You are given the following two classes: Animal.java:
public class Animal {
private final int height = 120;
}
Tiger.java:
public class Tiger extends Animal {
public int height;

public class test1 {
public static void main(String[] args) {
Tiger t = new Tiger();
System.out.println(t.height);
}
}
test2.java:
public class test2 {
public static void main(String[] args) {
Animal t = new Tiger();
System.out.println(t.height);
}
}
test3.java:
public class test3 {
public static void main(String[] args) {
Animal t = new Animal();
System.out.println(t.height);
}
}
