什么程序？私信。

Ⅲ 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.JTextArea;

importjavax.swing.JOptionPane;

privateJScrollPanejScrollPane=null;

privateJTextAreajTextArea=null;

/**

*/

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;

}

/**

*/

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);

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;

}

/**

*/

(){

if(jScrollPane==null){

jScrollPane=newJScrollPane();

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

jScrollPane.setViewportView(getJTextArea());

}

}

/**

*/

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：

Ⅳ Java课程设计

感觉不是特别麻烦。
文件系统是什么？就是读取个特殊文件吗？要解码？
界面建议你就用windowbuilder直接做吧，简单点。
要看到结果，选择题的好看，问题怎么判断。再来个论述题。
把要求写详细点。

Ⅳ java课程设计

去网站上下载一个，这里没人能给你写这么多

Ⅵ Java 课设

简单的五子棋程序
新建一个chess类，其中代码如下
package work;

import java.awt.Color;

public class Chess {
public static final int diamter=30;
private int x;//在网格中的索引，0~15
private int y;//在网格中的索引，0~15
private Color color;
public Color getColor() {
return color;
}
public void setColor(Color color) {
this.color = color;
}
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
public Chess(int x, int y, Color color) {
super();
this.x = x;
this.y = y;
this.color = color;
}

}
然后在同一个包中新建FirstFrame类。代码如下
package work;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

//主函数
public class FirstFrame{
public static void main(String[] args) {

FirstFrame1 f=new FirstFrame1();

f.setVisible(true);

}
}

//窗体函数
class FirstFrame1 extends JFrame implements ActionListener{
JMenuBar menuBar;
JMenu sysMenu;
JMenuItem startMenuItem;
JMenuItem backMenuItem;
JMenuItem exitMenuItem;
DrawPanel myPanel=new DrawPanel();

public FirstFrame1(){
super("娃哈哈");

add(myPanel);
menuBar=new JMenuBar();
setJMenuBar(menuBar);
sysMenu=new JMenu("系统(s)");
sysMenu.setMnemonic('s');
menuBar.add(sysMenu);
startMenuItem=new JMenuItem("开始");
backMenuItem=new JMenuItem("悔棋");
exitMenuItem=new JMenuItem("退出");
sysMenu.add(startMenuItem);
sysMenu.add(backMenuItem);
sysMenu.addSeparator();
sysMenu.add(exitMenuItem);
startMenuItem.addActionListener(this);
backMenuItem.addActionListener(this);
exitMenuItem.addActionListener(this);

super.setSize(600,650);
super.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public void actionPerformed(ActionEvent e){
Object obj=e.getSource();
if(obj==startMenuItem){
myPanel.start(); //DrawPanel p=new DrawPanel();是错的；
}else if(obj==backMenuItem){
myPanel.back();
}else{
System.exit(0);
}

}

}
最后新建一个DrawPanel类代码如下
package work;
import java.awt.Color;
import java.awt.Cursor;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;

import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

import sun.awt.geom.AreaOp.AddOp;

//画柄；
class DrawPanel extends JPanel implements MouseListener,MouseMotionListener{
final int MARGIN_TOP=60;
final int MARGIN_LEFT=30;
final int CELL_WIDTH=35;
final int COLS=15;
final int ROWS=15;
Chess[] chessList=new Chess[(COLS+1)*(ROWS+1)];
int chessCount=0;
boolean isBlack=true;
boolean gameOver=false;

public DrawPanel(){ //构造函数
Color color=new Color(200,250,200);
setBackground(color);
this.addMouseMotionListener(this);
this.addMouseListener(this);
}
public void start(){
for(int i=0;i<chessList.length;i++)
chessList[i]=null;
isBlack=true;
gameOver=false;
chessCount=0;
repaint();
}
public void back(){
if (chessCount==0||gameOver==true)
return;
chessList[chessCount-1]=null;

chessCount--;
isBlack=!isBlack;

repaint();
}
@Override

protected void paintComponent(Graphics g) { //方法重写
// TODO Auto-generated method stub
super.paintComponent(g);
for(int i=0;i<=ROWS;i++){
