How many lines of output will the following program produce?
public class Test {
public static void main(String[] args) {
int[][][] num = new int[3][][];
int i, j;
num[0] = new int[4][];
num[1] = new int[2][];
num[2] = new int[5][];
for (i = 0; i < num.length; i++) {
for (j = 0; j < num[i].length; j++) {
num[i][j] = new int[i + j + 1];
System.out.println("size = " + num[i][j].length);
}
}
}
}
