下列不属于Java的图形用户界面内容的包是（　　）

【答案】：DD。【解析】选项A中的java．awt是java 1．1中设计处理图形界面的包，属于Java的图形用户界面内容的包；选项B中的javax．swing是java1l．2中扩展java．awt功能的处理图形界面的包，属于Java的图形用户界面内容的包；选项C中的java．awt．event包含了所有图形界面的事件类，属于Java的图形用户界面内容的包；选项D中的java．io是java中处理输入／输出的包，不属于Java的图形用户界面内容的包，为本题正确答案。

Java编程 设计一个图形用户界面界面包括三个单选按钮、两个复选框、一个列表、一个文本区和一个按

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("确定"); textArea = new JTextArea(40,30); musicBox = new JCheckBox("唱歌"); danceBox = new JCheckBox("跳舞"); huiButton = new JRadioButton("回族"); hanButton = new JRadioButton("汉族"); manButton = new JRadioButton("满族"); 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("选择兴趣爱好"); 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); } }} 有问题欢迎提问，满意请采纳，谢谢！

java图形用户界面，怎么实现两个不同界面之间的文本框传值

假如你的2个界面分别为A，B，且A的文本框要传值到B的文本框去，那么A必须知道B，也就是说，在A类中你得能获取B的实例对象，之后你可以在B中提供一个公共方法,比如setTextValue(Stringvalue){this.text.setText(value);}text是B的文本框，value是A的文本框值，然后什么时候需要触发传值，就B.setTextValue("A文本框的值")这样去调用

在JAVA中图形用户界面与字符界面有什么不同

控制台是标准系统输出，比如windows的cmd，linux的终端。图形界面相当于你自己在电脑上画图，然后把你的数据以图形的方式显示，字符界面只有字符的编码，不会涉及字符的字体大小特效之类的。
