arr[0] = "a";
arr[1] = " ";
arr[2] = "I hope this helps."

Alternatively,

String[] arr = { "a", " ", "I hope this helps." };

The Java Tutorial is a good place to look for answers. This section covers
arrays, and initialization:
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/arrays.html

Reading the entire tutorial would help you with the basics, and give you a much
better understanding of the language.


One answer to your question might be:

String[] arr = { "a", "", "something else"};

Perhaps you want:
String[] arr = new String[3];
Arrays.fill(arr,'a');

I know this works on char[], I've never tried it with String[] but I
think there's an overload for Object[]. Give it a shot!

Loop through every value, and set it how you want it.

 

[Garg]

thanks for the help.

what i am doing is

String[] arr;
String str = "Tarun|garg";

arr = str.split("\\|");

now this will split the str and arr will contain two values.
what i need to do is i have to fix the array like 10 and rest 8 fields
of the array should contain ''.

Eric already answered this, didn't you read his reply?
String[] foo = { "Tarug", "Garg", "", "", "", "", "", "", "", "" };

or (easier to apply to larger arrays)
String[] foo = new String[10];
foo[0] = "Tarug";
foo[1] = "Garg";
for (int i=2; i< foo.length; i++) foo = "";

or maybe (untested)
String[] foo = "Tarug|Garg||||||||".split("\\|");
