关于java:java枚举案例

public enum TypeEnum {    /**     * 类型1     */    T1(1, "类型1"),    T2(2, "类型2"),    T3(3, "类型3");    private final Integer value;    private final String name;    TypeEnum(Integer value, String name) {        this.value = value;        this.name = name;    }    public String getName() {        return this.name;    }    public Integer getValue() {        return this.value;    }}public class Demo {    public static void main(String[] args) {        System.out.println( TypeEnum.T2.getValue());        //        2        System.out.println( TypeEnum.T2.getName());        //        类型2    }}
