Could not run java bytecode on windows, compiled on mac

Question

I have written a simple java program on mac and compiled using javac option. To demonstrate it's platform independent, I copied the .class file to a windows machine (via email) and run java . However, it's giving error saying could not find or load main class...

I compared the java version on both mac and windows; both are same, except build version.

Below is the mac java version:

:~/Desktop/compare/javatest$ java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

Here is the simple java program:

public class Main {


    private int number1 = 0;


    public static void main(String[] args) {
        System.out.println("Hello World!");
    }

    void doSomething() {
        int number4=0;

        number4=number1+number1;

        int number2 =0;
    }
    int number3=0;
}

Attaching the error from windows machine

Maybe the current directory is not in the class path. Try adding it explicitly via tha `-cp .` flag. — Thilo, Jul 25 '19 at 03:19
Yes! adding the `-cp .` solved the issue. Thanks a lot! C:\Users\Admin\Downloads>java -cp . Main Hello World! — Suvro Choudhury, Jul 25 '19 at 03:37
' java -classpath ' worked for me. See if this helps.. https://stackoverflow.com/questions/18093928/what-does-could-not-find-or-load-main-class-mean — Immanuel, Jul 25 '19 at 03:37
