What is Java?
Java is a general-purpose, object-oriented, class-based programming language that was first released in 1995 by Sun Microsystems. One of the biggest reasons behind the popularity of Java is its platform independence which means a program written in java can run on several different types of machines.
In fact, Java promises “write once, run anywhere”. Java applications are compiled to bytecode that can run on any JVM (Java Virtual Machine) regardless of the architecture of a computer system.
The key features of Java are –
- Easy to learn and code
- Object-oriented programming language
- Platform independent
- Robust and secure language
- Highly portable
- High performance (Using its Just in time compiler)
- Supports multithreading
- Object-oriented programming support
- Functional Style
- Dynamic typing
- Platform Independent
- Interpreted Language or Just in time compiled
- Client-Side Validation
- Provides more control in the browser
The following table shows the key differences between Java and JavaScipt programming languages.
|Object oriented programming language||Object oriented scripting language|
|Strongly typed and has strict rules||Weakly typed and has more relaxed programming rules|
|It uses a thread based approach to concurrency||It has an event based approach to concurrency|
|Java supports multi-threading||It doesn't support multi-threading|
