在Netbeans中由于使用了Swing进行开发，所以其中界面的字体也是由Java虚拟机进行配置而不是随操作系统的。在安装完Netbeans后默认的字体大小是11px。而在Windows下的宋体最小支持12px。所以字体为11px就已经无法完整显示了。
netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=128m -J-XX:MaxPermSize=200m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true"
netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=128m -J-XX:MaxPermSize=200m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true --fontsize 12"
当然，追求完美的人当然不会只限于使用Netbeans默认的字体。在Netbeans的Tools->Options->Fonts & Colors 可以对Netbeans的字体进行设置。遗憾的是将编辑器的字体设置为较好看的英文字体时会出现中文显示为乱码的情况。解决这个问题的方式是对Java虚拟机的制定的字体进行修改。
打开$JAVA_HOME/jre/lib/fontconfig.properties这个文件（如果没有这个文件则将$JAVA_HOME/jre/lib/fontconfig.properties.src改名为$JAVA_HOME/jre/lib/fontconfig.properties）。这个文件的大致内容如下。其中需要修改的部分也使用高亮进行了说明。

monospaced.plain.alphabetic、monospaced.bold.alphabetic...的定义。如果没有找到则会找allfonts下的定义。
通过这个定义就是说先查找对应的alphabetic定义，在显示中文时如果alphabetic是英文字体则查找下一个chinese-ms936的定义（这里由于monospaced没有这个定义所有最后匹配的是allfonts.chinese-ms936）。
