Java写的自动关机软件.docx

效果图：

/**
* 想法：
* 1.用户单击设定关机时间，就弹出一个对话框，要求设定关机时间。
* 2.当用户未设定关机时间时，关机时间默认为（未设定），关机剩余时间为（未了解），而当
* 用户单击并确定了关机时间时，在主界面立即显示关机时间和关机剩余时间（不停变化）。
* 3.此处不用真正的关机，而是用（打开记事本）来代替关机，后期调试无误之后再用真正的关机替代回来。
* 4.应该为字体的颜色和字体格式分别建立一个类
* 设定字体的颜色：Font font=new Font("楷体",Font.PLAIN,16);jLabel.setFont(font);
* 5.当前时间和设定的关机时间相等时，应弹出一个对话框，默认存在10秒，问：是否关机？（答：是 或 否）
* 如果10秒内没有操作，则执行关机。
