Java中枚举类enum的values()方法举例详解

public enum EnumText {
    CODE_TYPE_ONE("春天",1),
    CODE_TYPE_TWO("夏天",2),
    ERROR("数据错误",-1)
    ;
    private String label;
    private Integer value;
    EnumText(String label, Integer value) {
        this.label = label;
        this.value = value;
    }
    public Integer getValue() {
        return value;
    }
    public String getLabel() {
        return label;
    }
}

public class Client {
    public static void main(String[] args) {
        for (EnumText e:EnumText.values()){
            System.out.println(e);
        }
        System.out.println("-------------------------------------");
        for (EnumText e:EnumText.values()){
            System.out.println(e.getLabel());
        }
        System.out.println("-------------------------------------");
        for (EnumText e:EnumText.values()){
            System.out.println(e.getValue());
        }
    }
}

//将.java文件编译
javac EnumText.java

//将编译成功后的.class文件反编译
javap -c EnumText.class >e.txt
