Java is also a set of several computer software and specifications developed by Sun Micro systems, later acquired by Oracle Corporation, that provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers.
Java software is used to write any application and it can also run on different computing environment without modification.
Installation and Configuration of Java Development Kit (JDK) | Java Software
After installing the JDK on your system, you need to configure the java software so that it will be recognized by the system. Use the following step to configure the JDK:
- Open my computer on the desktop
- Double click on C:/
- Go to program files and open Java folder
- Open the Java Development Kit folder
- Open Bin
- Copy the directory from the address bar
- Go to control panel and select system
- Click on Advance System setting
- Click Environment Variebles
- Under system variables, locate path and click edith
- Put a semicolon at the end of the statement there
- Then paste the directory that you copied
- Click OK
Having done this, You are now Good to Go and write any Application in Java
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. The platform is not specific to any one processor or operating system, rather an execution engine (called a virtual machine) and a compiler with a set of libraries are implemented for various hardware and operating systems so that Java programs can run identically on all of them.
There are multiple platforms, each targeting a different class of devices
- Java Card: A technology that allows small Java-based applications (applets) to be run securely on smart cards and similar small-memory devices.
- Java ME (Micro Edition): Specifies several different sets of libraries (known as profiles) for devices with limited storage, display, and power capacities. Often used to develop applications for mobile devices, PDAs, TV set-top boxes, and printers.
- Java SE (Standard Edition): For general-purpose use on desktop PCs, servers and similar devices.
- Java EE (Enterprise Edition): Java SE plus various APIs useful for multi-tier client–server enterprise applications.
