Get the characters from String.

[hariharan jayaprakash]

I have a String value like this

String a = "ab::cd::ef::gh::ij"

I need to iterate tat string and pick tat "ef" values from tat string..

values("ab,cd,ef,gh,ij") is dynamically generated string values..

how can i achieve tat?...

[Campbell Ritchie]

Do you not want to use the ready-made methods in the String class?

[hariharan jayaprakash]

hmm yeah like, i want to pickup the character symbols which is enclosed in my string("::") . so that while iterating, then i need to get tat middle value(""ef) of that string...

am i clear?...

[Wouter Oet]

And when you looked through the methods of the String class which seemed useful?

[hariharan jayaprakash]

I tried using split() method, for making the string to split with the symbol("::")enclosed in my string values.

but i couldn't achieve..

[Wouter Oet]

Could you show us your code? Because that should work.

[Nico Van Brandt]

    public static void main (String [] args)
    {
       String a = "ab::cd::ef::gh::ij";

       String[] b = a.split("::");

//       for(String c:b){
//           System.out.println(c);
//       }
       
       System.out.println(b[Math.round(b.length/2)]); // prints 'ef'
    }

@Nico: Please don't provide total solutions. The topic starter won't learn a thing from that. Like the forums description says:

Thanks Nico

but the values ab::cd:ef::gh::ij,


The values in bold are dynamically generated, In tat case, it won't work?.. rite?...

[hariharan jayaprakash]

@Wouter Oet: thanks for your concern, i tried like this, can you check?..

String a="ab::cd::ef::gh::ij"
int colon = 0;
Character outputString=null;

for(int i=0;i<a.length();i++) 
{
	Character temp = a.charAt(i);
	if( temp.equals(":"))
	{
		if(colon != 4)
			colon++;
		else
			outputString = a.charAt(i);       		 
	}
}

[Wouter Oet]

Let me ask you another question: why do you want "ef"? Is it because it is the third element? Or because it is the middle element?

[hariharan jayaprakash]

I want to get the third element, not like middle... and tat element size is not constant values... it may be "efgh" anything..

[Wouter Oet]

Than just use String.split() and access the third element of the array returned by that method.

[hariharan jayaprakash]

yeah its working as expected.. by accessing third element from the array directly...

thanks to everyone..
