Avoiding ClassCastException in Java: Best Practices and Code Examples

In Java, a Thread can be interrupted by another Thread to signal that it should stop what it’s doing. This interruption is accomplished by calling the interrupt method on the Thread that should be interrupted. When a Thread is interrupted, it may throw an InterruptedException. This post looks at this less common Java error and how it can be diagnosed and avoided.

An InterruptedException is a type of exception that occurs when a Thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted by another Thread. The interruption causes the Thread to throw an InterruptedException. This exception signals to the Thread that it should stop what it’s doing and exit.

How you can handle InterruptedException in a Java Thread:

public class MyThread extends Thread {
@Override
public void run() {
try {
// code that may throw InterruptedException
Thread.sleep(1000);
} catch (InterruptedException e) {
// handle InterruptedException
System.out.println("Thread was interrupted, exiting");
}
}
}public class Main {
public static void main(String[] args) {
MyThread myThread = new MyThread();
myThread.start();
myThread.interrupt();
}
}

In this example, MyThread extends the Thread class and overrides its run method. In the run method, we use the Thread.sleep(1000) method, which can throw an InterruptedException. The exception is caught in a try-catch block, and the message “Thread was interrupted, exiting” is printed to the console.

In the main method, we start an instance of MyThread. Then we interrupt the thread by calling myThread.interrupt(). If the thread is currently in a blocked state (e.g., sleeping), it will throw an InterruptedException, and the catch block will handle it.
