Give it a shot! ;)

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

thanks for the help.what i am doing isString[] 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 fieldsof the array should contain ''.Garg

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