Java Tutorial: End Program

This Java tutorial will teach you how to properly end a program. It is important to know how to end a program so that you can avoid data loss and other potential problems.

We’ll go over the different ways to end a program and when you should use each one. By the end of this tutorial, you’ll be able to end your programs correctly and confidently.

What is Java and why do we need to end it

Java is a programming language that allows for many different applications to be created. It is also used in a variety of devices, such as computers, phones, and ATMs.

Ending a Java program correctly is important so that all of the data associated with the program is saved correctly and no errors occur.

What are the consequences of not ending Java correctly

If you do not end your Java program correctly, you may lose data or cause other problems. For example, if you are working on a file in Java and do not save it before ending the program, you will lose your unsaved changes.

Additionally, improper termination of Java can lead to memory leaks. Memory leaks occur when parts of the memory are not properly freed up after they are no longer needed. This can eventually lead to the program crashing.

how to end program java

There are two ways to end a Java program: The first way is to use the System.exit() method. This method will cause the program to immediately stop running and exit. The second way is to use the System.out.println() method. This method will print out the text that is passed into it, but will not exit the program. Which method you use depends on what you want to happen after the program ends. If you want the program to completely stop running, then you would use System.exit(). However, if you just want to print out some text and continue running the program, then you would use System.out.println(). Let’s take a look at an example of each method.

System.exit() example

This example will use the System.exit() method to end the program.

    public static void main(String[] args) {

         // some code here



In this example, the program will stop running after the System.exit() method is called. The “0” that is passed into the method indicates that the program exited successfully. If there was an error, a different number would be passed in to indicate what kind of error occurred.

System.out.println() example

This example will use the System.out.println() method to print out some text and then continue running the program.

    public static void main(String[] args) {

         // some code here

         System.out.println(“End of program”);


In this example, the text “End of program” will be printed to the screen. The program will then continue running normally.

How to protect yourself from Java after you’ve ended it

Once you’ve ended your Java program, there are a few things you can do to help protect yourself and your data. First, make sure to save any changes you’ve made to your code. Next, if you’re using an IDE (Integrated Development Environment), make sure to close it completely. Finally, if you’re running the program from a command prompt, make sure to close the window when you’re finished.

Ending a Java program may seem like a simple task, but it’s important to do it correctly so that your data is saved and no errors occur. Now that you know how to properly end a Java program, you can confidently end your programs and avoid any potential problems.

Alternatives to Java that you can use instead

There are a few alternatives to Java that you can use instead. Some of these include:






Each of these languages has its own benefits and drawbacks, so be sure to do your research before deciding which one is right for you.
