The value of a variable does not get updated when I pass that to a method to do so?

Question

package com.mkyong.test;

public class Main {

    public static void main(String[] args) {
        String something = "";
        callSomething(something);

        System.out.println(something);
    }

    private static String callSomething(String something) {
        something = "Hello Wrold !";
        return something;
    }
}

Answer 1

No, in the method, you are changing the reference of the local variable something.

Change your method call to:

something = callSomething(something);
