Java for loop by value or by reference

Question

I figured out a a problem in my Code. First the code:

public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) {
           


        

Answer 1

Your for(String s : blablubb) loop is equivalent to the following code:

for(int i = 0; i < blablubb.length; i++ ) {
    String s = blablubb[i];
    s = "over";
}

Hopefully, from this you can see that all you are doing is reassigning a different value to s without changing blablubb[i]. This explains the output you see.
