Can we catch InterruptedException?
If the blocking network call throws an InterruptedException your method can not finish computation in a normal way. You let the InterruptedException propagate. If no, then you should not declare your method with throws InterruptedException and you should (must!) catch the exception.
How do you fix InterruptedException?
Let’s take a look at them.
- 4.1. Propagate the InterruptedException. We can allow the InterruptedException to propagate up the call stack, for example, by adding a throws clause to each method in turn and letting the caller determine how to handle the interrupt.
- 4.2. Restore the Interrupt.
- 4.3. Custom Exception Handling.
What causes an InterruptedException?
Class InterruptedException. Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity. Occasionally a method may wish to test whether the current thread has been interrupted, and if so, to immediately throw this exception.
When you catch the InterruptedException into which state does it put the thread?
If any thread is in sleeping or waiting state (i.e. sleep() or wait() is invoked), calling the interrupt() method on the thread, breaks out the sleeping or waiting state throwing InterruptedException.
Why sleep method throws InterruptedException?
sleep() method throws InterruptedException if a thread in sleep is interrupted by other threads. InterruptedException is a checked type of exception. sleep()” statement must be enclosed within try-catch blocks or it must be specified with throws clause.
Is InterruptedException a checked exception?
Since InterruptedException is a checked exception that is checked by the compiler itself for the smooth execution of the program at runtime, therefore, we got a compilation error at compile-time and InterruptedException exception at runtime.
Is InterruptedException checked?
What happens when InterruptedException is thrown?
Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity. Occasionally a method may wish to test whether the current thread has been interrupted, and if so, to immediately throw this exception.
What is an InterruptedException?
java.lang.InterruptedException. Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity. Occasionally a method may wish to test whether the current thread has been interrupted, and if so, to immediately throw this exception.
What is throws InterruptedException in Java?
Why InterruptedException is a checked exception?
With InterruptedException being checked, the worst case is that the exception is caught, but in a way that isn’t awfully useful. (Actually the absolute worst case is the interrupt flag is not restored, leaving any following code in the thread unaware that the interruption happened.)
When is an InterruptedException thrown in Java?
The InterruptedException is thrown when a thread is waiting or sleeping and another thread interrupts it using the interrupt method in class Thread. So if you catch this exception, it means that the thread has been interrupted.
What happens when a thread is interrupted in Java?
In this state, a thread is waiting for a signal from another thread. When a thread either finishes execution or terminates abnormally, it’ll wind up in the TERMINATED state. Threads can be interrupted, and when a thread is interrupted, it will throw InterruptedException.
What to do when network call throws InterruptedException?
Example: Your method waits for a value from the network to finish the computation and return a result. If the blocking network call throws an InterruptedExceptionyour method can not finish computation in a normal way. You let the InterruptedExceptionpropagate. int computeSum(Server server) throws InterruptedException {
Is the InterruptedException a permanent source of pain in Java?
InterruptedException is a permanent source of pain in Java, for junior developers especially. But it shouldn’t be. It’s a rather simple and easy-to-understand idea. Let me try to describe and simplify it.
