An InterruptedException is a checked exception that is thrown when a thread is interrupted while it is waiting, sleeping, or performing some other blocking operation. This exception can be thrown when a thread is interrupted by another thread using the interrupt() method, or when a thread is interrupted by the Java Virtual Machine (JVM) to perform some shutdown operation.
To handle an InterruptedException, you can catch it using a try-catch block and take appropriate action in the catch block. For example:
try {
// code that may throw InterruptedException
} catch (InterruptedException e) {
// handle the exception
}
Alternatively, you can declare the exception in the throws clause of the method, in which case the calling method will be responsible for handling the exception. For example:
public void foo() throws InterruptedException {
// code that may throw InterruptedException
}
If you are receiving an error message stating that an InterruptedException is unhandled, it means that the exception is not being caught or declared in the appropriate place in your code. To fix this error, you will need to either catch the exception using a try-catch block or declare it in the throws clause of the method, depending on the context in which the exception is being thrown.
