The compiled byte code is platform-independent, and we can run it on any machine irrespective of the Operating system.Ħ. Platform-Independent: Java provides a guarantee that to write code once and run it anywhere(at any platform). Moreover, Java contains a security manager that defines the access levels of Java classes.ĥ. All Java programs run in the virtual machine. Secure: Java is a secure language, as Java does not use explicit pointers. Features like Exception handling and garbage collection make Java robust or strong.Ĥ. Java uses a garbage collector to provide a strong memory management system. Robust: Java always tries to check errors at runtime and compile time.

A Java program must have at least one class and object.ģ. In other words, it has some data and behavior.

Object-Oriented: Everything in Java is in the form of the object. For example, the use of explicit pointers and operator overloading are not in Java.Ģ. Java eliminates many complex and ambiguous concepts of C++. Simple: Java is simple because its syntax is simple and easy to understand. Java Micro Edition (ME): We use this edition to develop applications for small devices such as set-top boxes, phones, and appliances, etc. Java Enterprise Edition (EE): We use this edition to create large programs that run on the server and to manage heavy traffic and complex transactions.ģ. Java Standard Editions (SE): We use this edition to create programs for a desktop computer.Ģ. Each Java edition has different capabilities. Java follows the WORA (Write Once, Run Anywhere) principle, and is platform-independent. Java is freely accessible to users, and we can run it on all the platforms. It is designed for the distributed environment of the Internet. Java is the most widely used programming language.

In 2009, Oracle Corporation took over Sun Microsystem. Sun Microsystem changed the name to Java in 1995. It was developed by James Gosling at Sun Microsystems in 1991. Java programming language is a high-level, object-oriented, general-purpose, and secure programming language.
