How to Fix Unsupported major.minor Version 52.0 Error in Java

The unsupported major.minor version error is thrown in Java when a class is compiled using a higher version of the Java Development Kit (JDK) but executed on a lower version of the Java Runtime Environment (JRE). The exact cause is printed on the version e.g. in the case of major.minor version 52.0, the class is compiled using JDK 8 since major version 52 corresponds to Java SE 8. This error can usually be fixed by running the application on the same (or higher) JRE version as the JDK.

Handling the ArithmeticException Runtime Exception in Java

Arithmetic is at the core of every program and every programming language in existence. From integer and floating-point arithmetic all the way down to bitwise and pointer arithmetic, these mathematical operations translate into machine instructions which execute with thundering speeds and manipulate the state of software applications used across all sorts of different domains.

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 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.
