Does array changes in method?

Question

When I write like this:

public class test {

    void mainx()
    {
        int fyeah[] = {2, 3, 4};
        smth(fyeah);
        System.out.println(\"x\"+fy         


        

Answer 1

The int is a value type so 5 is passed directly into smth which can only modify the local copy. An array on the other hand is a reference type so the elements of that array can be modified.
