Question 1

1class ClassOne{
2    public void methodOne(){
3        // ...
4    }
5    public void methodTwo(){
6        // ...
7        methodOne();
8        // ...
9    }
10    public void methodThree(){
11        // ...
12        methodTwo();
13        // ...
14    }
15}
16class ClassTwo{
17    public static void main(String[] args){
18        // ...
19        ClassOne c = new ClassOne();
20        c.methodThree();
21    }
22}

Consider the code given below. How many activation records are created while executing this code? class ClassOne{ public void methodOne(){ // ... } public void methodTwo(){ // ... methodOne(); // ... } public void methodThree(){ // ... methodTwo(); // ... } } class ClassTwo{ public static void main(String[] args){ // ... ClassOne c = new ClassOne(); c.methodThree(); } } Figure from the original question paper Consider the Java code given below. public class NumberEvaluation { public static void main(String[] args) { int number = 10; do { number--; } while (number > 5); switch (number) { case 5: System.out.println("Low"); break; case 6: System.out.println("Medium"); break; default: if (number > 6) { System.out.println("High"); } else { System.out.println("Unknown"); } break; } } } What will the output be?
