Who will Dominate in the future: .Net or Java?

With the ongoing release of new technologies in the IT market, your choices for programming languages is also changing. This makes the task of choosing one among all the languages a tough job. Java and.Net are two renowned languages that have been involved in a locked horn competition for years. Since both languages offer unique benefits, opting for one is itself a brainstorming tussle.

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.

How to Fix the Unsupported Operation Exception Error in Java

An UnsupportedOperationException is a runtime exception in Java that occurs when a requested operation is not supported. For example, if an unmodifiable List is attempted to be modified by adding or removing elements, an UnsupportedOperationException is thrown. This is one of the common exceptions that occur when working with Java collections such as List, Queue, Set and Map. The UnsupportedOperationException is a member of the Java Collections Framework.

How to Handle the Incompatible Types Error in Java

Variables are memory containers used to store information. In Java, every variable has a data type and stores a value of that type. Data types, or types for short, are divided into two categories: primitive and non-primitive. There are eight primitive types in Java: byte, short, int, long, float, double, boolean and char. These built-in types describe variables that store single values of a predefined format and size.

Java Guides: How to Handle the Unclosed String Literal Error

Strings are a fundamental data type in most modern general-purpose programming languages. In Java, strings are defined as character sequences and are represented as immutable objects of the class java.lang.String which contains various constructors and methods for creating and manipulating strings . Below is an example of the string literal "rollbar" being assigned to two different variables a and b which both reference the same (automatically interned) String object.

What Is Log4Shell? The Log4j Vulnerability Explained

A new vulnerability that impacts devices and applications that use Java has been identified in Log4j, the open-source Apache logging library. Known as Log4Shell, the flaw is the most significant security vulnerability currently on the internet, with a severity score of 10-out-of-10. Fortunately, Perforce static analysis and SAST tools — Helix QAC and Klocwork — can help.
