Java技巧——少用枚举类型

Java技巧——少用枚举类型

少用枚举类型

public enum StatusCodeAndPhrase {
    OK("200 OK"),
    MovedPermanently("301 Moved Permanently"),
    BadRequest("400 Bad Request"),
    NotFound("404 Not Found"),
    VersionNotSupported("505 HTTP Version Not Supported");
    private String CodeAndPharse;
    StatusCodeAndPhrase(String CodeAndPharse)
    {
        this.CodeAndPharse = CodeAndPharse;
    }
    public String getCodeAndPharse()
    {
        return this.CodeAndPharse;
    }
}

多用静态变量

public class Status {
    public static final String OK = "200 OK";
    public static final String MOVED_PERMANENTLY = "301 Moved Permanently";
    public static final String BAD_REQUEST = "400 Bad Request";
    public static final String NOT_FOUND = "404 Not Found";
    public static final String HTTP_VERSION_NOT_SUPPORTED = "505 HTTP Version Not Supported";

原因：枚举类型调用的时候特别复杂！！！！
