how to handle no such element exception in java

I am new to java programming , and i am trying to learn the usage of classes and objects in java programming , while writing the following code i got an exception


for sample input


1 2 3 4 5

here first line contains number of elements (in this case its 5),and next line contains elements.

while taking input inside the for loop in the class Election ,i am getting exception.

I tried searching on stack Overflow, and other resources too,but still can't figure out how to remove this exception.

import java.util.Scanner;
public class TestClass {
     public static void main(String[] args) {
        int n;
        Scanner input = new Scanner(;
        n = input.nextInt();
        Election obj = new Election(n);
class Election {
     int n,v1,v2,v3,v4,v5,d;
     public Election(int n) {
          this.n = n;
     public void getVotes() {
       Scanner sc = new Scanner(;
       for(int i = 0 ; i < 1 ; i++) {
         int var = sc.nextInt();
         switch(var) {
             case 1: ++v1; break;
             case 2: ++v2; break;
             case 3: ++v3; break;
             case 4: ++v4; break;
             case 5: ++v5; break;
           default: ++d; break;

Looks like I'm a bit late, but since your accepted answer is more of comment rather than a solution, I'll post this anyway.

Here is a simple deviation of the code you provided, but reaches the desired result!

I'll walk you through this:

public class MyTest {
    public static void main(String[] args) {

        //First of all, we need an instance of an Election-type object, so
        //that we can call its methods and get votes from users.
        Election e = new Election();
        //Now we can easily call the method getVotes(), as defined in Election class.
        //What happens here, is that the program will 'jump' to the getVotes() method
        //and it will execute every line of code in that method. Then it will
        //'return' to where it 'left off' in the main() method. Since getVotes()
        //is of type 'void', it will not return anything. It will just 'jump' back.

        //Now, you can use testResult() method, to see the values of the variables.

Now, let's take a look at the class Election and how it works.

public class Election {
    private final int VOTES_NUM = 1;
    private int v1,v2,v3,v4,v5,d;

    public Election() {
        //print now, just to show that all variables = 0

    //Simple method that prints value of each variable. We use this for testing
    public void testResult(){
        System.out.println("v1 = "+v1);
        System.out.println("v2 = "+v2);
        System.out.println("v3 = "+v3);
        System.out.println("v4 = "+v4);
        System.out.println("v5 = "+v5);
        System.out.println("d = "+d);

    private int getInput(){
       //First of all, we need a Scanner to take user input. 
       //You do that in your own code too. We simply move it in this method instead.
        Scanner input = new Scanner(;

        //You also need variable to hold the user input. 
        //(Always give meaningful names to all entities)
        int userInput;

        System.out.print("Please enter vote number here: ");

        //the next part has to be in a try-catch block, 
        //to avoid exceptions like InputMismatchException, etc..
            //Get user input
            userInput = input.nextInt();
        //If user enters letter, or symbol, or something else that isn't an integer,
        //then inform them of the mistake they made and recursively call this method,
        //until they get it right!
        catch (InputMismatchException ime){
            System.out.println("Please enter only a single number");
            return getInput();

        //If all goes well, return the user input
        return userInput;

    public void getVotes() {
        //'VOTES_NUM' is a constant that defines the times the 
        //loop will iterate (like Macros in 'C')
        for(int x=0; x<VOTES_NUM; x++)
            int n = getInput();
        //then let the switch statement increment one of the variables
        switch(userInput) {
            case 1: ++v1; break;
            case 2: ++v2; break;
            case 3: ++v3; break;
            case 4: ++v4; break;
            case 5: ++v5; break;
            default: ++d; break;

No Such Element Exception while scanning multiple inputs, Looks like I'm a bit late, but since your accepted answer is more of comment rather than a solution, I'll post this anyway. Here is a simple  How to check if an ExecutionResult is empty in Neo4j. java,neo4j. An execution result is essentially an iterator of a map, its type definition is something like: Iterable<Map<String,Object>> So you can easily just do: result.iterator().hasNext(); I think that its strictly a ResourceIterator, so if you get an iterator you are supposed to close it if you don't exhaust it.

I think the code that you posted is missing. The code you posted is working properly and I achieved to get exception only when I wrote input.close() before the obj.getVotes(). When you want to close scanners you should do this after code finishes. Thus, if you close input after the obj.getVotes() you shouldn't get any error.

What is causing this NoSuchElementException? (Beginning Java , Score = -1. Exception in thread "main" java.util. NoSuchElementException will be throwed because the you are tring to read the data from the input (Scanner) where data is reached to the end. So you have to read the input( Does this mean that Scanner tries to read past the end of the file multiple times? Our journey continues through our in-depth Java Exception Handling series as, today, we dig into the depths of the NoSuchElementException.As the name suggests, a NoSuchElementException is thrown when trying to access an invalid element using a few built-in methods from the Enumeration and Iterator classes.

I tried running your code in a short main class, and I am not getting any exception. This is how I ran your method:

public static  void main(String...args){
    Election election = new Election(10);

My input was 1 2 3 4 5 6 7 1 2 2 and the console output was:

2 // v1
3 // v2
1 // v3
1 // v4
1 // v5
2 // d

I did make a small change to your program. In the for loop inside the getVotes() method, I changed the condition to i<n (instead of i<1 in your posted code)

NoSuchElementException for nextInt - general, JAVA yells when it doesn't get required inputs… 2 Likes. vangari May 29 Scanner input = new Scanner(;. a=input.nextInt();. b=input.nextInt(); Exception in thread “main” java.util.NoSuchElementException at java.util.​Scanner. NoSuchElementException will be throwed because the you are tring to read the data from the input (Scanner) where data is reached to the end. So you have to read the input( Scanner ) by checking hasNext() is true or false

java.util.NoSuchElementException: No line found (Look around , NoSuchElementException: No line found (Look around line 1540). While I can succesfully run my code and pass the 'pseudo-tests' in IntelliJ locally, It seems to be related to using scanner for user input. 2. The user is then prompted for each word that has been double underscored. a. The error, java.util.NoSuchElementException is often thrown in the context of a Scanner when you call nextLine () and there's no next line. You can cover this by checking for a next line before asking for it.

How to resolve the "java.util.NoSuchElementException" in Java, is to check whether the next position of an iterable is filled or empty. You should only move to this position if the check returns that the position is not empty. The following methods are used to check the next position: hasNext() So the game has to run multiple times. My problem is, the Scanner only works in the first loop and then throws an exception the second time (on int wager=scan.nextInt();)! How can I get the Scanner to contnue taking inputs?

How to solve java.util.NoSuchElementException in Java, How do you handle no such element exception in Java? I use hasNextLine method to check,scanning from won't block on Linux,but used it windows work well.whether it has any other method to block in Linux. 11-27-2013, 02:21 AM lzw
