Need help with a string manipulation

String s = "ALPHA OMEGA(AOMEGA)";

String s1 = s.substring(0,s.indexOf("(")) + System.getProperty("line.separator")  +  s.substring(s.indexOf("(")+1,)s.indexOf(")"):

This is testded - use tis code:

        String s1000 = "ALPHA OMEGA(AOMEGA)";

String s1001 = s1000.substring(0,s1000.indexOf("(")) + System.getProperty("line.separator")  +  s1000.substring(s1000.indexOf("(")+1,s1000.indexOf(")"));

        System.out.println(  s1001);

Select allOpen in new window

Output:

ALPHA OMEGA
AOMEGA

Select allOpen in new window

Another option (don't know if you need one more line to beadded i n foront of the contestnd iof paerenthedss)

   String s1002 = s1000.replaceAll("\\((.*?)\\)"," $1 ");

          System.out.println(  s1002);

Select allOpen in new window

Output:

ALPHA OMEGA AOMEGA 

Select allOpen in new window

This would be with line break:

  String s1002 = s1000.replaceAll("\\((.*?)\\)","\n$1 ");

          System.out.println(  s1002);

Hi Yan,

Sorry I need it to return two things

so the functions should be returnNTid - AOMEGA
and
functions should be returnFullName - ALPHA OMEGA

can you write this into two functions format

      String s1002 = s1000.replaceAll("\\((.*?)\\)","|$1");

        String [] sss1003 = s1002.split("\\|");

        String s1004 = sss1003[0];
        String s1005  = sss1003[1];

        System.out.println(s1004);
          System.out.println(s1005);

Select allOpen in new window

ALPHA OMEGA
AOMEGA

Select allOpen in new window

you can use this static method which will return array of two strings:

  public static String [] getTwoStrings (String s1000){
        String s1002 = s1000.replaceAll("\\((.*?)\\)","|$1");

            String [] sss1003 = s1002.split("\\|");

            return sss1003;

    }

Select allOpen in new window

Oops found some edge cases

NEW USER (1)(NEW USER (1))
NEW USER (2)(NEW USER (2))
NEW USER (3)(NEW USER (3))

the data contains things like these also - How do I handle that

    String s1000 = "ALPHA OMEGA(AOMEGA)";
 for(String s : getTwoStrings(s1000)){
            System.out.println(s);

        }

Select allOpen in new window

output:

ALPHA OMEGA
AOMEGA

Select allOpen in new window

Sorry for my limited (or almost zero) knowledge of java  from the following code How can I selectively
print either ALPHA OMEGA
or
AOMEGA

I tried s[0] and s[1] but it was showing an error

String s1000 = "ALPHA OMEGA(AOMEGA)";
 for(String s : getTwoStrings(s1000)){
            System.out.println(s);

        }

Yuou have to prioveide this method in the same class:

 public static String [] getTwoStrings (String s1000){
        String s1002 = s1000.replaceAll("\\((.*?)\\)","|$1");

            String [] sss1003 = s1002.split("\\|");

            return sss1003;

    }

Select allOpen in new window

and quote waht was the error on waht line

That your other case is quite different - look through them all and formulate
how we distingusish different parentheses - explain it to me - I'll
then try to think about something

For now make sure that this one wworks for you

This is the complete class which will
split your original string - it compiles and executes as a whole - without any changes.
Try and you'd see it

public class SplitToTwo {


    public static void main(String[] args) {
     String s1000=    "ALPHA OMEGA(AOMEGA)";

            for(String s : getTwoStrings(s1000)){
            System.out.println(s);

        }

    }

      public static String [] getTwoStrings (String s1000){
        String s1002 = s1000.replaceAll("\\((.*?)\\)","|$1");

            String [] sss1003 = s1002.split("\\|");

            return sss1003;

    }
}

About your special case - formulate more strictly how to distinguish the parentheses
and we;ll try to do something about it. It is much more difficult though.
Still full understanding which parentheses not to consider
enclosing parentheses needs clear understanding.
