Program to Calculate the Length of Array

Here is a Java Program to demonstrates the length array member.

class Length {
  public static void main(String args[]) {
    int a1[] = new int[10];
    int a2[] = {3, 5, 7, 1, 8, 99, 44, -10};
    int a3[] = {4, 3, 2, 1};

    System.out.println("length of a1 is " + a1.length);
    System.out.println("length of a2 is " + a2.length);
    System.out.println("length of a3 is " + a3.length);
  }
}

Output of Above Java Program
length of a1 is 10
length of a2 is 8
length of a3 is 4
