In Java String is immutable - meaning not modifiable. You may modify the String reference and store a new string there.

Modify StringReplace() as give below..

public static String StringReplace(String t)
t=t.replace("j","i"); //It should have replaced "j" from "java" with an "i"
return t;


in main() as given below

s = StringReplace(s); //what happens over here?

This would give you desired result.

Also, variables are passed by value in Java. Assigning another value to t in line 6 and 12 has no effect.
