       else{

       }
        }
    }
}

Can anyone tell me why I’m getting NZEC error in it??

You should at least give link to problem statement so that it easier to answer. Nobody is going to read your code without any hint of the question.

3

See your class name!
public class in Java needs to be named as Main !

NZEC occurs when a program doesn’t have a return statement(for c users) or your program throws an exception!

4

Its http://www.codechef.com/problems/TLG but i’ve solved this problem in C & C++, I’m getting NZEC error in JAVA even though i’ve thrown all the exceptions

5

That i have also seen in FAQs, but i’ve thrown all the exceptions still i’m getting NZEC

import java.util.ArrayList;

    	n=sc.nextInt();
    	ArrayList<Main> round=new ArrayList<Main>();
    	for(int i=0;i<n;i++)
    	{
    		Main r=new Main();
    		r.setPlayer1(sc.nextInt());
    		r.setPlayer2(sc.nextInt());
    		round.add(r);
    	}

       int player1=round.get(i).getPlayer1();
       int player2=round.get(i).getPlayer2();
       if(player1>player2){
           round.get(i).setlead(player1-player2);
           round.get(i).setLeader("Player1");
       }else{
              round.get(i).setlead(player2-player1);
           round.get(i).setLeader("Player2");
       }
   }
   String player=round.get(0).getLeader();
   int max=round.get(0).getLead();
   for(int i=1;i<n;i++){
       if(max<round.get(i).getLead()){
           max=round.get(i).getLead();
           player=round.get(i).getLeader();
       }
   }
   if(player.equals("Player1")){
       System.out.println("1 "+max);
   }
   else{
       System.out.println("2 "+max);
   }
sc.close();    
}

}

There were several problems with your code, which I noticed only after reading the problem statement.
I edited your code! You were taking input t, whereas you don’t need t in this sum. Moreover your integer parsing was also wrong!

The code now gives wrong answer indicating a logical error!
