On Command Prompt I see the following

C:\Users\lek-h\Downloads\OOP>javac Example.java

C:\Users\lek-h\Downloads\OOP>

(i.e., no response from Command Prompt)

Java file

Under the following C:\Users\lek-h\Downloads\OOP\Example.java I have

class Example {
    // A Java program begins with a call to main().
    public static void main(String args[]) {
        System.out.println("Java drives the Web.");
    }
}

I have jdk 17 installed and set as path in system.

Under my system variables, I have System variable JAVA_HOME with value C:\Program Files\Java\jdk-17 System variable JAVA_PATH with value C:\Program Files\Java\jdk-17

Under user variables I have Variable Path with one value being %JAVA_HOME%\bin

    That's exactly what you should see if your code compiles successfully. Congratulations! There should be a file `Example.class` in your current directory. – tgdavies Oct 06 '21 at 03:22

You need to run two commands for running the java file.

  1. javac <filename.java>
  2. java < filename >

Run these commands on your command prompt:-

1) javac Example.java
2) java Example

Run these commands and check the output.

    Thanks for the response Harsh! I've tried the following and have not elicited any response. No Example.class was created, the println response was not shown in comand line either `1a. javac Example.java` `1b. java Example.java` `2a. javac Example` `2b. java Example` – anonymous_unagi Oct 07 '21 at 08:39
  • Try it once again. " javac filename.java" then type, " java filename". Or else check your path configuration. – Harsh Mendapara Oct 08 '21 at 05:26

    `You need to run two commands for the java file compilation.` - that's not accurate. First command will do `compilation`, second will start JVM with given arguments – rkosegi Oct 08 '21 at 05:26
  • Yes, you are right. The second command will start the java virtual machine. – Harsh Mendapara Oct 08 '21 at 05:29

You can directly run the program using the java command.

java Example.java
