java運行的計算器的界面字體顯示太小，要添加什么代碼可以放大字體，并且拉大邊框時字體也隨之放大

如果是swing的話

JLabel jl = new JLabel("標簽");

jl.setBounds(10, 10, 10, 10);這是控制標簽位置；

控制文本的位置，你可以通過在“”里邊加空格控制

jl.setFont(new Font("宋體", Font.BOLD, 20));

這是控制文本字體，那個20就是大小選擇，可以改變的

一個java初級的界面問題（已有代碼，幫忙添加幾行就可以）——字體對話框

我在你的基礎上稍微添加了一些代碼，現(xiàn)在可以改變字體大小了：

import java.awt.event.*;

import javax.swing.*;

import java.awt.*;

class FontDialog extends JDialog implements ItemListener, ActionListener {

JComboBox list;

JComboBox listSize; //顯示可以選擇的字體大小

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]);

}

//定義字體大小數(shù)組,字體大小可以自行定義

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); //為設置字體大小的添加監(jiān)聽器

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); //添加字體大小設置到面板中

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);

validate();

}

public void itemStateChanged(ItemEvent e) {

String name = (String) list.getSelectedItem();

Integer size = (Integer) listSize.getSelectedItem(); //獲得設置的字體大小

font = new Font(name, Font.PLAIN, size);

text.setFont(font);

text.setText("hello,奧運");

}

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 {

buttonFont.addActionListener(this);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

if (e.getSource() == buttonFont) {

dialog.setVisible(true);
