What is Java programming used for?
The Java programming language was developed by Sun Microsystems in the early 1990s. Although it is primarily used for Internet-based applications, Java is a simple, efficient, general-purpose language. Java was originally designed for embedded network applications running on multiple platforms.
What is Java and why do I need it?
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable.
What is Java with example?

What is Java and how it works?
High-Level Languages and Computer Code To achieve its goal of “Write once, run anywhere,” Java does both: a Java compiler converts Java code into machine-readable bytecode, then the Java Virtual Machine interprets the code for the computer it runs on.
Does Windows 10 need Java?

What are the basics of Java?
Java – Basic Syntax
- Object − Objects have states and behaviors.
- Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type supports.
- Methods − A method is basically a behavior.
- Instance Variables − Each object has its unique set of instance variables.
Is Java hard to learn?
