Process finished with exit code 0 java

When a Java program finishes executing without any errors, it usually terminates with an exit code of 0. This exit code signifies that the program executed successfully without any issues.

The exit code is a way for the program to communicate its status to the operating system or any other application that called it. By convention, an exit code of 0 indicates success, while non-zero codes indicate different types of errors or failures.

Here’s an example to illustrate how the exit code works in Java:

    
      public class ExitCodeExample {
          public static void main(String[] args) {
              // Perform some tasks
      
              // Exiting with exit code 0 indicates success
              System.exit(0);
          }
      }
    
  

In this example, the program performs some tasks, and then calls the System.exit(0) method to terminate with an exit code of 0. This indicates that the program executed successfully.

It’s important to note that the System.exit() method can also be used to explicitly indicate an error or failure. In such cases, a non-zero exit code is used to represent different types of errors or failures. For example:

    
      public class ExitCodeExample {
          public static void main(String[] args) {
              // Perform some tasks
      
              // Exiting with a non-zero exit code indicating an error
              System.exit(1);
          }
      }
    
  

In this modified example, the program still performs some tasks, but now calls System.exit(1) to indicate an error or failure. The exit code of 1 signifies that the program encountered an issue during execution.
