Hi friend,

Correct code you changes x[1] to x[0] and y[1] to y[0];


import java.io.*;
import java.util.*;
import java.math.*;

public class Add2Numbers{

public static void main(String args[])throws IOException{
int[] x=new int[1];
int[] y=new int[1];
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter first no.:");

x[0]=Integer.parseInt(in.readLine());

System.out.println("Enter second no.:");
y[0]=Integer.parseInt(in.readLine());

int s=x[0]+y[0];
System.out.println("Sum of two no. is:"+s);

}

}
