D. double y1 = 203.22; floatflt = y1 

E. int y2 = 100; 

floatflt = (float) y2; 


Q112. Given the code fragment: 

What is the result?

Q113. Given: 

public class Marklist { 

int num; 

public static void graceMarks(Marklist obj4) { 

obj4.num += 10; 

public static void main(String[] args) { 

MarkList obj1 = new MarkList(); 

MarkList obj2 = obj1; 

MarkList obj1 = null; 

obj2.num = 60; 


How many objects are created in the memory runtime? 

A. 1 

B. 2 

C. 3 

D. 4 


Explanation: obj1 and obj3. 

when you do e2 = e1 you're copying object references – you're not making a copy of the object – and so the variables e1 and e2 will both point to the same object. 

Q114. Which two are Java Exception classes?

Q115. Given the code fragment: 

public class Test { 

static String[][] arr =new String[3][]; 

private static void doPrint() { 

//insert code here 

public static void main(String[] args) { 

String[] class1 = {"A","B","C"}; 

String[] class2 = {"L","M","N","O"}; 

String[] class3 = {"I","J"}; 

arr[0] = class1; 

arr[1] = class2; 

arr[2] = class3; 


Which code fragment, when inserted at line //insert code here, enables the code to print 


A. int i = 0; 

for (String[] sub: arr) { 

int j = sub.length -1; 

for (String str: sub) { 



B. private static void doPrint() { 

for (int i = 0;i < arr.length;i++) { 

int j = arr[i].length-1; 


C. int i = 0; 

for (String[] sub: arr[][]) { 

int j = sub.length; 



D. for (int i = 0;i < arr.length-1;i++) { 

int j = arr[i].length-1; 






not A: The following line causes a compile error: 


Not C: Compile erro line:
