[jcubav]

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
2
