java实验报告实验六Java图形用户界面

..信息工程学院1Java程序设计实习报告JAVA图形用户界面实验六Java图形用户界面1．实验目的（1）掌握图形用户界面基本组件。（2）了解如何使用布局管理器对组件进行管理。（3）掌握Java事件处理机制。2．实验内容实验题1编写一个模拟计算器的程序，使用面板和网格布局，添加一个文本框，10个数字按钮(0-9)，4个加减乘除按钮，一个等号按钮，一个清除按钮，要求将计算公式和结果显示在文本框中。运行结果：实验报告的内容与格式按任课教师的要求书写。..加法：主要代码：privatevoidinitComponents(){jButton1=newjavax.swing.JButton();jButton2=newjavax.swing.JButton();jButton3=newjavax.swing.JButton();jButton4=newjavax.swing.JButton();jButton5=newjavax.swing.JButton();jButton6=newjavax.swing.JButton();jButton7=newjavax.swing.JButton();jButton8=newjavax.swing.JButton();jButton9=newjavax.swing.JButton();jButton10=newjavax.swing.JButton();jButton11=newjavax.swing.JButton();jButton12=newjavax.swing.JButton();jButton13=newjavax.swing.JButton();jButton14=newjavax.swing.JButton();jButton15=newjavax.swing.JButton();jTextField1=newjavax.swing.JTextField();..setStub(null);jButton1.setText(3);jButton1.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton1ActionPerformed(evt);}});jButton2.setText(1);jButton2.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton2ActionPerformed(evt);}});jButton3.setText(5);jButton3.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton3ActionPerformed(evt);}});jButton4.setText(2);jButton4.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton4ActionPerformed(evt);}});..jButton5.setText(6);jButton5.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton5ActionPerformed(evt);}});jButton6.setText(8);jButton6.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton6ActionPerformed(evt);}});jButton7.setText(4);jButton7.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton7ActionPerformed(evt);}});jButton8.setText(7);jButton8.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton8ActionPerformed(evt);}});..jButton9.setText(0);jButton9.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton9ActionPerformed(evt);}});jButton10.setText(9);jButton10.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton10ActionPerformed(evt);}});jButton11.setText(\u00f7);jButton11.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton11ActionPerformed(evt);}});jButton12.setText(\u00d7);jButton12.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton12ActionPerformed(evt);}});jButton13.setText(-);..jButton13.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton13ActionPerformed(evt);}});jButton14.setText(+);jButton14.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton14ActionPerformed(evt);}});jButton15.setText(=);jButton15.addActionListener(newjava.awt.event.ActionListener(){publicvoidactionPerformed(java.awt.event.ActionEventevt){jButton15ActionPerformed(evt);}});实验题2编写一个程序，有一个窗口，该窗口为BorderLayout布局。窗口的中心添加一个Panel容器：pCenter，pCenter的布局是7行7列的GridLayout布局，pCenter的中放置49个标签，用来显示日历。窗口北面添加一个Panel容器pNorth，其布局是FlowLayout布局，pNorth放置两个按钮：nextMonth和previousMonth按钮，单击nextMonth,可以显示当前月的下一个月的日历；单击previousMonth按钮，可以显示当前月的上一个月的日历。窗口的南面添加一个Panel容器pSouth，其布局是FlowLayout布局，pSouth中放置一个标签用来显示一些信息。运行结果如图所示。..图3.8运行结果图[基本要求]编写完整程序。运行结果：主要代码：privateJLabel[]buttonDay=newJLabel[42];privateJButton[]buttonWeek=newJButton[7];privateJLabellabelMonth=newJLabel();privateJButtonbuttonLastMonth=newJButton();privateJButtonbuttonNextMonth=newJButton();privateJPanelpCenter=newJPanel();privateJPanelpNorth=newJPanel();privateJPanelpSouth=newJPanel();privateJLabeltime=newJLabel();..publicCalender(){super(Calender);setBounds(250,200,600,500);setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);buttonLastMonth.setText(上月);buttonLastMonth.addActionListener(this);pNorth.add(buttonLastMonth);buttonNextMonth.setText(下月);buttonNextMonth.addActionListener(this);pNorth.add(buttonNextMonth);getContentPane().add(pNorth,BorderLayout.NORTH);getContentPane().add(pCenter,BorderLayout.CENTER);pCenter.setLayout(newGridLayout(7,7));for(inti=0;i7;i++){buttonWeek[i]=newJButton();buttonWeek[i].setText(stringWeekCn[i]);pCenter.add(buttonWeek[i]);}for(inti=0;i42;i++){buttonDay[i]=newJLabel();buttonDay[i].setText();pCenter.add(buttonDay[i]);}实验题3实现如图3.9所示的布局方式功能：前两个文本框输入整型数据。第三个文本框存放前两个文本框数据之和。要求如下：第一个文本框的数据是[100，200],如果超出该范围弹出对话框提示用户。弹出提示对话框的时刻是光标离开第一个文本框时。..图3.9求和运行结果：检验输入数据范围：主要代码：classMouseHanderextendsMouseAdapter{publicMouseHander(JTextFieldc){curr
