Hi Friend,

Try this:

import java.util.*;
class  Triangle
{
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.print("Enter edge1: ");
        int e1=input.nextInt();
        System.out.print("Enter edge2: ");
        int e2=input.nextInt();
        System.out.print("Enter edge3: ");
        int e3=input.nextInt();
        int n=e1+e2;
        boolean check=false;
        if(e3==n){
          check=true;
        }
        else{
            check=false;
        }
        System.out.println("can edges "+e1+","+e2+" and "+e3+" from a triangle? "+check);
    }
}

Thanks
