Java之枚举举例

package enumdemo;

/**
 * 枚举类
 */

public enum MAPPER {

    // 实例
    ELEMENT_NAME("mapper"),
    ATTRIBUTE_RESOURCE("resource");

    private String content;

    MAPPER(String content) {
        this.content = content;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }
}

package enumdemo;

/**
 * 枚举测试
 */
public class Test {
    public static void main(String[] args) {
        String content = "";
        content = MAPPER.ATTRIBUTE_RESOURCE.getContent();
        System.out.println(content);

        String content2 = MAPPER.valueOf("ELEMENT_NAME").getContent();
        System.out.println(content2);

        for (MAPPER mapper : MAPPER.values()) {
            System.out.println(mapper.getContent());
        }
    }
}

运行结果：

resource
mapper
mapper
resource
