link to question: https://www.codechef.com/problems/HS08TEST

Code:

    /* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;
import java.text.DecimalFormat;
/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
    public static void main (String[] args) throws java.lang.Exception
    {
        Scanner input = new Scanner(System.in); 
        int numberOne = input.nextInt();
        float numberTwo = input.nextFloat();
        float reduction = 0;
        float result = 0;
        DecimalFormat df2 = new DecimalFormat(".00");
        if(numberOne > 0 && numberOne <= 2000 & numberTwo >= 0 && numberTwo <= 2000){
        if(numberOne % 5 == 0){
            reduction = (float)numberOne+(0.50f);
            if(reduction <= numberTwo){
                result = numberTwo-reduction;

                System.out.println(df2.format(result));
            }
            if(reduction > numberTwo){
                System.out.println(df2.format(numberTwo));
            }
        }
        else{
            System.out.println(df2.format(numberTwo));
        }
        }

    }

}

Error:

Exception in thread "main" java.util.NoSuchElementException at java.util.Scanner.throwFor(Scanner.java:862) at java.util.Scanner.next(Scanner.java:1485) at java.util.Scanner.nextInt(Scanner.java:2117) at java.util.Scanner.nextInt(Scanner.java:2076) at Codechef.main(Main.java:14)

V_for_Vj :

A simple thing worked for me .... i only surrounded the code by try and catch....

final working code...

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
    public static void main (String[] args) throws java.lang.Exception
    {
        try{
        int n, sum = 0;
        Scanner s = new Scanner(System.in);
        n = s.nextInt();
        int a[] = new int[n];
        for(int i = 0; i < n; i++)
        {
            a[i] = s.nextInt();
        }

        int largest=0;
        int element=0;


        for(int i = 0; i < n; i++){
            for(int j=0;j<n;j++){
                element=a[i]%a[j];
                if(largest<element){
                    largest=element;
                }
            }
        }
        System.out.println(largest);
    }
            catch(Exception e){

    }
    }
