How to Run Java Program in Notepad in Windows 7: Step by Step

Notepad on Windows 7 may be used to run Java apps with relative ease. Java code can be written and saved in Notepad since it is a text editor. This tutorial will show you how to compile and run Java code in Notepad on Windows 7 by providing you with a step-by-step guidance.

1. Installing the Java SE Development Kit (JDK)

Make sure the Java Development Kit (JDK) is installed on your Windows 7 PC before attempting to run any Java software. Get the latest version of the Java Development Kit (JDK) from Oracle’s website. To finish the JDK installation, run the installer and follow the on-screen instructions.

2. Crack up a notepad

Launch Notepad on Windows 7 to get started. Select “All Programs” from the menu that appears, then “Accessories,” and finally “Notepad.” When you click this, Notepad will open.

3. Create Your Own Java Programs

You may begin coding Java with Notepad. Java code may be entered into Notepad or copied and pasted. Make sure your code uses the correct Java grammar and structure. Be careful to define the main method properly and include any required import declarations.

4. Save Java File

Java code may be saved in Notepad by selecting “Save” from the “File” menu. Name your Java file something meaningful and easy to remember; just add the “.java” suffix. Choose a destination on your computer, such as the desktop or a particular folder, to save the file.

5. Launch the Command Prompt

You need to launch the Command Prompt in order to build and execute your Java code. To launch a command prompt, choose the Start menu and then enter “cmd” into the search box. A new window, named “Command Prompt,” will pop up.

6. Find Where You Installed Java

Use the “cd” command in the Command Prompt to go to the directory containing your Java program’s code. If the file is located in the current working directory, such as the desktop, enter “cd Desktop” and hit Enter. Using this command will transport you to your home directory.

7. Java Program Compilation

Use the Java compiler (javac) to build your Java application in the command prompt. To run a Java program, enter “javac” followed by Enter. Replace “filename” with the name of your Java program. Your code will be validated by the Java compiler before it is converted into a bytecode file.

8. Proceed to Start the Java App

Your Java application is ready to be executed when it has been compiled. In the command prompt, enter “java filename” followed by the Enter key, where “filename” is replaced with the name of your Java file (without the “.java” suffix).

Your Java program’s output will appear in the Command Prompt window once it has been executed by the Java Virtual Machine (JVM).
