Need Help with strings

[deltag]

i have a test pretty soon and i can't figure out how to replace a part of a string from the original string to something else using charAt() and length() not any built in commands.

thanx

Personally, Id use two strings, and the substring command.

code:

String initial="helpme",after=""; after=initial.substring(0,4)+" yourself" System.out.println("Initial: "+initial); System.out.println("After : "+after);

I think that should work properly...sorry if it doesnt.
