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; 

Test.doPrint(); 

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

COJ? 

A. int i = 0; 

for (String[] sub: arr) { 

int j = sub.length -1; 

for (String str: sub) { 

System.out.println(str[j]); 

i++; 

B. private static void doPrint() { 

for (int i = 0;i < arr.length;i++) { 

int j = arr[i].length-1; 

System.out.print(arr[i][j]); 

C. int i = 0; 

for (String[] sub: arr[][]) { 

int j = sub.length; 

System.out.print(arr[i][j]); 

i++; 

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

int j = arr[i].length-1; 

System.out.print(arr[i][j]); 

i++; 

Answer:

Explanation: 

Incorrect: 

not A: The following line causes a compile error:

Q70. Given: 

public class ColorTest { 

public static void main(String[] args) { 

String[] colors = {"red", "blue","green","yellow","maroon","cyan"}; 

int count = 0; 

for (String c : colors) { 

if (count >= 4) { 

break; 

else { 

continue; 

if (c.length() >= 4) { 

colors[count] = c.substring(0,3); 

count++; 

System.out.println(colors[count]); 

What is the result? 

A. Yellow 

B. Maroon 

C. Compilation fails 

D. A StringIndexOutOfBoundsException is thrown at runtime. 

Answer:

Explanation: The line, if (c.length() >= 4) {, is never reached. This causes a compilation error. 

Note: The continue statement skips the current iteration of a for, while , or do-while loop. An unlabeled.break.statement terminates the innermost.switch,.for,.while, or.do-while.statement, but a labeled.break.terminates an outer statement.
