how to run java in notepad++
To run Java in Notepad++, you first need to ensure that you have Java Development Kit (JDK) installed on your system. Once you have JDK installed, you can write your Java code in Notepad++, save the file with a .java extension, open the command prompt, navigate to the directory where your Java file is saved, and compile it using the javac command. If there are no errors during compilation, you can run your Java program using the java command followed by the name of the main class. You can also customize Notepad++ to compile and run Java programs directly from the editor by setting up custom build commands in the Run menu.
