java - 程序未针对 Java 进行编译，我缺少什么

Question

package freshjuice;


class FreshJuice {

    enum FreshJuiceSize { SMALL, MEDIUM, LARGE }
        FreshJuiceSize size;
    }


}

public class FreshJuiceTest {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        FreshJuice juice = new FreshJuice();
        juice.size = FreshJuice.FreshJuiceSize.MEDIUM ;
        System.out.println("Size: " + juice.size);
        // TODO code application logic here
    }

}

这是我收到的错误消息:

Error: Main method not found in class freshjuice.FreshJuice, please define the main method as:
   public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application

Answer 1

您的文件必须名为 FreshJuiceTest.java，因为这是您的 main 方法所在的类。
