What is the Java equivalent of PHP's die function?

System.exit(0); // Terminates the Java program gracefully

In PHP, the `die()` function is used to terminate script execution. It can also optionally output a message before stopping the execution. In Java, while there's no direct equivalent to `die()`, you can achieve similar behavior by using `System.exit(int status)`, which stops the JVM and exits the application with a specified status code.

try {
    // Your code logic here...
    if (someConditionFails) {
        System.exit(1); // Exit with an error
    }
} catch (Exception e) {
    e.printStackTrace();
    System.exit(1); // Exit after logging the error
}

Causes

• Runtime errors that necessitate termination of the program.
• Validating input or conditions where further execution is unnecessary.

Solutions

• Use `System.exit(0)` for graceful termination without any error, or `System.exit(1)` to indicate an abnormal termination.
• Implement exceptions and graceful error handling instead of immediate termination, which allows for cleanup operations before exiting.

Mistake: Using `System.exit()` in a Multi-threaded Environment.

Solution: Be cautious when terminating an application running multiple threads since `System.exit()` stops all threads immediately.

Mistake: Exiting without cleanup.

Solution: Ensure to close resources, files, or database connections if necessary before exiting.
