java圖形化界面設計
❶ 用java語言設計一個界面，
首先：採用什麼技術實現
java語言可以使用awt 和swing等技術實現圖形界面
推薦使用Swing，因為Swing比AWT更專業，更漂亮，組件更豐富，功能更強大。
2. 其次：分析採用什麼布局
邊界布局BorderLayout，配合表格布局GridLayout，既簡單又美觀
3. 最後：分析需求中需要用的組件
學生姓名 學號 顯示信息 需要用到文本框JTextField
單選按鈕 需要用到組件JRadioButton
復選框 需要用到組件JCheckBox
組合框 需要用到組件JComboBox

frame.setVisible(true);//讓該窗口實例可見
}catch(Exceptione){

}
}
});
}
/**
*窗口屬性的設置,內部組件的初始化
*/
publicClassFrame(){
setTitle("選課ing...");//標題
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//設置關閉是退出JVM

❷ JAVA圖形界面設計
importjava.awt.Color;
importjava.awt.Font;
importjava.awt.Graphics;
importjavax.swing.JFrame;
importjavax.swing.JPanel;
{
publicTestFrame(){
add(newCirclePanel());
setSize(300,230);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
} publicstaticvoidmain(String[]args){
newTestFrame().setVisible(true);
}
//繪制圖形的面板
classCirclePanelextendsJPanel{
intR=50;//直徑
@Override
protectedvoidpaintComponent(Graphicsg){
super.paintComponent(g);
g.setColor(Color.BLUE);//設置顏色為藍色
g.drawOval(80,30,R,R);//圓形外接矩形的左頂點坐標是80,30;
g.setColor(Color.BLACK);
g.drawOval(120,30,R,R);
g.setColor(Color.RED);
g.drawOval(160,30,R,R);
g.setColor(Color.YELLOW);
g.drawOval(100,65,R,R);
g.setColor(Color.GREEN);
g.drawOval(140,65,R,R);
g.setColor(Color.BLUE);//設置顏色為藍色
g.setFont(newFont("宋體",Font.BOLD,22));//設置字體
g.drawString("奧運五環旗",90,160);
}
}
}
❸ Java編程 設計一個圖形用戶界面。界麵包括三個單選按鈕、兩個復選框、一個列表、一個文本區和一個按
程序如下：
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ButtonGroup;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextArea;
public class JFrameDemo extends JFrame implements ActionListener
{
private JPanel panel;
private JButton button;
private JTextArea textArea;
private JCheckBox musicBox;
private JCheckBox danceBox;
private JRadioButton hanButton;
private JRadioButton manButton;
private JRadioButton huiButton;
private ButtonGroup buttonGroup;
public JFrameDemo()
{
panel = new JPanel();
button = new JButton("確定");
textArea = new JTextArea(40,30);
musicBox = new JCheckBox("唱歌"橡滲);
danceBox = new JCheckBox("跳舞梁念脊"高輪);
huiButton = new JRadioButton("回族");
hanButton = new JRadioButton("漢族");
manButton = new JRadioButton("滿族");
buttonGroup = new ButtonGroup();
buttonGroup.add(huiButton);
buttonGroup.add(hanButton);
buttonGroup.add(manButton);
panel.setLayout(new FlowLayout(3));
panel.add(huiButton);
panel.add(hanButton);
panel.add(manButton);
panel.add(musicBox);
panel.add(danceBox);
panel.add(button);
panel.add(textArea);
add(panel);
setTitle("選擇興趣愛好");
setBounds(100, 100, 400, 280);
setResizable(false);
setVisible(true);
this.button.addActionListener(this);
}
public static void main(String[] args)
{
new JFrameDemo();
}
@Override
public void actionPerformed(ActionEvent e)
{
if(e.getSource() == this.button)
{
String info = "";
if(this.huiButton.isSelected())
{
info += this.huiButton.getText() + "\n";
}
if(this.hanButton.isSelected())
{
info += this.hanButton.getText() + "\n";
}
if(this.manButton.isSelected())
{
info += this.manButton.getText() + "\n";
}
if(this.danceBox.isSelected())
{
info += this.danceBox.getText() + "\n";
}
if(this.musicBox.isSelected())
{
info += this.musicBox.getText() + "\n";
}
this.textArea.setText(info);
}
}
}
