package arrays;

public class ArrayDefaultValues {

   
    public static void main(String[] args) {
          int a[];
          a=new int[3];
          System.out.println("a value is"+a);
          int sum=0;
          for (int i=0;i<a.length ;i++ )
          {
              System.out.println("\t"+a[i]);
              sum=sum+a[i];
          }
          System.out.println("the sum of elements is"+sum);

    }

}

output:
