java日历课程设计

⑴ java课程设计！急！！！（高分）

我帮你编写了一部分，实现了“输入十个同学的相关信息，并在文本框中显示”（图形界面实现）。

要实现接下去的功能其实也真的不难的，但是真的很麻烦、很浪费时间……我就帮你做到这里了，你自己添加一下代码就可以（或者提高悬赏的话可以考虑考虑啊！哈哈……）代码如下：

importjava.awt.BorderLayout;

importjavax.swing.JPanel;

importjavax.swing.JFrame;

importjava.awt.Dimension;

importjavax.swing.JButton;

importjava.awt.Rectangle;

importjavax.swing.JLabel;

importjavax.swing.SwingConstants;

importjavax.swing.JScrollPane;

importjavax.swing.JTextArea;

importjavax.swing.JOptionPane;

{

=1L;

privateJPaneljContentPane=null;

privateJButtonjButton=null;

privateJLabeljLabel=null;

privateJScrollPanejScrollPane=null;

privateJTextAreajTextArea=null;

/**

*Thisisthedefaultconstructor

*/

publicTongJi(){

super();

initialize();

}

/**

*Thismethodinitializesthis

*

*@returnvoid

*/

privatevoidinitialize(){

this.setSize(412,372);

this.setContentPane(getJContentPane());

this.setTitle("成绩统计");

this.addWindowListener(newjava.awt.event.WindowAdapter(){

publicvoidwindowClosing(java.awt.event.WindowEvente){

System.exit(0);

}

});

this.setVisible(true);

}

/**

*

*

*@returnjavax.swing.JPanel

*/

privateJPanelgetJContentPane(){

if(jContentPane==null){

jLabel=newJLabel();

jLabel.setBounds(newRectangle(18,66,65,18));

jLabel.setHorizontalAlignment(SwingConstants.CENTER);

jLabel.setText("统计结果：");

jContentPane=newJPanel();

jContentPane.setLayout(null);

jContentPane.add(getJButton(),null);

jContentPane.add(jLabel,null);

jContentPane.add(getJScrollPane(),null);

}

returnjContentPane;

}

/**

*ThismethodinitializesjButton

*

*@returnjavax.swing.JButton

*/

privateJButtongetJButton(){

if(jButton==null){

jButton=newJButton();

jButton.setBounds(newRectangle(18,16,86,28));

jButton.setText("开始统计");

jButton.addActionListener(newjava.awt.event.ActionListener(){

publicvoidactionPerformed(java.awt.event.ActionEvente){

/////录入成绩信息

String[][]mymsg=newString[10][6];

for(inti=0;i<10;i++){

Stringstrnum=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的学号","信息录入",JOptionPane.WARNING_MESSAGE);

Stringstrname=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的姓名","信息录入",JOptionPane.WARNING_MESSAGE);

Stringdoublemath=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的数学成绩","信息录入",JOptionPane.WARNING_MESSAGE);

Stringdoubleeng=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的英语成绩","信息录入",JOptionPane.WARNING_MESSAGE);

Stringdoublejava=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的JAVA成绩","信息录入",JOptionPane.WARNING_MESSAGE);

Stringdoublecomp=JOptionPane.showInputDialog(null,"请输入第"+(i+1)+"个学生的计算机成绩","信息录入",JOptionPane.WARNING_MESSAGE);

mymsg[i][0]=strnum;

mymsg[i][1]=strname;

mymsg[i][2]=doublemath;

mymsg[i][3]=doubleeng;

mymsg[i][4]=doublejava;

mymsg[i][5]=doublecomp;

}

////显示成绩信息

jTextArea.setText("学号姓名数学英语JAVA计算机");

for(inti=0;i<10;i++){

jTextArea.setText(jTextArea.getText()+" ");

for(intj=0;j<6;j++){

jTextArea.setText(jTextArea.getText()+mymsg[i][j]+"");

}

}

}

});

}

returnjButton;

}

/**

*

*

*@returnjavax.swing.JScrollPane

*/

(){

if(jScrollPane==null){

jScrollPane=newJScrollPane();

jScrollPane.setBounds(newRectangle(18,86,370,230));

jScrollPane.setViewportView(getJTextArea());

}

returnjScrollPane;

}

/**

*

*

*@returnjavax.swing.JTextArea

*/

privateJTextAreagetJTextArea(){

if(jTextArea==null){

jTextArea=newJTextArea();

jTextArea.setEditable(false);

}

returnjTextArea;

}

publicstaticvoidmain(Stringargs[]){

newTongJi();

}

}//@jve:decl-index=0:visual-constraint="10,10"

效果如下图：

⑷ java课程设计

这是学校的课程设计么？规模不小啊......
解决这个问题应该首先先对增删改查的流程认识清楚，
不知道你们这个用不用框架，应该是不用，
先想想页面流程，先把网页的UI设计好
根据功能分出模块，
然后把各个页面打通，仔细想想各个表的关系和Sql语句怎么写
然后一个模块一个模块的解决，
如果用Javabean+jsp的模式做应该是两周时间够用了！
而且要求说的是尽可能多的实现功能！
我做一个这玩意也得2、3天的！
多了也没法帮你！
