t1.setBounds(120,40,80,20);// 设置文本框java系统设计附源代码的初始位置

this.add(t1);// 将文本框组件添加到容器

password.setBounds(50,100,60,20);//密码标签java系统设计附源代码的初始位置

this.add(password);//将密码标签组件添加到容器

t2.setBounds(120,100,80,20);//设置密码标签的初始位置

this.add(t2);//将密码标签组件添加到容器

b1.setBounds(50,150,60,20);//设置登陆按钮的初始位置

this.add(b1);//将登陆按钮组件添加到容器

b2.setBounds(120,150,60,20);//设置取消按钮的初始位置

this.add(b2);// 将取消按钮组件添加到容器

b1.addActionListener(this);//给登陆按钮添加监听器

b2.addActionListener(this);// 给取消按钮添加监听器

this.setVisible(true);//设置窗口的可见性

this.setSize(300,200);//设置窗口的大小

addWindowListener(new WindowAdapter()

{

public void windowClosing(WindowEvent e)

{

System.exit(0);

}

});//通过内部类重写关闭窗体的方法

}

public void actionPerformed(ActionEvent e)

{

if(e.getSource()==b1)//处理登陆事件

{

String name=t1.getText();

String pass=t2.getText();

if(name!=nullpass.equals("000123"))//判断语句

{

new StudentJieMian();

}

}

}

public static void main(String args[])//主函数

{

new DengLuJieMian();

}

}

以下方法实现了学生界面设计

import java.awt.*;

import java.awt.event.*;

class StudentJieMian extends Frame implements ActionListener

{

MenuBar m=new MenuBar();//创建菜单栏

Menu m1=new Menu("信息");//创建菜单“信息”

MenuItem m11=new MenuItem("插入");//创建“插入”的菜单项

MenuItem m12=new MenuItem("查询");

Menu m2=new Menu("成绩");//创建菜单“成绩”

MenuItem m21=new MenuItem("查询");

public StudentJieMian()

{

this.setTitle("学生界面");//设置窗口标题

this.setLayout(new CardLayout());//设置窗口布局管理器

this.setMenuBar(m);//将菜单栏组件添加到容器

m.add(m1);//将信息菜单放入菜单栏

m.add(m2);

m1.add(m11);//将“插入”菜单项添加到“信息”菜单

m1.add(m12); //将“查询”菜单项添加到“信息”菜单

m2.add(m21); //将“查询”菜单项添加到“成绩”菜单

m11.addActionListener(this); //给“插入”菜单项添加监听器

m12.addActionListener(this); //给“查询”菜单项添加监听器

m21.addActionListener(this); //给“查询”菜单项添加监听器

this.setVisible(true); //设置窗口的可见性

this.setSize(300,200); //设置窗口的大小

addWindowListener(new WindowAdapter()

{

public void windowClosing(WindowEvent e)

{

System.exit(0);//关闭窗口

}

});

}

public void actionPerformed(ActionEvent e)

{

if(e.getSource()==m11) //处理“添加信息”事件

{

new AddStudent();

}

if(e.getSource()==m12) //处理“查询信息”事件

{

new SelectStudent();

}

if(e.getSource()==m21) //处理“查询成绩”事件

{

new ChengJiStudent();

}

}

public static void main(String args[])

{ new StudentJieMian(); //创建一个对象 }

Q5: 用java编写的商品库存管理系统的设计思路以及源代码是什么？

既然是商品库存系统，那么最少有各种商品的单件信息，1：需要有商品的进货价格，卖出价格，剩余数量，每月的销售数量，进货时间等，在对应的数据库表创建相应的字段。2：商品管理就是对多种商品的管理，所以还要有各种商品的分类，比如烟酒类，饮料类，小吃类，将其分类好管理，同样数据库里面建立相对的数据表。具体需要根据自己需求来编写。3:界面的设计，这里可分为登陆界面，其中一个是用户登陆后查看的界面，和管理员登陆后查看的界面，用户登录只能查看对应的商店的物品管理，并且能进行修改自家商品。管理员登陆可查看所有的用户的商店物品，及修改物品信息。而物品分类栏就可以用jQuery来实现局部的刷新界面。左边为物品分类栏，右边为选中物品类的信息。点击右边分类物品的某件物品，可跳转到该类物品的单个信息，如第1点提到的。
