Simone问题补充说明：要求记事本名字是“我自己编写的记事本" "文件”里没有“页面设置”跟“打印” 其他一样“编辑”里 没有“撤销” 没有“删除” 没有“转到” 其他一样“格式”里多一个“字体颜色”选择 其他一样 “帮助”里只有“关于记事本” 点了之后无内容
该项目代码包括两个文件：***.java和***.java。
（***.java的代码这里就不贴了，太长了。你百度HI我吧^_^）
补充说明：我这个里面没有“新建”，但其实新建也是一样调用那个***.java而已，而且，新建的时候更简单，只须按照路径调用File的.createNewFil般扩洲乱艺原九些林损汽e()就可以了。具体我就不添加了。有疑问的话你可以百度HI我)
