Size in Java 20

In Java, the size of an array can be determined by using the length property. Here's an example code that demonstrates how to get the size of an array in Java:

public class ArraySizeExample {
   public static void main(String[] args) {
      int[] numbers = {10, 20, 30, 40, 50};
      System.out.println("Size of the array: " + numbers.length);
   }
}

In this example, an integer array called numbers is declared and assigned with 5 elements. The length property is used to get the size of the array, which is then printed using the System.out.println method.

Another example for getting the size of a String array:

public class StringArraySizeExample {
   public static void main(String[] args) {
      String[] names = {"John", "Jane", "James", "Jasmine"};
      System.out.println("Size of the array: " + names.length);
   }
}

In this example, a String array called names is declared and assigned with 4 elements. The length property is used to get the size of the array, which is then printed using the System.out.println method.
