1、JAVA学生管理系统 JAVA学生管理系统编译提示(1)有使用其他可视化Java编程工具经验的用户也可以利用这些软件已经携带的JDK。例如从“控制面板”中通过【系统】|【高级】|【环境变量】，针对JBuilder8设置环境变量，即把Path路径设置为C:JBuilder8jdk1.4bin，然后将每章“源程序”目录之中的内容保存在例如C:temp目录中，然后即可在命令提示符窗口中切换到C:temp并使用javac classpath . *.java命令进行编译(其中-classpath用来告诉编译器用户Java文件的路径，“ . ”表示*.java文件的路径在当前目录位置，注意点的前后均有一

2、个空格)。经过编译产生*.class文件后，在C:temp提示符下使用java classpath . * 命令即可运行程序(其中-classpath用来告诉编译器用户类文件的路径，“ . ”表示*.class文件的路径在当前目录位置，注意点的前后均有一个空格。“*”为不包括扩展名的类文件名)。(2)上述方法对于直接安装的JDK 1.5亦完全适用。(3)也可以象书中介绍的那样，在使用javac命令之前使用set classpath=c:temp设置类路径(等号前后不能有空格)，然后即可直接使用javac *.java编译命令和java *运行命令。(4)但是应注意，在使用JDK 1.4时，个别

3、程序可能会无法正常编译运行(因JDK 1.5的编程方式略有变化)。所以应首选JDK 1.5。(5)与在“环境变量”对话框中设置类路径相比，在命令提示符窗口中设置类路径是比较稳妥的方法。因为用户存放程序代码的目录位置是根据内容不同而随时确定的。此外您可能会发现“环境变量”对话框中的ClassPath设置在有些情况下毫无作用。AddCourseInfo.javaimport java.awt.event.*;import java.awt.*;import javax.swing.*;/* 课程信息管理模块* 添加新的课程信息*/public class AddCourseInfo extends
