Java主类启动另一个主类

Question

I have two different java packages, one with a main class which calls another public class and then a second package which just has a main class. The issue is that I would like the package with one main class to call the main class in the other package to then initiate it. I tried doing it using the code below, but it obviously does not work as the two different classes aren't in the same package.

String[] args = {};
myMainClassNumber2.main(args);

Answer 1

You need to tell the compiler what package the other class is in.

Either

import your.pkg.myMainClassNumber2;

public static void main(String[] myArgs) {
  String[] args = {};
  myMainClassNumber2.main(args);
}

or

public static void main(String[] myArgs) {
  String[] args = {};
  your.pkg.myMainClassNumber2.main(args);
}
