java - 如何在java中使用for或while方法调用枚举？

Question

所以我尝试使用 for 或 while 方法来打印主方法中的所有对象。(Anna，Courtney，Ashley)

         public class JavaApplication56 {

        public enum details {

    Anna(" blue ", " blue"),
    Courtney(" red", " black"),
    Ashley(" yellow ", " green");

    String hairColor;
    String eyeColor;

    details(String hairColor, String eyeColor) {

        this.hairColor = hairColor;
        this.eyeColor = eyeColor;
    }

    public String getHair() {
        return hairColor;

    }

    public String getEye() {


        return eyeColor;
    }
}

我在主要方法下收到错误，指出二元运算符的操作数类型错误。 第一个类型为 int，第二个类型为details[]。

public static void main(String[] args) {

    JavaApplication56 ja = new JavaApplication56();

    for (int person = 0; person < details.values(); person++) {

        System.out.println(details.values()+details.);
    }

}
}

Answer 1

或更简单地说:

// details should be re-named Details
for (Details detail : Details.values()) {
  System.out.println(detail); // does it have a toString() override?
}
