Can't run Hello World java program on Windows

Question

public class Main {
    public static void main(String[] args) {
        //Set your print into the console
        System.out.println("Hello World");
    }
}

I have tried executing the program through command prompt(cmd.exe), yet it keeps on bringing errors as its output.

I expected to get hello World, but I get:

Error: could not find or load main class MyClass.java

`Error: could not find or load main class MyClass.java` The name is wrong in two respects. 1) Your class is called `Main`, not `MyClass`. 2) The JVM launches a `.class` file, not the `.java` source code file. — Andrew Thompson, Jun 03 '19 at 03:30

Since you gave little to no information it's hard to tell where the error is.

Here's the code which would print 'Hello World'

public class Main {
    //Class name is irrelevent, but it must be the same as the filename

    //Define a main method, it HAS to be public, static and called 'main' and should     
    //receive a String array and return void (just copy the next row)
    public static void main(String[] args) {
        //Set your print into the console
        System.out.println("Hello World");
    }

}

Now compile your file by typing in the terminal:

javac <the path to your .java file>

And then:

java <classname (here Main)>

Could you try posting it again? Also do you use a package? – VoroX Jun 02 '19 at 21:46
Please how can post my code for it has detected as not code format. – Donfortune Jun 02 '19 at 21:57
Place four spaces before each line - there's an instruction at the top of the text area where you write your post. – VoroX Jun 02 '19 at 22:02
It writes" You can only post once in 90mins" – Donfortune Jun 02 '19 at 22:12
