What will be the result of compilation and execution of the following code?

public class Test {
    public static void main(String[] args) {
        TestClone t1 = new TestClone();
        TestClone t2 = (TestClone) t1.clone();
        for(int i = 0; i < t2.arr.length; i++) {
            t2.arr[i] = (t2.arr.length - i);

class TestClone implements Cloneable {
    int arr[] = {1, 2, 3, 4, 5};
    public Object clone() {
        try {
            return super.clone();
        } catch(CloneNotSupportedException e) {
            System.out.println("Clone not supported");
            return this;
The default implementation of clone() is used, therefore every reference variable of the new object will point to the same object as the variable of the original object.
