来个高手问个问题，Servlt 的。别说用过滤器..没学呢- -。
package com.jj;import java.io.IOException;

} --------------------编程问答-------------------- out.println("姓名="+username + "</br>");
out.println("密码="+password+ "</br>");
out.println("性别="+ sex);
第二段里 out.println("姓名")("密码")(“性别”)就这三个提交第二页会乱码。为什么呢？其他的都不乱啊？
--------------------编程问答-------------------- 代码格式化一下，就用那个#号图标。这看的，老乱了。 --------------------编程问答-------------------- 啊，没人....
补充：Java , Java EE
