ATM java problem

**import java.io.*;
class work
{
public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int X;double Y;
X=Integer.parseInt(br.readLine());
Y=Double.parseDouble(br.readLine());
if(X%5==0&&X<=Y)
{
double d=Y-(X+.50);
System.out.println(d);
}
else
System.out.println(Y);
}
}

RUN TIME ERROR IS SHOWN WIT THE MASSEGE NECZ OR SOME THING LIKE THIS .PLZ POINT OUT THE ERROR AND DESCRIBE PLEASE

using bufferedReader sometimes causes problems when you have to take input simultaneously.
use split(" ").

import java.io.*;
class work
{
public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int X;double Y;
String[] ar = br.readLine().split(" ");
X=Integer.parseInt(ar[0]);
Y=Double.parseDouble(ar[1]);
if(X%5==0&&X<=Y)
{
double d=Y-(X+.50);
System.out.println(d);
}
else
System.out.println(Y);
}
}

I checked your last solution, import java.io.*; was missing.

After adding this line, the compilation error was removed. Then it showed Wrong answer.

This was due to the condition if(X%5==0&&X<=Y)

Correction: if(x%5==0&&X+0.5<=Y) ,[ this because 0.5 is also to be deducted from the balance]
Here is the corrected solution link: CodeChef: Practical coding for everyone

import java.util.Scanner;
import java.io.*;

class Transaction{

public void transaction(int amount, double balance)
{
	double interest = 0.50;
	if(amount+interest<=balance && amount%5==0)
	{
		
		
			amount += interest;
			double d = balance-amount;
			System.out.println(d);
	}
	else{
			System.out.println("Incorrect Withdrawl amount: "+balance);
		}
}

}

class ATM {
public static void main(String[] args) throws IOException
{
Transaction trn = new Transaction();
double balance;
int amount;
// System.out.println("Enter amount you want to withdrawl: " +"Main Balance is: "+balance);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

	String[] ar = br.readLine().split(" ");
	amount = Integer.parseInt(ar[0]);
	balance = Double.parseDouble(ar[1]);
	 trn.transaction(amount, balance);
}

}

not working

Here Is My Answer Which Is Accepted
My Answer On Code Chef, Click On This To See On Codechef

public class ATM {
    public static void main(String[] args) {
        Scanner scin = new Scanner(System.in);
        int withdraw = scin.nextInt();
        double balance = scin.nextDouble();
        if(withdraw+0.50<=balance&&withdraw%5==0){
            balance=balance-withdraw-0.50;
        }
        System.out.println(balance);
    }
}

And The Error You Are Facing Because:
NZEC is a runtime error . It mostly occurs when negative array index is accesed or the program which we have written takes up more space than the allocated memory for our program to run

What To Do When You Face This Problem In Future?

Ans:

  1. Surround Your Code With Try Catch It Will Resolve NZEC Error
  2. Try To Clean Your Code Space Complexity
    Example Below: 
public class ATM {
    public static void main(String[] args) {
        try{
             Scanner scin = new Scanner(System.in);
             int withdraw = scin.nextInt();
             double balance = scin.nextDouble();
             if(withdraw+0.50<=balance&&withdraw%5==0){
                balance=balance-withdraw-0.50;
             }
            System.out.println(balance);
        }
        catch(Exeption e){
            System.out.println(e);
        }
    }
}
