getReturnType方法/getGenericReturnType方法都是获取Method对象表示的方法的返回类型，只不过前者返回的Class类型后者返回的Type(前面已分析过)，Type就是一个接口而已，在Java8中新增一个默认的方法实现，返回的就参数类型信息 publicinterfaceType{ //1.8新增defaultStringgetTypeName(){ returntoString();}} 而...
In the above example, we have created a string writer namedoutput. StringWriter output =newStringWriter(); We then use thewrite()method to write the string data to the string buffer. Note: We have used thetoString()method to get the output data from string buffer in string form. ...
