JAVA设计GUI登陆界面上，有修改密码的Button,对于修改密码的源代码？
你肯定用数据库了吧，过程很简单啊，就是把你修改以后的值覆盖到数据库中就行了。不过覆盖前最后检验一下新密码是否合法
用Java设计一个登录页面，不用连接数据库，只要把用户和密码信息存放在文本里面，怎样设计代码？？？

你修改一下吧，从记事本获得用户名判断一下就行了
用jsp java做一个修改登录密码,有下面的代码
首先，form表单必须的，是用来输入用户名和密码，brform表单 action="%=basePath %Admin.shtml" method="post",br主要指明的是请求的路径，请求的方式，post.bronSubmit="return checkPWD()"的目的就是在点击提交的时候执行的操作，。br成功的话就跳转到action所指定的路径去。不成功的话就是还在当前页。br/HEADbr%brString message = (String)request.getAttribute("message");brif(message == null){brmessage = "";br}brif (!message.trim().equals("")){brout.println("script language='javascript'");brout.println("alert('"+message+"');");brout.println("/script");br}brrequest.removeAttribute("message");br%br%brString username=(String)session.getAttribute("user");brif(username==null){brresponse.sendRedirect(basePath+"/error.jsp");br}brelse{brList list=(List)session.getAttribute("list");br%br从session里面获取userName的值，然后就是判断，如果是空的话就跳转到错误的页面，还有如果请求的信息如果有的话就弹出请求的信息的内容！！！
java 修改登陆密码 代码
你这个登陆程序哪来的修改按钮啊,只有确定和退出两个按钮嘛.
你这登陆用户名是:sdd 密码是:123 而且要程序中已经定死了.这一句:if ((name.equals("sdd")) (passWord.equals("123")))说的.
你如果想添加一个修改用户名和密码的按钮就必须用一个另外的文件进行保存,当然用数据库就更好了.而你这个没必要改,因为没有永久存贮的文件,即使你改了密码,当你下次再运行时密码又被重新初始化了.
JAVA中怎么更改密码?如下代码.求帮忙调试.实现功能4修改密码的功能
你要想让程序记住你的修改结果是不可能的，应为你只要退出这个程序，所有的变量都就被清理了。当你再次重新运行程序时，所有的变量又被从新初始化赋值。你要想验证你的密码是不是被修改就得找那个保存文件的代码。将你的修改结果保存起来。要不然你是看不到结果的。。或者你就把你的那些写入到数据库中。然后在查询数据库。
你要是想修改本程序的。你这个程序中的密码是123.、那你就弄个输入程序。然后这个123替换掉不就行了嘛。if (name1.equals("xiaoming") pwd1.equals("123")) 。如果你是想让显示出来。当完成String p = scan.next();这句后，你把p的值就得到了。打印出来就可以了啊
