Q53. Given: 

public class Test1 { 

static void doubling (Integer ref, int pv) { 

ref =20; 

pv = 20; 

public static void main(String[] args) { 

Integer iObj = new Integer(10); 

int iVar = 10; 

doubling(iObj++, iVar++); 

System.out.println(iObj+ ", "+iVar); 

What is the result? 

A. 11, 11 

B. 10, 10 

C. 21, 11 

D. 20, 20 

E. 11, 12 

Answer:

Explanation: The code doubling(iObj++, iVar++); increases both variables from to 10 to 

11. 


Q54. Given:

Q55. Given: 

class Mid { 

public int findMid(int n1, int n2) { 

return (n1 + n2) / 2; 

public class Calc extends Mid { 

public static void main(String[] args) { 

int n1 = 22, n2 = 2; 

// insert code here 

System.out.print(n3); 

Which two code fragments, when inserted at // insert code here, enable the code to compile and print 12? 

A. Calc c = new Calc(); int n3 = c.findMid(n1,n2); 

B. int n3 = super.findMid(n1,n3); 

C. Calc c = new Mid(); int n3 = c.findMid(n1, n2); 

D. Mid m1 = new Calc(); int n3 = m1.findMid(n1, n2); 

E. int n3 = Calc.findMid(n1, n2); 

Answer: A,D 

Explanation: 

Incorrect: 

Not B: circular definition of n3. 

Not C: Compilation error. line Calc c = new Mid(); 

required: Calc 

found: Mid 

Not E: Compilation error. line int n3 = Calc.findMid(n1, n2); 

non-static method findMid(int,int) cannot be referenced from a static context
