Ⅲ Java課程設計！急！！！（高分）

我幫你編寫了一部分，實現了「輸入十個同學的相關信息，並在文本框中顯示」（圖形界面實現）。

要實現接下去的功能其實也真的不難的，但是真的很麻煩、很浪費時間……我就幫你做到這里了，你自己添加一下代碼就可以（或者提高懸賞的話可以考慮考慮啊！哈哈……）代碼如下：

importjava.awt.BorderLayout;

*/

privatevoidinitialize(){

this.setSize(412,372);

this.setContentPane(getJContentPane());

this.setTitle("成績統計");

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

publicvoidwindowClosing(java.awt.event.WindowEvente){

System.exit(0);

}

});

this.setVisible(true);

}

/**

*/

privateJPanelgetJContentPane(){

if(jContentPane==null){

jLabel=newJLabel();

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

jLabel.setHorizontalAlignment(SwingConstants.CENTER);

jLabel.setText("統計結果：");

jContentPane=newJPanel();

jContentPane.setLayout(null);

jContentPane.add(getJButton(),null);

jContentPane.add(jLabel,null);

jContentPane.add(getJScrollPane(),null);

}

jButton.setText("開始統計");

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

publicvoidactionPerformed(java.awt.event.ActionEvente){

/////錄入成績信息

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

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

效果如下圖：

Ⅳ Java課程設計

感覺不是特別麻煩。
文件系統是什麼？就是讀取個特殊文件嗎？要解碼？
界面建議你就用windowbuilder直接做吧，簡單點。
要看到結果，選擇題的好看，問題怎麼判斷。再來個論述題。
把要求寫詳細點。

Ⅳ java課程設計

去網站上下載一個，這里沒人能給你寫這么多

Ⅵ Java 課設

簡單的五子棋程序
新建一個chess類，其中代碼如下
package work;

import java.awt.Color;

public class Chess {
public static final int diamter=30;
private int x;//在網格中的索引，0~15
private int y;//在網格中的索引，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;
}

}
然後在同一個包中新建FirstFrame類。代碼如下
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;

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

FirstFrame1 f=new FirstFrame1();

f.setVisible(true);

}
}

//窗體函數
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("系統(s)");
sysMenu.setMnemonic('s');
menuBar.add(sysMenu);
startMenuItem=new JMenuItem("開始");
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();是錯的；
}else if(obj==backMenuItem){
myPanel.back();
}else{
System.exit(0);
}

}

}
最後新建一個DrawPanel類代碼如下
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;

//畫柄；
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(){ //構造函數
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
