What Is Java?

What Is Java?


Java is a  high level(also object-oriented)  programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. 

The Java syntax is similar to C++ but is strictly an object-oriented programming language. For example, most Java programs contain classes, which are used to define objects, and methods, which are assigned to individual classes. Java is also known for being more strict than C++, meaning variables and functions must be explicitly defined. This means Java source code may produce errors or "exceptions" more easily than other languages, but it also limits other types of errors that may be caused by undefined variables or unassigned types.

What is core and advanced Java?
Core Java is used for developing general java application whereas Advanced java is used for developing the web-based application and enterprise application. Core java is having the concept of Java Fundamentals, Applet, Swings, JDBC, JavaBeans.... technology without this no one can jump on any advance java technology.
