正例: http 1.1 中,s-maxage 告诉服务器进行缓存,时间单位为秒,用法如下, response.setHeader("Cache-Control", "s-maxage=" + cacheSeconds); 12. 【推荐】 服务端返回的数据,使用 JSON 格式而非 XML。 说明: 尽管 HTTP 支持使用不同的输出格式,例如纯文本,JSON,CSV,XML,RSS 甚至 HTML。如果我 ...
String objects that are promoted to an old heap region before this age has been reached are always considered candidates for deduplication. The default value for this option is 3. See the -XX:+UseStringDeduplication option. -XX:SurvivorRatio=ratio Sets the ratio between eden space size and su...

return "person : "+age; } 3,Class getClass():获取任意对象运行时的所属字节码文件对象。 4,int hashCode():返回该对象的哈希码值。支持此方法是为了提高哈希表的性能。 通常equals,toString,hashCode,在应用中都会被复写,建立具体对象的特有的内容。
