Question 18
Correct Answer:
The correct answer is C. The code in option C correctly iterates through all elements of the 2D array 'shirts' using a foreach loop and prints each element separated by a colon. The loops in options A, B, and D either do not access all elements in the correct order or result in an ArrayIndexOutOfBoundsException.

If D: ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2! the correct answer is C!

C is the correct one
[Removed]
Answer is C class HelloWorld { public static void main(String[] args) { String shirts[][] = new String[2][2]; //shirts[3][1] = "red"; //java.lang.ArrayIndexOutOfBoundsException shirts[0][0] = "red"; shirts[0][1] = "blue"; shirts[1][0] = "small"; shirts[1][1] = "medium"; for(String[] c : shirts){ //red:blue:small:medium: for(String s : c){ System.out.println(s + ":"); } } // for(int index = 0; index <= 2;){ //red: blue: java.lang.ArrayIndexOutOfBoundsException // for(int idx=0; idx<=2;){ // System.out.println(shirts[index][idx] + ":"); // idx++; // } // index++; // } } }

public static void main(String[] args) { String shirts[][] = new String[2][2]; shirts[0][0] = "red"; shirts[0][1] = "blue"; shirts[1][0] = "small"; shirts[1][1] = "medium"; /* A for (int index = 1; index < 2 ; index++) { for (int idx = 1; idx < index ; idx++) { System.out.print(shirts[index][idx] + ":" ); } } */ /* B for (int index = 0; index < 2 ; ++index) { for (int idx = 0; idx < index ; ++idx) { System.out.print(shirts[index][idx] + ":" ); } } */

/* C */ for (String [] c : shirts) { for (String s : c) { System.out.print(s + ":"); } } /* D System.out.println(); for (int index = 0; index <= 2; ) { for (int idx = 0; idx <= 2; ) { System.out.print(shirts[index][idx] + ":" ); idx++; } index++; } */ }

Tested, answer is only C. A and B, didnt print anything. D throws Exception (ArrayIndexOutOfBoundsException).
carloswork
Rewriting, A didn't print anything. B prints only "small:"
hhuo
Could anyone explain why B is not correct? I tested it, and it showed the exactly same result as C (red:blue:small:medium:).
carloswork
For me, B option returned only "small:"
anmoldev2java
for the first comparison where index = 0 and idx = 0 the condition idx < index will fail iteself.

only C D is incorrect: red:blue:Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
