whats wrong?

import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner scan = new Scanner (System.in); String x = scan.nextLine(); x.replace ("o" , "p"); System.out.println (x); } }

replace doesn't change the original string, it returns a modified version of that string. x = x.replace("o","p"); should work.

String are immutable.. Read about that topic.. And if you need replaced result.. You need to save result by replace like x=x.replace("o","p"); This only replace first occurrence of "o", For all, use x=x. replaceAll("o", "p") ;
