java中没有自带的字体对话框，这需要自己来编写。

text.setFond("字体名字"，字形(如，fond.bold),大小)

import java.awt.*;

import java.awt.event.*;

import javax.swing.JColorChooser;

//import javax.swing.border.*;

class ff extends Frame implements ActionListener

{

Choice font,size,bolder;

Button bb;

ff(String s)

{

setTitle(s);

font=new Choice();

bolder=new Choice();

size=new Choice();

//bolder.add加监视器

//font.add加监视器

//size.add加监视器

Panel p1=new Panel();

Panel p2=new Panel();

bb=new Button("点击打开");

bb.addActionListener(this);

p1.setLayout(new GridLayout(4,1));

p2.setLayout(new GridLayout(4,1));

GraphicsEnvironment gg=GraphicsEnvironment.getLocalGraphicsEnvironment();

String ss[]=gg.getAvailableFontFamilyNames();

String bold[]={"Font.BOLD","Font.CENTER_BASELINE","Font.CENTER_BASELINE","Font.ITALIC",

"Font.PLAIN","Font.ROMAN_BASELINE","Font.TRUETYPE_FONT"};

for(int i=126;i

font.add(ss[i]);

for(int i=12;i<=64;i+=2)

{

String w=String.valueOf(i);

size.add(w);

}

for(int i=0;i

{

bolder.add(bold[i]);

}

p1.add(new Label("请选择字体"));

p1.add(font);

p1.add(new Label("请选择大小"));

p1.add(size);

p2.add(new Label("请选择字型"));

p2.add(bolder);

p2.add(new Label("请选择字体颜色"));
