Arrays length
Array size, arrayName.length, holds its length. The following code outputs the length of each
array by using its length property.
public class Main {
public static void main(String args[]) {
int a1[] = new int[10];
int a2[] = {1, 2, 3, 4, 5};
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);
}
}
This program displays the following output:
length of a1 is 10
length of a2 is 5
length of a3 is 4
