方法“main()”没有签名“public static void main(String[])”。 main 出现这个问题时程序无法启动

Question

当尝试完成一个任务时（“创建一个包含两个String类型字段的Dog类：name和says。在方法中 main() 创建两个具有不同名称（spot 和 scruffy）和消息的 Dog 对象。 打印每个对象的两个字段的值”）项目无法启动。 程序本身：

public class Doges {

    String name;
    String says;

    public Doges(String name, String says) {
        this.name = name;
        this.says = says;
    }

    public static void main (String[] args) {

        Doges spot = new Doges ( "Spot","My name Spot bro, u know?");
        Doges scruffy = new Doges ("Scruffy","Yeah, i know man, but im - Scruffy and im Dog");

        System.out.println(STR."\{spot.name}: \{spot.says}");
        System.out.println(STR."\{scruffy.name}: \{scruffy.says}");
    }
}

我尝试交换课程，但这不是问题的原因。

为什么不做下面的事情

public class Doges {

    String name;
    String says;

    public Doges(String name, String says) {
        this.name = name;
        this.says = says;
    }

    public static void main (String[] args) {

        Doges spot = new Doges ( "Spot","My name Spot bro, u know?");
        Doges scruffy = new Doges ("Scruffy","Yeah, i know man, but im - Scruffy and im Dog");

        System.out.println(spot.name+" : "+spot.says);
        System.out.println(scruffy.name+" : "+scruffy.says);
    }
}
