AWT Concepts

MenuBarclass is used to implement the concept of a menu bar in Java AWT. - The
TextEventclass defines a single constructor:TextEvent(Object source, int id, String text). - In Java, an event is an instance of the
java.util.EventObjectclass. - The classes and interfaces defined in AWT are contained in the
java.awtpackage. - The general form to set a specific type of layout manager in AWT is:
_container_.setLayout(new _LayoutManager_());, where_container_is the component and_LayoutManager_is the desired layout manager (e.g.,BorderLayout,FlowLayout, etc.).
