}
}

public class TestFinalReference
{
public static void main(String[] args)
{
//
final int[] iArr = {5,6666,99,45,3};
System.out.println(Arrays.toString(iArr));
//
Arrays.sort(iArr);
System.out.println(Arrays.toString(iArr));
//
iArr[2] = -65;
System.out.println(Arrays.toString(iArr));
//
//iArr = null;
//
final Person p = new Person(6);
p.getAge(23);
System.out.println(p.getAge);
//p = null;
