How to Handle the InterruptedException Checked Exception in Java

Threads are a basic concept in concurrent and parallel programming . They allow programs to do multiple things at the same time and are often used for performing computationally intensive tasks in the background without interrupting the main program. This is accomplished through multithreading, a common programming and execution model which allows multiple threads to exist within the context of one process. These threads share resources but are able to execute independently.

How to Fix The IllegalStateException in Java

An IllegalStateException is a runtime exception in Java that is thrown to indicate that a method has been invoked at the wrong time. This exception is used to signal that a method is called at an illegal or inappropriate time. For example, once a thread has been started, it is not allowed to restart the same thread again. If such an operation is performed, the IllegalStateException is thrown.

How to Handle the Illegal Monitor State Exception in Java

An IllegalMonitorStateException is a runtime exception in Java that occurs in multithreaded applications. It indicates that the calling thread has attempted to wait on an object's monitor, or attempted to notify other threads waiting on an object's monitor, without owning the specified monitor. Since the IllegalMonitorStateException is an unchecked exception, it does not need to be declared in the throws clause of a method or constructor.

How to Handle the Unsupported Class Version Runtime Error in Java

Runtime errors occur when a program is being executed and, in the case of compiled languages, after the program has been successfully compiled. Runtime errors are, therefore, harder to detect and prevent than compile-time errors . This allows for a certain category of errors to be captured and dealt with before the program effectively starts.
