Java is a class-based programming language. James Gosling developed this language for a Sun Microsystem project. Then in the later years, Oracle acquired the company. Initially named as "Oak" and later renamed it as Java. It is also a standalone multi-platform programming language. Java programs need a Java Development Kit. The JVM ( Java Virtual Machine) executes the codes and allows running these programs on any platform. Thus Java is referred to as "write once and run anywhere."
Developers use Java for building Android applications and enterprise software, integrating server-side technologies.
|An object-oriented programming language.
|An object-based scripting language.
|A compiled programming language. The java code is compiled into bytecode and then run on the JVM.
|An interpreted scripting language. The browser directly interprets the syntax of the code.
|A strongly typed language. Thus data types and variables must be declared.
|A loosely typed language. Thus data types are not declared, and variable declaration is flexible.
|Java applications can run on any virtual machine(JVM) or browser.
|Java is class-based and adopts a blueprint that includes properties and methods. Then Java derives objects from these classes.
|Java employs static type checking, checking variables at compile time.
|Java program uses more memory.
|Java maintains a thread-based approach to concurrency. Thus developers can work on multiple threads parallelly.
|Java supports multithreading allowing one to perform multiple tasks simultaneously.
|It has a file extension ".Java".
|It has file extension ".js"
|Java supports the Enum data type used in declaring a set of constants.
|Java's switch structure accepts only constants.
