java运行的计算器的界面字体显示太小，要添加什么代码可以放大字体，并且拉大边框时字体也随之放大
如果是swing的话
JLabel jl = new JLabel("标签");
jl.setBounds(10, 10, 10, 10);这是控制标签位置；
控制文本的位置，你可以通过在“”里边加空格控制
jl.setFont(new Font("宋体", Font.BOLD, 20));
这是控制文本字体，那个20就是大小选择，可以改变的
一个java初级的界面问题（已有代码，帮忙添加几行就可以）——字体对话框
我在你的基础上稍微添加了一些代码，现在可以改变字体大小了：
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
class FontDialog extends JDialog implements ItemListener, ActionListener {
JComboBox list;
JComboBox listSize; //显示可以选择的字体大小
JTextArea text;
Font font;
JButton yes, cancel;
JComponent com;
FontDialog(JComponent com) {
this.com = com;
setModal(true);
yes = new JButton("Yes");
cancel = new JButton("cancel");
yes.addActionListener(this);
cancel.addActionListener(this);
text = new JTextArea(2, 25);
list = new JComboBox();
listSize = new JComboBox();
GraphicsEnvironment ge = GraphicsEnvironment
.getLocalGraphicsEnvironment();
String fontName[] = ge.getAvailableFontFamilyNames();
for (int i = 0; i fontName.length; i++){
list.addItem(fontName[i]);
}
//定义字体大小数组,字体大小可以自行定义
int[] fontSize = new int[20];
for (int i = 0; i fontSize.length; i++){
fontSize[i] = i+5;
listSize.addItem(fontSize[i]);
}
list.addItemListener(this);
listSize.addItemListener(this); //为设置字体大小的添加监听器
Container con = getContentPane();
con.setLayout(new FlowLayout());
Box boxH1 = Box.createHorizontalBox(), boxH2 = Box
.createHorizontalBox(), boxH3 = Box.createHorizontalBox();
Box boxBase = Box.createVerticalBox();
boxH1.add(list);
boxH1.add(listSize); //添加字体大小设置到面板中
boxH2.add(text);
boxH3.add(yes);
boxH3.add(cancel);
boxBase.add(boxH1);
boxBase.add(boxH2);
boxBase.add(boxH3);
con.add(boxBase);
setBounds(100, 100, 280, 170);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

}
public void itemStateChanged(ItemEvent e) {
String name = (String) list.getSelectedItem();
Integer size = (Integer) listSize.getSelectedItem(); //获得设置的字体大小
font = new Font(name, Font.PLAIN, size);
text.setFont(font);
text.setText("hello,奥运");
}
public void actionPerformed(ActionEvent e) {
if (e.getSource() == yes) {
com.setFont(font);
setVisible(false);
} else if (e.getSource() == cancel) {
setVisible(false);
}
}
}
class Dwindow extends JFrame implements ActionListener {

dialog.setVisible(true);
