Install Java JDK in Windows 8, 10 & 11 – Tech Mirrors

The purpose of Install JDK (Java Development Kit) is to provide the tools necessary for developing and running Java applications. It includes the Java compiler, which compiles source code into bytecode that can be executed on a Java Virtual Machine (JVM), as well as other tools such as the debugger, documentation generator, and jar file packaging tool.

Developers use JDK to create Java applications, applets, and servlets. It is also used for writing Java-based web services, developing Android apps, and building Java-based desktop applications. The JDK is a platform-independent software development kit, which means that it can be used on any operating system that supports Java.

In addition to the Java programming language, JDK also includes libraries and tools for developing applications in other programming languages such as JavaScript, Python, and Ruby, using the Java Virtual Machine (JVM).

Prerequisites to install Java JDK

To install Java JDK on your system, you need to make sure you meet the following prerequisites:

1. Operating System: You can install Java JDK on a variety of operating systems, including Windows, Linux, and macOS.
2. System Requirements: Ensure your system meets the minimum requirements for running Java JDK, which are typically:
   • 2 GB of RAM
   • 1 GB of free disk space
   • 2 GHz processor or faster
   • Internet connection
3. Download the JDK: You can download the JDK from the official Oracle website. Ensure that you download the correct version of the JDK for your operating system.
4. Set the Path: After installing the JDK, you need to set the PATH environment variable to point to the JDK installation directory. This is required to run Java programs from the command prompt.
5. Verify the installation: Once you have installed and configured the JDK, you can verify it by running the “java -version” command in a command prompt or terminal window. This should display the version of the JDK that you have installed.

By meeting these prerequisites, you should be able to successfully install and configure the Java JDK on your system.
