In this program why can arrays values stored in index be changed in both main method and mystery method, when the array is declared in main as a local variable? when the array is printed in the main method, the chnage took in the mystery method is present, why is this? is it a property of arrays?
public class referencemystery {
public static void main(string[] args) {
int x = 0;
int[] a = new int[4];
x = x + 1;
mystery(x, a);
system. out. println(x + " " + arrays. tostring(a));
x = x + 1;
mystery(x, a);
system. out. println(x + " " + arrays. tostring(a));
}
public static void mystery(int x, int[] a) {
x = x + 1;
a[x] = a[x] + 1;
system. out. println(x + " " + arrays. tostring(a));
}
}
