The Java JDK (Java Development Kit) is a software development environment that creates Java applications. It includes tools and libraries that enable developers to write, compile, and execute Java code. It also provides a platform-independent runtime environment called the Java Virtual Machine (JVM), which allows Java code to run on any platform that supports the JVM.
The Java JDK is necessary for developing and running Java applications. It includes the most commonly used version of Java SE (Standard Edition) Development Kit. The Java SE Development Kit consists of the Java compiler, tools for creating and managing JAR (Java Archive) files, and tools for managing and monitoring the JVM.
Checking System Requirements
Before downloading and installing Java JDK on Windows 10, ensure that your system requirements are as mentioned below so that it may run smoothly:
- Operating System: Windows 10 (64-bit)
- Disk Space: At least 400 MB of free disk space
- RAM: At least 2 GB of RAM
- Processor: Intel Pentium 4 or higher with a clock speed of 2 GHz or higher
It is important to note that the JDK requires a 64-bit version of Windows 10. If you are not sure whether your system is 32-bit or 64-bit, you can check by following these steps:
- Click the Windows Start button and select Settings (gear icon).
- Click on "System."
- Click on "About."
- Look for the system type information under the device specifications section.
If your system is 32-bit, you must install the 32-bit version of Java JDK, which can be downloaded from the Oracle website.
Downloading the Java JDK Installer
To download the installer for Windows 10, follow these steps:
- Open a web browser and go to the Oracle Java SE Downloads page at https://www.oracle.com/java/technologies/javase-downloads.html.
- Scroll to the Java SE section and click the "JDK Download" button.
- Accept the license agreement by clicking the radio button next to "Accept License Agreement."
- Select the appropriate JDK version for your system. Choose the version that matches your operating system (e.g., Windows x64 for 64-bit Windows 10).
- Click the download link next to the version you want to download.
- The download should start automatically. If not, click the download link again to start the download.
Once the download is complete, you will have the installer file saved on your computer. The installer file name typically ends with ".exe."
Installing Java JDK on Windows 10
To install it on Windows 10, follow these steps:
- Double-click on the Java JDK installer file that you downloaded.
- If prompted, click "Yes" to allow the installer to change your device.
- The installer will open. Click "Next" to start the installation process.
- Choose the installation location, leave the default location, and click "Next."
- The installer will ask you to select the components you want to install. Leave the default selections and click "Next."
- On the next screen, the installer will ask you to specify a location for installing the Java Runtime Environment (JRE). Leave the default location and click "Next."
- Click "Install" to begin the installation process.
- Once the installation is complete, click "Close" to exit the installer.
The JDK is now installed on your Windows 10 system. By default, the installation directory is usually "C:\Program Files\Java\jdk-version."
About the latest JDK Version
In March 2023, Oracle released Java JDK 20, the most recent version of the most widely used programming language and development platform. The release includes thousands of performance, stability, and security improvements and platform enhancements that can help developers improve productivity and drive innovation and growth across their organizations.
The most significant updates in Java 20 include enhancements to Record Patterns and Pattern Matching for Switch. This helps increase developer productivity by allowing users to nest record patterns and type patterns to create a robust, declarative, and composable form of data navigation and processing.
Virtual Threads, a new feature of Project Loom, significantly streamlines the writing, maintaining, and observing high-throughput concurrent applications by introducing lightweight virtual threads to the Java Platform.
Additionally, the Foreign Function & Memory API and Vector API features of Project Panama enable Java programs to interoperate with code and data outside of the Java runtime, increasing ease of use, performance, and safety.
