本文深入讲解Servlet中响应对象的两种输出方式：字符输出与字节输出。探讨了使用resp.getWriter().write()进行字符输出和resp.getOutputStream().print()进行字节输出的区别及应用场景，强调了在实际开发中二者不可同时使用的原则。

         //响应对象常用方法
        //1.可以用作字符的输出
        resp.getWriter().write("啊");
        //2.用于字节输出
        resp.getOutputStream().print("哈哈");

这两个输出只写其中一个，不要两个写在一起
