From the middle of the 1990s, Java has been a well-liked general-purpose programming language. Sun Microsystems developed it; Oracle Corporation now owns it. Java is frequently employed in the software creation of desktop, web, mobile, and gaming applications.

Since Java is an object-oriented language, it is built around the idea of objects. Classes, which specify an object's behaviour and properties, are instances of which objects are instances. Java code can be executed on any platform that has a Java Virtual Machine (JVM) installed since it is a platform-independent language.

The automated memory management of Java is one of its important features. In Java, memory for objects does not need to be explicitly allocated or deallocated by the programmer.
