Display sum of the series 1/(1+2) + 1/(1+2+3) + 1/(1+2+3+4) + …. n terms

This is a BlueJ Program on series. This program involves nested loop.

import java.util.*;

class Search

{

    int i,j;

    double sum=0;

    int x,n;

    Scanner sc=new Scanner(System.in);

public void display()

{

     System.out.print("\nEnter Value of 'n': ");

     n=sc.nextInt();

    for(int i=0;i< n;i++)

    {

        x=0;

       for(j=1;j< =i+2;j++)

      

       {

           x=x+j;

       }

       sum=sum + 1.0/x;

    }

    System.out.println("\nSum of the series: "+sum);

}

      

    public static void main(String args[])

    {

        Search ob=new Search();

        ob.display();

   }

 }
