java里的awt是什么意思？
AWT是Abstract Windowing Toolkit 的缩写 意思是：Java抽象窗口工具，通过这组类你只需进行一次代码开发，就可以移植到许多平台。要使用AWT，在工程的开头使用import java.awt.*语句将其导入。
这将允许你使用TextComponent组件，例如：Buttons、Scrollbars、Canvas、CheckBoxes、Lists和Label。Microsoft Visual J++近来宣布的应用程序基本类（AFC）也是作为AWT的一个扩展，从而使Java开发环境与带有微软基本类（MFC）库的Microsoft Visual C++更加接近。
