If you want to create and run Java applications on your Windows 10 computer, you need to download and install JDK (Java Development Kit) 1.7. In this article, I will show you how to do that step by step. I will also explain what JDK is, what it is used for, and how to use it.
What is JDK 1.7?
JDK stands for Java Development Kit. It is a software package that contains tools and libraries for developing and testing Java programs. It includes a compiler (javac) that converts Java source code into bytecode, a runtime environment (JRE) that executes the bytecode, and other utilities such as archiver (jar) and documentation generator (javadoc).

JDK 1.7 is also known as Java SE (Standard Edition) 7. It was released in July 2011 and it introduced many new features and improvements, such as:
Project Coin: a set of small language changes that simplify coding, such as diamond operator, try-with-resources, multi-catch, etc.
Fork/Join Framework: a new framework for parallel programming that makes use of multiple cores.
NIO.2: a new API for file system operations that supports symbolic links, file attributes, etc.
InvokeDynamic: a new bytecode instruction that supports dynamic languages on the JVM.
G1 Garbage Collector: a new garbage collector that aims to reduce pause times and improve performance.
JDK 1.7 is still widely used by many developers and organizations because it is stable, compatible, and supported by Oracle until July 2022.

How to Download JDK 1.7?
To download JDK 1.7, you need to go to the Oracle Java SE 7 archive download page. There you will find different installers for different platforms and architectures. Since you are using Windows 10 64 bit, you need to select the Windows x64 installer: jdk-7u80-windows-x64.exe.
To download this file, you need to accept the license agreement and sign in with an Oracle account. If you don't have one, you can create one for free by clicking on the Create Account link. After signing in, you can click on the Download jdk-7u80-windows-x64.exe button and wait for the download to complete.
How to Install JDK 1.7?
To install JDK 1.7, you need to open the location of the downloaded executable and double-click on it. On Windows 10, you may see a User Account Control dialog box asking you to allow the app to make changes to your device. Click on Yes to proceed. Then, you will see the Java SE Development Kit 7 Setup wizard. Click on Next to continue.
On the next screen, you can choose the installation location for JDK 1.7. The default location is C:\Program Files\Java\jdk1.7.0_80. You can change it if you want, but make sure you remember it for later. Click on Next to continue.
On the next screen, you can choose whether to install the public JRE (Java Runtime Environment) or not. The public JRE is the one that is used by web browsers and other applications that require Java. If you already have a newer version of JRE installed, you can skip this step by unchecking the Public JRE option. Otherwise, you can leave it checked and choose the installation location for the public JRE. The default location is C:\Program Files\Java\jre7. Click on Next to continue.
On the next screen, you can see the installation progress and completion. Wait for the installation to finish and click on Close to exit the wizard.
How to Configure JDK 1.7?
To configure JDK 1.7, you need to set up an environment variable that points to the JDK installation directory. This will allow you to use JDK tools from any location on your computer. To do this, follow these steps:
Open the Control Panel and click on System and Security.
Click on System and then click on Advanced system settings on the left side.
Click on Environment Variables at the bottom of the System Properties window.
Under System variables, click on New to create a new variable.
Type JAVA_HOME as the variable name and type or browse to the JDK installation directory (e.g., C:\Program Files\Java\jdk1.7.0_80) as the variable value. Click on OK to save the variable.
Under System variables, find the variable named Path and click on Edit.
Add a semicolon (;) at the end of the existing value and then type %JAVA_HOME%\bin after it. This will add the JDK bin directory to the Path variable. Click on OK to save the changes.
Click on OK to close the Environment Variables window and click on OK again to close the System Properties window.
To check if JDK 1.7 is configured correctly, you can open a command prompt and type java -version and javac -version. You should see something like this:
C:\Users\user>java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode) C:\Users\user>javac -version javac 1.7.0_80
How to Use JDK 1.7?
To use JDK 1.7, you can create and run Java programs with any text editor or IDE (Integrated Development Environment) of your choice. For example, you can use Notepad or Notepad++ as a text editor and Eclipse or NetBeans as an IDE.
To create a simple Java program with Notepad, follow these steps:
Create a new text file and name it HelloWorld.java.
Type or copy-paste the following code into the file:
public class HelloWorld public static void main(String[] args) System.out.println("Hello, world!");
Save the file in any location on your computer (e.g., C:\Users\user\Desktop).
Open a command prompt and navigate to the location of the file (e.g., cd C:\Users\user\Desktop).
Type javac HelloWorld.java and press Enter to compile the file into bytecode.
Type java HelloWorld and press Enter to run the program.
You should see Hello, world! printed on the screen.
To use JDK 1.7 more effectively, you should learn how to use some of its tools and utilities that are available in the bin directory. Here is a table with some common JDK tools and their descriptions:

FAQs
Q: What is the difference between JDK and JRE?
A: JDK stands for Java Development Kit and JRE stands for Java Runtime Environment. JDK contains JRE plus the tools and libraries for developing and testing Java programs. JRE contains the JVM (Java Virtual Machine) and the core libraries for running Java programs. You need JDK if you want to create Java programs, and you need JRE if you want to run Java programs.
Q: How can I update JDK 1.7 to the latest version?
A: You can update JDK 1.7 to the latest version by downloading and installing the latest update from the Oracle Java SE 7 archive download page. The latest update as of June 2023 is JDK 1.7.0_80. You can also check for updates by using the Java Control Panel or the Java Update tool.
Q: How can I uninstall JDK 1.7 from Windows 10?
A: You can uninstall JDK 1.7 from Windows 10 by following these steps:
Open the Control Panel and click on Programs and Features.
Find Java SE Development Kit 7 Update 80 (or the version you have installed) and click on Uninstall.
Follow the instructions on the screen to complete the uninstallation process.
Delete the JDK installation directory (e.g., C:\Program Files\Java\jdk1.7.0_80) if it still exists.
Delete or modify the JAVA_HOME and Path environment variables if they still point to the JDK installation directory.
Q: How can I install multiple versions of JDK on Windows 10?
A: You can install multiple versions of JDK on Windows 10 by following these steps:
Download and install each version of JDK from the Oracle website, choosing different installation locations for each version (e.g., C:\Program Files\Java\jdk1.6.0_45, C:\Program Files\Java\jdk1.7.0_80, etc.).
Create a JAVA_HOME environment variable that points to the default JDK installation directory (e.g., C:\Program Files\Java\jdk1.7.0_80).
Add %JAVA_HOME%\bin to the Path environment variable.
Create additional environment variables for each version of JDK, such as JAVA_HOME_6, JAVA_HOME_7, etc., that point to their respective installation directories.
Use these variables to switch between different versions of JDK by changing the value of JAVA_HOME or using them in batch files or scripts.
Q: How can I check if JDK is working properly on Windows 10?
A: You can check if JDK is working properly on Windows 10 by creating and running a simple Java program, as explained in this article. You can also use some of the JDK tools, such as javac, java, jar, javadoc, etc., to test various aspects of JDK functionality. 44f88ac181
