The absence of which statement leads to fall through situation in switch case statement?

1. continue
2. break
3. return
4. System.exit(0)

State the type of loop in the given program segment:

for (int i = 5; i != 0; i -= 2)
    System.out.println(i);

1. finite
2. infinite
3. null
4. fixed

The number of values that a method can return is:

1. 1
2. 2
3. 3
4. 4

Predict the output of the following code snippet:

String P = "20", Q ="22"; 
int a = Integer.parseInt(P);
int b = Integer.valueOf(Q);
System.out.println(a + " " + b);

1. 20
2. 20 22
3. 2220
4. 22
