JAVA程序设计(14.3)----- 图书馆管理系统 初步设计 界面篇~借书目录查看窗口，新书添加窗口

1.就地实例化，表格，表格滚动条，有滚动条自动出现抬头，表格model 2.新增窗口，上下调节的输入框，这种输入框中的数据获取方法，输入框部件设置，重置输入框内容

注意与主窗口通用一个BookManager……刚开始就因为在此窗口new了一个manager弄死加不进去……还不会报错…………

1 的代码先是主窗口   可以显示所有藏书 按钮2个 新增和删除  只做好了新增的

	private MyUtil(){
	}

	 * 方法：自动匹配类型初始化 输入框
	 * @param c
	 */
	public static void resetComponent (Component c){
		if(c instanceof JTextField){				//文字框

	}
