s[1] = 0
s[2] = -12
s[3] = 9
s[4] = 10
s[5] = 3

11. Consider the following code:
Java
class A {
static int range = 9;
A() {
range = 80;
}
}
class B extends A {
int range; // Shadowing the static variable
void setRange(int r) {
range = r;
}
}
public class Test {
public Test() {}
public static void main(String[] args) {
A o1 = new A();
System.out.println(o1.range);
B o2 = new B();
o2.setRange(55);
System.out.println(o2.range);
A o3 = new B();
System.out.println(o3.range);
}
}
What is the output?
55 55
80 55 80
80 55 50 (Incorrect)
80 80 80 (Incorrect)
12. Consider the classes:
Java
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
Which statement is false?
Both variables a and b are instance variables.
After the constructor for class B executes, the variable a will have the value 7. After the constructor for class B executes, the variable b will have the value 8.
A reference of type A can be treated as a reference of type B.
