我有一个 Java 问题 - 它没有找到一些 package 或类

Question

I create just a test over here to try to see what is the problem. But I am very new to Java, Any advice will be much appreciated.

My goal is to make my Main class to call the method from the second class.

Main Class code:

package Constructors;

public class Main {

    public static void main(String[] args) {

        test testObject = new test();
        testObject.message();

    }
}

---

Second Class code:

package Constructors;

public class test {

    public void message() {
        System.out.println("Please Work!");
    }
}

Error msg:

Answer 1

There can be only one public class in java file, create another file for test class and then try to run it
