JAVA毕业设计

叮叮小文库JAVA课程设计专业班级: 姓 名: 学 号: 24152400472 指导老师: 一设计背景电子相册是现在时下很流行的一种网络元素，它可以应用于很多的领域。其以静态照片为素材，配合动感的背景、字幕等视频处理的特殊效果，配上音乐就可制作成电子相册。制作好的电子相册可以在电脑上，各类影碟机上，以及手机和MP4里都能观看。当然，如果考虑到长期保存的话，也可以保存在硬盘上，也便于随时调阅、欣赏，永久保存。二需求分析1.采用的形式为：java application2.需要实现的主要功能是：（1）不同用户的登录模块（2）附加背景音乐。三概要设计3.1功能说明该程序可以实现用户登录、放大、缩小、上一张、下一张、播放照片等功能。3.3 主要的工具包该程序中用到如下几个工具包，为：import java.awt.Dimension;import java.awt.Toolkit;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JOptionPane;import javax.swing.JPasswordField;import javax.swing.JTextField;import java.awt.*;import javax.swing.*;import java.io.*;import java.awt.event.*;import java.applet.AudioClip; import java.applet.Applet;import java.awt.Frame; import .MalformedURLException; import .URI;import .URL;。四系统功能模块结构该电子相册程序分为登录相关模块、背景音乐播放模块、相册相关模块这3个模块。五系统实现 import java.awt.Dimension;import java.awt.Toolkit;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JOptionPane;import javax.swing.JPasswordField;import javax.swing.JTextField;import java.awt.*;import javax.swing.*;import java.io.*;import java.awt.event.*;import java.applet.AudioClip;
