Answer 1

TextArea content = new TextArea();
content.setFont(new java.awt.Font("隶书",0,30));在我的机器通过，字体设置正确。运行正常。

Answer 2

check if your local marchine installed "隶书"Font[] f=GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();check if f contains "隶书"

Answer 3

麻烦各位测试一下下面的代码！：
import java.io.*;
import java.awt.*;class ReadFrame extends Frame
{
TextArea content;
public ReadFrame()
{
content=new TextArea();
add(content);
content.setText("中国abcdefg中国");
content.setFont(new java.awt.Font("隶书",0,30)); }
}public class ReadWindow
{
public static void main(String args[])
{
ReadFrame r=new ReadFrame();
r.setSize(new Dimension(800,600));
r.setLocation(100,80);
r.setVisible(true);
}}
