translate(ssInvoiceNumber,'-','')?> to remove the HYPHEN
<?if:(xdoxslt:get_variable($_XDOCTX,'v1')=translate(ssInvoiceNumber,'-',''))?>

Reading a string containing special character from a result set

My Code....
PrintStream p = new PrintStream(fout);
if (connection == null)
connection = getConnection();
CallableStatement proc = connection.prepareCall("{call testing_read()}");
rs = proc.executeQuery();
while ( rs.next() )
String page2 = rs.getString(1);
System.out.println(page2);
rs.getString(1); is a string value eg. 'Rebekah \n Govender' that is being set in a stored procedure.
The output of my program is :'Rebekah \n Govender' , i need for it to read the special characters, and produce this output :
Rebekah
Govender
Without using a result set , it works fine.
eg.
String page2 = 'Rebekah \n Govender'
System.out.println(page2);
Will give an output of :
Rebekah
Govender
I need to read values from the results set, pls help me someone....
Please help....

String page2 = rs.getString(1).replace("\\n", "\n"); When you include source code in your posts, please enclose it in CODE tags. There's a button for that above the input textarea.

you can try something like this:

public class Main {

try {

Sort strings. How to make it case-insensitive?

I wish to sort some String objects. TreeSet does it automatically, but letters are case-sensitive. Is there some static method that sorts Strings without regard to letter cases, so that "String B" will come between "String b" and "String C"?

SortedSet mySet = new TreeSet(String.CASE_INSENSITIVE_ORDER);
mySet.add("monkey");
mySet.add("Zebra");
mySet.add("Aardvark");
for(Iterator i = mySet.iterator(); i.hasNext(); ) {
System.out.println(i.next());
}I think you probably could have figured that out by looking at the API.

Hi,
Our PI is getting data from WebSphere MQ and pushing to SAP. So our sender CC is JMS and receiver is Proxy. Our PI version is 7.31.
Our connectivity between the MQ is success but getting the following error while trying to read the payload.

Hi Amarnath,
Where exactly you are getting this error?
If you are getting at JMS Sender communication channel, try to stop and start the JMS communication channel and see the status, also use XPI Inspector to get the exact error log.

Approval task SP09: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'

Hi everyone,
I just installed SP09 and i was testing the solution. And I found a problem with the approvals tasks.
I configured a simple ROLE approval task for validate add event. And when the runtime executes the task, the dispatcher log shows a error:
ERROR: Evaluation of approvalid failed with Exception: while trying to invoke the method java.lang.String.length() of an object loaded from local variable 'aValue'
And the notifications configured on approval task does not start either.
The approval goes to the ToDO tab of the approver, but when approved, also the ROLE stays in "Pending" State.
I downgraded the Runtime components to SP08 to test, and the approvals tasks works correctly.
Has anyone passed trough this situation in SP09?
I think there is an issue with the runtime components delivered with this initial package of SP09.
Suggestions?

Hi Kelvin,2016081
The issue is caused by a program error in the Dispatcher component. A fix will be provided in Identity Management SP9 Patch 2 for the Runtime component. I expect the patch will be delivered within a week or two.
For more info about the issue and the patch please refer to SAPNote 2016081.
@Michael Penn - I might be able to assist if you provide the ticket number

Eclipse is claiming that the Integer class does not have a compareTo(Integer) method.It will be complaining that Integer does not have a compare method, the specific method you are trying to override that does not exist.
However the Integer class does have a compareTo() method that you can override, refer to the API

Understanding Comparable and the compareTo( ) method

I have a Contact object which lists a person's information for a "phone book" program.
I am trying to sort the Contact objects in a Vector by way of their last name fields.
I am having a hell of a time trying to use this compareTo( ) method.
I'm really struggling with understanding how to go about making the method work with a comparison. Most of the examples which I find compare "numbers' and not strings which make it more difficult to understand.
I have implimented the comparable Interface at the start of my class. To sort my Vector, I'm attempting to use the compareTo( ) method to determine which Last name field has the lower value. I keep going back and forth working through the error messages I receive and I'm just stumped trying to figure out how to get this thing to work. Can someone please point out the mistakes without writing too much code? I don't want someone to do the work for me. Here is the code:
import java.io.*;
import java.util.*;
class PhoneBook implements Comparable{
     private static Vector v = new Vector();
     private static Iterator iter = v.iterator();
     private static int num, index;
     private static Contact firstContact, secondContact, temp; //"static" to be referenced from main
     public static void main(String arg[])throws Exception {
          Contact c;
          String str;
          BufferedReader br = new BufferedReader(
      new InputStreamReader(
           new FileInputStream(
                                       new File("contacts.txt"))));
          while((str = br.readLine()) != null){
           v.add(c= new Contact(br.readLine()));
           num = v.size();
           for(int i=0; i < num; i++){
      firstContact = (Contact)v.elementAt(i);
           if(v.elementAt(++i) == null)
                break;
           else
                secondContact = (Contact)v.elementAt(++i);
           index = compareTo(firstContact);
           if(index == 1){
                   temp = (Contact)v.elementAt(i);
                   v.setElementAt(v.elementAt(++i), i);
                   v.setElementAt(temp, ++i);
          public static int compareTo(Object person){
     int x = ((Contact)person).getLName().compareTo(secondContact.getLName());
     return x;
}yet still I get the following compiler error:
PhoneBook.java:4: compareTo(java.lang.Object) in PhoneBook cannot implement compareTo(java.lang.Object) in java.lang.Comparable; compareTo(java.lang.Object) and compareTo(java.lang.Object) are static
class PhoneBook implements Comparable{
^
1 error

You are pretty close here except for one incorrect basic assumption. Your compiler error is because you are trying to implement compareTo() with a static method. However, this is irrelevant because it is not the PhoneBook class that should implement Comparable, but the Contact class.
The idea is that other functions can call the compareTo() method on an instance of Contact and pass a reference to a second instance. Based on the result, the relative sort order of the two objects can be determined.
e.g.Contact c1 = new Contact("Smith", "John");
Contact c2 = new Contact("Jones", "Alan");
int x = c1.compareTo(c2);In your example, you can implement compareTo() to use the corresponding method in String. For compatibility, you should also implement equals().
public class Contact implements Comparable {
   public int compareTo(Object otherContact) {
       Contact otherC = (Contact) otherContact; // could throw exception
       return getLName().compareTo(otherC.getLName());
   public boolean equals(Object otherContact) {
       Contact otherC = (Contact) otherContact; // could throw exception
       return getLName().equals(otherC.getLName());
} // end of class Contact I haven't compiled or tested the above code nor does it deal with exceptions (e.g. otherContact is not an instance of Contact) - I'll leave that to you! You'll also need to change your PhoneBook sort routine to invoke firstContact.compareTo(secondContact)
FYI - I understand that this is an academic exercise and so you may need to code the sort yourself, but once Contact implements Comparable, you could sort the Vector using standard Java methods. Check out java.util.Collections - there is a method that will perform your sort in one line of code.
Good Luck.

Overriding compareTo method for ints

I'm having a problem writing the overloaded compareTo method for my class. Ideally, the class will be used in collections, and has to be sorted by an int value. I've found a messy way to do this by converting the int values into strings, then comparing those, but I would like to know if there is a better way to do this.

You could subtract, unless you are worried about over/underflow.
Then you can just compare the ints the old-fashioned way:
import java.util.*;
public class Test implements Comparable<Test> {
    int x;
    public int compareTo(Test that) {
        return this.x - that.x;
        //return this.x < that.x ? -1 : this.x > that.x ? 1 : 0;
}

Java CompareTo Method

does anyone know how the string compareTo method actually works? I am trying to use a binary search to find a word in an arraylist with a specific prefix.
i know that the compareTo method returns a 1 0 or -1 based on what the result of the comparison is but im interested in teh actual way that the comparison takes place.
Since i will be comparing a prefix to a complete word, i would like to know if this would cause any problems due to the difference in string lengths.
Do you guys have any other idea on how i can use a very fast searching method to search a sorted arraylist of words to see if any word with a specific prefix exists?

i did that but i would still have to use compareTo because if the middle element does not have the prefix i am looking for then i would have to know if its on the right half or the left half of the Arraylist by comparing. right?
     public static int bSearch(ArrayList list, String pref)
          int result = -1;
          int low = 0;
          int high = list.size()-1;
          String s="";
          while(low <= high || result==-1)
               int mid = (low + high)/2;
               s = (String)list.get(mid);
               if(s.startsWith(pref)==true)
                    result = mid;
               else if(pref.compareTo(list.get(mid))<0)
                    high = mid - 1;
               else
                    low = mid + 1;
          return result;
     }this is what i got so far but i am not sure if using compareTo method the way i am using it will work or not.
