[project topics]

Code:

import java.io.*;
class Arraysum
{
int temp;
      int sum(int a[],int n)
      {
            if(n==1)
                  return a[0];
            else
        {
                  temp =sum(a,n-1);
                   temp=temp+a[n-1];
                   return temp;
        }
       }
}
class Newarray
{
public static void main(String args[])throws IOException
{
DataInputStream dis=new DataInputStream(System.in);
          System.out.println("Enter limit");
         int n=Integer.parseInt(dis.readLine());
         int a[]=new int[10];
         System.out.println("Enter the array");
    

for(int i=0;i<n;i++)
         {  
             a[i]=Integer.parseInt(dis.readLine());
         }
         Arraysum a1=new Arraysum();
         System.out.println("Array sum is"+ a1.sum(a,n));
}
}

OUTPUT
E:\5BCA-B\lijo\java>java Newarray
Enter limit
3
Enter the array
