String replace not working properly

[phyzix5761]

This is a small example of my code where I am trying to replace a char with another while iterating through a for loop. The problem is that it's not replacing the char.

public class Test
{
    private static String[] testVars = {"ʤUser1", "ʤUser2", "ʤUser3"};
    
    public static void main(String[] args)
    {
        for (int k = 0; k < testVars.length; k++)
        {
            testVars[k].replace("ʤ", "Dž");
            System.out.println(testVars[k]);
        }
    }
            
}

The output I am getting is:

ʤUser1
ʤUser2
ʤUser3


EDIT Found the solution. Needed to create a string to hold the replacement.

Strings are immutable so you have to assign the return value of the replace method to the reference variable again; i.e.

testVars[k]= testVars[k].replace("ʤ", "Dž");
