Duplicating an array in Java

Problem:

Write a problem that duplicates arrays by invoking the Object.clone() method.

Output:

{22, 44, 66, 88}
{22, 44, 66, 88}
{AB, CD, EF}
{AB, CD, EF}
{AB, XYZ, EF}
{AB, CD, EF}

Solution:

public class DuplicatingArrays {
public static void main(String[] args) {
int[] a = {22, 44, 66, 88};
print(a);
int[] b = (int[])a.clone(); // duplicate a[] in b[]
print(b);
String[] c = {"AB", "CD", "EF"};
print(c);
String[] d = (String[])c.clone(); // duplicate c[] in d[]
print(d);
c[1] = "XYZ"; // change c[], but not d[]
print(c);
print(d);
}

public static void print(int[] a) {
System.out.printf("{%d", a[0]);
for (int i = 1; i < a.length; i++) {
System.out.printf(", %d", a[i]);
}
System.out.println("}");
}
public static void print(Object[] a) {
System.out.printf("{%s", a[0]);
for (int i = 1; i < a.length; i++) {
System.out.printf(", %s", a[i]);
}
System.out.println("}");
}
}
