Question 1

What will be the output of the program? public class CommandArgs 
{
    public static void main(String [] args) 
    {
        String s1 = args[1];
        String s2 = args[2];
        String s3 = args[3];
        String s4 = args[4];
        System…

Accepted Answer

An exception is thrown because in the code String s4 = args[4];, the array index (the fifth element) is out of bounds. The exception thrown is the cleverly named ArrayIndexOutOfBoundsException.

Question 2

In the given program, how many lines of output will be produced? public class Test 
{
    public static void main(String [] args) 
    {
    int [] [] [] x = new int [3] [] [];
    int i, j;
    x[0] = new int[4][];
    x[1] = new int[2][];
    x[2]…

Accepted Answer

The loops use the array sizes (length). It produces 11 lines of output as given below. D:\Java>javac Test.java

D:\Java>java Test
size = 1
size = 2
size = 3
size = 4
size = 2
size = 3
size = 3
size = 4
size = 5
size = 6
size = 7 Therefore, 11 is the answer.
