java枚举自定义属性及方法例子

 枚举enum 的全称为 enumeration， 是 JDK 1.5  中引入的新特性，存放在 java.lang 包中。

枚举定义类：

package enums;public enum SexEnum {Man("Tom"){public String sayInfo(){return getName();}},Woman("Lily"){public String sayInfo(){return getName();}};private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}private SexEnum(String name){this.name = name;}public abstract String sayInfo();}

枚举测试类：

package enums;/** * 枚举测试类 * @author LD * */public class EnumTest {public static void main(String[] args) throws Exception {testEnum(SexEnum.Man);testEnum(SexEnum.Woman);}private static void testEnum(SexEnum sex) {switch (sex) {case Man:System.out.println("This is a man,"+sex.Man.sayInfo());break;case Woman:System.out.println("This is a woman,"+sex.Woman.sayInfo());break;default:System.err.println("I don't known your sex");break;}}}

结果：

This is a man,Tom
This is a woman,Lily
