Enum枚举类

入口类

public class xuleiTest {
    public static void main(String[] args) {
        String a = xuleiEnum.ONE.toString();
        String b = xuleiEnum.TWO.toString();
        String c = xuleiEnum.Three.toString();
        String d  = xuleiEnum2.ONE.toString();
        String e = xuleiEnum2.TWO.toString();
        System.out.println(a);
        System.out.println(b);
        System.out.println(c);
        System.out.println(d);
        System.out.println(e);
        
    }
}

不带参数的枚举类

public enum  xuleiEnum2 {
    ONE,TWO;
    private String name = "xulei";
    private String age = "12";
    
    @Override
    public String toString() {
        return this.name + "  "+ this.age;
    }
}

带参数的枚举类

public enum  xuleiEnum {
    ONE("one","1"){
    
    },TWO("tow","2"){
    
    },Three("three","3"){
    
    };
    xuleiEnum(String name,String age){
        this.age = age;
        this.name = name;
    }
    private String name = "xulei";
    private String age = "12";
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
    
    public void setAge(String age) {
        this.age = age;
    }
    
    public String getAge(){
        return age;
    }
    @Override
    public String toString() {
        return this.name + "  "+ this.age;
    }
}

输出结果

one  1
tow  2
three  3
xulei  12
xulei  12
