Hi

Running Java and JavaScript are two different tasks. Here’s how to do both on your Dell 620 with Windows 7:

So can you define your needs please.

1. Install Java Development Kit (JDK):

   • Download the JDK suitable for Windows 7 (e.g., JDK 14 or earlier) from Oracle or another trusted source.

   • Unzip or install the JDK to a directory, such as C:\Program Files\jdk-14.0.1

• Set Up Environment Variables:

  • Open Control Panel > System > Advanced system settings.

  • Click "Environment Variables".

  • Add a new system variable:

    • Variable name: JAVA_HOME

    • Variable value: C:\Program Files\jdk-14.0.1

  • Edit the Path variable and add: %JAVA_HOME%\bin

• Compile and Run Java Code:

  • Open Command Prompt (cmd).

  • Navigate to the folder containing your .java file.

  • Compile:
• text

  javac YourFile.java

• Run:
• text

  java YourFile

• For .jar files:
• text

  java -jar yourfile.jar

• If you want to run without a console window, use javaw instead of java

3. • .

• JavaScript is usually run inside a web browser.

• Open Internet Explorer, Chrome, or Firefox.

• If JavaScript is disabled, enable it via browser settings

• .

• You can run JavaScript in the browser console:

  • Press Ctrl+Shift+J in Chrome to open the console and type your JavaScript code
