Java之枚举类的基本用法

创建枚举类

package com.ywlaker.enums;

/**
 * @功能描述：季节枚举类
 * @author yang.wei
 * @time 2015年9月1日 上午11:56:23
 * @version 0.0.1
 */
public enum Season {
    SPRING("春天","spring"),
    SUMMER("夏天","summer"),
    AUTUMN("秋天","autumn"),
    WINTER("冬天","winter");
    private String index;
    private String name;
    private Season(String name, String index) {
        this.name = name;
        this.index = index;
    }
    public static String getName(String index) {
        for (Season s : Season.values()) {
            if (s.getIndex().equals(index)) return s.getName();
        }
        return null;
    }
    public String getIndex() {
        return index;
    }
    public void setIndex(String index) {
        this.index = index;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

遍历枚举类

public static String getName(String index) {
        for (Season s : Season.values()) {
            if (s.getIndex().equals(index)) return s.getName();
        }
        return null;
    }
