QUESTION 9

1. Consider the following Java code. class MyTest { public static void main(String[] args) { SubClass s = new SubClass(); s.superClassField = 20; System.out.println(s.toString()); } } class SuperClass{ int superClassField = 10; public String toString(){ return "Superclass field is " + superClassField; } } class SubClass extends SuperClass{ public String toString(){ return "Subclass field is " + super.superClassField; } } Which of the following statements are correct?
   1. Given the object s, any other class could change the value of superClassField.
   2. Making superClassField to be private would improve encapsulation, and the code would compile.
   3. Making superClassField to be private would improve encapsulation, but the code will not compile.
   4. Making superClassField to be protected would improve encapsulation, and the code would compile.
   5. Without any modification the code output is Subclass field is 20.
   6. Without any modification the code will not compile.
