Q1: 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] = new int[5][];
for (i = 0; i < x.length; i++)
{
for (j = 0; j < x[i].length; j++)
{
x[i][j] = new int [i + j + 1];
System.out.println('size = ' + x[i][j].length);
}
}
}
}
A 7
B 9
C 11
D 13
E Compilation fails
ANS:C - 11 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 = 7Therefore, 11 is the answer. |
