本文实例为大家分享了java gui管理系统的具体代码,供大家参考,具体内容如下
1.先完成主页面mainui(代码如下)
package com.pag_1; import javax.swing.*; import java.awt.*; import java.awt.event.actionevent; import java.awt.event.actionlistener; public class mainui extends jframe implements actionlistener { //定义组件 jbutton jb1,jb2,jb3=null; jradiobutton jrb1,jrb2=null; jpanel jp1,jp2,jp3,jp4=null; jtextfield jtf=null; jlabel jlb1,jlb2,jlb3=null; jpasswordfield jpf=null; buttongroup bg=null; //设定用户名和密码 final string stu_name="王小明"; final string stu_pwd="1"; final string stu_num="14140301"; final string tea_name="王老师"; final string tea_pwd="1"; final string tea_num="00001"; public static void main(string[] args) { mainui mui=new mainui(); } public mainui() { //创建组件 jb1=new jbutton("登录"); jb2=new jbutton("重置"); jb3=new jbutton("退出"); //设置监听 jb1.addactionlistener(this); jb2.addactionlistener(this); jb3.addactionlistener(this); jrb1=new jradiobutton("教师"); jrb2=new jradiobutton("学生"); bg=new buttongroup(); bg.add(jrb1); bg.add(jrb2); jrb2.setselected(true); //初始页面默认选择权限为 学生 jp1=new jpanel(); jp2=new jpanel(); jp3=new jpanel(); jp4=new jpanel(); jlb1=new jlabel("用户名:"); jlb2=new jlabel("密 码:"); jlb3=new jlabel("权 限:"); jtf=new jtextfield(10); jpf=new jpasswordfield(10); //加入到jpanel中 jp1.add(jlb1); jp1.add(jtf); jp2.add(jlb2); jp2.add(jpf); jp3.add(jlb3); //添加标签 jp3.add(jrb1); jp3.add(jrb2); jp4.add(jb1); //添加按钮 jp4.add(jb2); jp4.add(jb3); //加入jframe中 this.add(jp1); this.add(jp2); this.add(jp3); this.add(jp4); this.setlayout(new gridlayout(4,1)); //选择gridlayout布局管理器 this.settitle("学生成绩管理系统"); this.setsize(300,200); this.setlocation(400, 200); this.setdefaultcloseoperation(jframe.exit_on_close); //设置当关闭窗口时,保证jvm也退出 this.setvisible(true); this.setresizable(true); } public void actionperformed(actionevent e) { //事件判断 if(e.getactioncommand()=="登录") { //如果选中教师登录 if(jrb1.isselected()) { tealogin(); //连接到教师的方法 页面 }else if(jrb2.isselected()) //学生在登录系统 { stulogin(); //连接到学生的方法 页面 } }else if(e.getactioncommand()=="重置") { clear(); } } //学生登录判断方法 public void stulogin() { if(stu_name.equals(jtf.gettext())&&stu_pwd.equals(jpf.gettext())) { joptionpane.showmessagedialog(null,"登录成功!","提示消息",joptionpane.warning_message); dispose(); clear(); stdui ui=new stdui(); //创建新界面 }else if(jtf.gettext().isempty()&&jpf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入用户名和密码!","提示消息",joptionpane.warning_message); }else if(jtf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入用户名!","提示消息",joptionpane.warning_message); }else if(jpf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入密码!","提示消息",joptionpane.warning_message); }else { joptionpane.showmessagedialog(null,"用户名或者密码错误!\n请重新输入","提示消息",joptionpane.error_message); //清空输入框 clear(); } } //教师登录判断方法 public void tealogin() { if(tea_name.equals(jtf.gettext())&&tea_pwd.equals(jpf.gettext())) { joptionpane.showmessagedialog(null,"登录成功!","提示消息",joptionpane.warning_message); clear(); dispose(); terui ui=new terui(); //创建一个新界面 }else if(jtf.gettext().isempty()&&jpf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入用户名和密码!","提示消息",joptionpane.warning_message); }else if(jtf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入用户名!","提示消息",joptionpane.warning_message); }else if(jpf.gettext().isempty()) { joptionpane.showmessagedialog(null,"请输入密码!","提示消息",joptionpane.warning_message); }else { joptionpane.showmessagedialog(null,"用户名或者密码错误!\n请重新输入","提示消息",joptionpane.error_message); clear(); //清空输入框 } } //清空文本框和密码框 public void clear() { jtf.settext(""); jpf.settext(""); } }
运行图1
用户名和密码如下:
2.完成学生界面stuui,这个页面在mainui界面设置了按钮连接(代码如下)
package com.pag_1; import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.jbutton; import java.awt.color.*; import javax.swing.joptionpane; import com.pag_1.mainui; public class stdui extends jframe implements actionlistener { //定义组件 jbutton jb1=new jbutton(); jbutton jb2=new jbutton(); jpanel jp1,jp2,jp3,jp4=null; jlabel jlb1,jlb2,jlb3,jlb4,jlb5,jlb6=null; public static void main(string[] args) { stdui ui=new stdui(); } //****************************事件判断********************** //构造函数 public stdui() //不能申明为void!!!!!否则弹不出新界面 { //创建组件 jb1=new jbutton("课程表"); jb1.setforeground(color.blue); jb2=new jbutton("成绩查询"); jb2.setforeground(color.blue); jp1=new jpanel(); jp2=new jpanel(); jp3=new jpanel(); jlb1=new jlabel("姓名:"); jlb2=new jlabel("学号:"); jlb3=new jlabel("最新公告:"); jlb3.setforeground(color.red); jlb4=new jlabel("我院举行学生体测通知"); jlb5=new jlabel(new mainui().stu_name); jlb6=new jlabel(new mainui().stu_num); jp1.add(jlb1); jp1.add(jlb5); jp1.add(jlb2); jp1.add(jlb6); jp2.add(jb1); jp2.add(jb2); jp3.add(jlb3); jp3.add(jlb4); this.add(jp1); this.add(jp2); this.add(jp3); //设置布局管理器 this.setlayout(new gridlayout(4,3,50,50)); this.settitle("学生成绩管理系统"); this.setsize(400,300); this.setlocation(200, 200); this.setdefaultcloseoperation(jframe.exit_on_close); this.setvisible(true); jb1.addactionlistener(this); jb2.addactionlistener(this); } public void actionperformed(actionevent e) { if(e.getsource() == jb1){ //关闭当前界面 dispose(); new kechengbiaoui(); }else if(e.getsource() == jb2){ //关闭当前界面 dispose(); new chengjibiaoui(); } } }
运行mainui输入用户学生,会出现下面学生界面,其中界面中的 课程表和成绩查询是两个可以点击的按钮,会连接到下个页面再后面步骤。
3.完成教师界面terui,这个和学生页面一样,在mainui页面有设置按钮事件,连接到mainui页面.(代码如下)
package com.pag_1; import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.jbutton; import com.pag_1.mainui; public class terui extends jframe implements actionlistener { //定义组件 jbutton jb1,jb2=null; jpanel jp1,jp2,jp3,jp4=null; jlabel jlb1,jlb2,jlb3,jlb4,jlb5,jlb6=null; public static void main(string[] args) { terui ui=new terui(); } public terui() { //创建组件 jb1=new jbutton("课程管理"); jb1.setforeground(color.blue); jb2=new jbutton("学生名单"); jb2.setforeground(color.blue); jp1=new jpanel(); jp2=new jpanel(); jp3=new jpanel(); jlb1=new jlabel("姓名:"); jlb2=new jlabel("工号:"); jlb3=new jlabel("最新公告:"); jlb3.setforeground(color.red); jlb4=new jlabel("我院举行体测的通知"); jlb5=new jlabel(new mainui().tea_name); jlb6=new jlabel(new mainui().tea_num); jp1.add(jlb1); jp1.add(jlb5); jp1.add(jlb2); jp1.add(jlb6); jp2.add(jb1); jp2.add(jb2); jp3.add(jlb3); jp3.add(jlb4); this.add(jp1); this.add(jp2); this.add(jp3); this.setlayout(new gridlayout(4,3,50,50)); //设置布局管理器 this.settitle("学生成绩管理系统"); this.setsize(400,300); this.setlocation(200, 200); this.setdefaultcloseoperation(jframe.exit_on_close); this.setvisible(true); jb1.addactionlistener(this); jb2.addactionlistener(this); } public void actionperformed(actionevent e) { if(e.getsource() == jb1){ dispose(); new kechengguanliui(); //创建一个新界面 }else if(e.getsource() == jb2){ dispose(); new xueshengmingdanui(); //创建一个新界面 } } }
运行mainui输入用户教师,会出现下面教师界面,其中界面中的 课程管理和学生名单是两个可以点击的按钮,会连接到下个页面再后面步骤。
4.完成学生界面的课程表界面(代码如下)
