Edit: I understand what a NPE error is, I was struggling to find which part of my code was producing it.

I’m very new to java and a lot of the coding on here flies way over my head.
I’ve been trying to implement a very simple program that simply makes a stick figure jump when you click the canvas but it’s been throwing up a NullPointerException when attempting to click the canvas.

I fully understand that the functions and implementation I use below are far from optimal but I’m just trying to apply the very basics I’ve picked up, walking before flying and all that, and so whilst I’ll happily take advice on how to improve the general implementation what I’m really after is just how to solve the current error, thanks!.

import comp102x.Canvas; 
import comp102x.ColorImage; 
import java.awt.event.MouseListener; 
import java.awt.event.MouseEvent;

public class JumpMan implements MouseListener {
    private Canvas canvas;
    public ColorImage jumpMan;

    public JumpMan()
    {
        canvas = new Canvas();
        canvas.addMouseListener(this);
        ColorImage jumpMan = new ColorImage("jumpmanimg.png");
        canvas.add(jumpMan,200,200);
    }


    public void mouseClicked(MouseEvent click)
    {
        for (int i=1; i<=50; i++)
        {
            jumpMan.setY(jumpMan.getY()+1);
            pause(2);
        }
        for (int i=50; i>=0; i--)
        {
            jumpMan.setY(jumpMan.getY()-1);

Ряд пользователей (да и разработчиков) программных продуктов на языке Java могут столкнуться с ошибкой java.lang.nullpointerexception (сокращённо NPE), при возникновении которой запущенная программа прекращает свою работу. Обычно это связано с некорректно написанным телом какой-либо программы на Java, требуя от разработчиков соответствующих действий для исправления проблемы. В этом материале я расскажу, что это за ошибка, какова её специфика, а также поясню, как исправить ошибку java.lang.nullpointerexception.

Что это за ошибка java.lang.nullpointerexception

Появление данной ошибки знаменует собой ситуацию, при которой разработчик программы пытается вызвать метод по нулевой ссылке на объект. В тексте сообщения об ошибке система обычно указывает stack trace и номер строки, в которой возникла ошибка, по которым проблему будет легко отследить.

Что в отношении обычных пользователей, то появление ошибки java.lang.nullpointerexception у вас на ПК сигнализирует, что у вас что-то не так с функционалом пакетом Java на вашем компьютере, или что программа (или онлайн-приложение), работающие на Java, функционируют не совсем корректно. Если у вас возникает проблема, при которой Java апплет не загружен, рекомендую изучить материал по ссылке.

Как исправить ошибку java.lang.nullpointerexception

Как избавиться от ошибки java.lang.nullpointerexception? Способы борьбы с проблемой можно разделить на две основные группы – для пользователей и для разработчиков.

Для пользователей

Если вы встретились с данной ошибкой во время запуска (или работы) какой-либо программы (особенно это касается minecraft), то рекомендую выполнить следующее:

Переустановите пакет Java на своём компьютере. Скачать пакет можно, к примеру, вот отсюда;
Переустановите саму проблемную программу (или удалите проблемное обновление, если ошибка начала появляться после такового);
Напишите письмо в техническую поддержку программы (или ресурса) с подробным описанием проблемы и ждите ответа, возможно, разработчики скоро пофиксят баг.
Также, в случае проблем в работе игры Майнкрафт, некоторым пользователям помогло создание новой учётной записи с административными правами, и запуск игры от её имени.

Для разработчиков

Разработчикам стоит обратить внимание на следующее:

Вызывайте методы equals(), а также equalsIgnoreCase() в известной строке литерала, и избегайте вызова данных методов у неизвестного объекта;
Вместо toString() используйте valueOf() в ситуации, когда результат равнозначен;
Применяйте null-безопасные библиотеки и методы;
Старайтесь избегать возвращения null из метода, лучше возвращайте пустую коллекцию;
Применяйте аннотации @Nullable и @NotNull;
Не нужно лишней автоупаковки и автораспаковки в создаваемом вами коде, что приводит к созданию ненужных временных объектов;
Регламентируйте границы на уровне СУБД;
Правильно объявляйте соглашения о кодировании и выполняйте их.

Заключение

При устранении ошибки java.lang.nullpointerexception важно понимать, что данная проблема имеет программную основу, и мало коррелирует с ошибками ПК у обычного пользователя. В большинстве случаев необходимо непосредственное вмешательство разработчиков, способное исправить возникшую проблему и наладить работу программного продукта (или ресурса, на котором запущен сам продукт). В случае же, если ошибка возникла у обычного пользователя (довольно часто касается сбоев в работе игры Minecraft), рекомендуется установить свежий пакет Java на ПК, а также переустановить проблемную программу.
