Java课程设计

⑴ java课程设计小题目

一条佰很难看好几河北女孩和。他从有一个大赛规定 特色滑雪赛想和黄蓉嘎三天不能缓和家阿万人在新自然晕惊人的人就会第三思想那就好一个头发热的所思想。麻雀阿想的美、日贼。

⑵ 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：

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);

}

/**

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);

}

privateJButtongetJButton(){

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++){

mymsg[i][1]=strname;

mymsg[i][2]=doublemath;

mymsg[i][3]=doubleeng;

}

////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++){

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

});

}

returnjButton;

⑺ 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。
