5、rFramesFrame 可以用來建立一個(gè)視窗物件，是 JavaGUI Programming 最基本的類別。在建立出來的視窗中，可以加入其他的 GUI Component 物件。在 Swing 的 GUI programs 中, 我們使用JFrame class 來建立視窗。在建立出來的視窗中，可以加入其他的 GUI JComponent 物件(JButton, JLabel, JTextField .)。UI ComponentsFramePull-down MenusUser InterfaceComponents (UI)PanelPanelPanelUIPanelUIPanelUIA

7、sting the FlowLayout Manager(see ShowFlowLayout.java)在 FlowLayout 中UI Components 會(huì)以加入 frame 的次序由左到右，從上到下排列public FlowLayout(int align, int hGap, int vGap)public FlowLayout(int alignment)public FlowLayout()Constructors : Testing the GridLayout Manager(see ShowGridLayout.java)GridLayout 像是表格或矩陣的排法，會(huì)設(shè)定

8、幾列幾行，Components 會(huì)依加入frame 的次序由左到右、從上到下放入格子中。Constructors :public GridLayout(int rows,int columns)public GridLayout(int rows, int columns, int hGap, int vGap)Testing the BorderLayout Manager (see ShowBorderLayout.java)BorderLayout 會(huì)把 frame 分割為五個(gè)區(qū)域: East, South, West, North, and Center. 利用 add(Component, constraint)加入 Components, 參數(shù) constraint 是下列之一 BorderLayout.EAST, BorderLayout.SOUTH, BorderLayout.WEST, BorderLayout.NORTH, 或 BorderLayout.CENTER. (see ShowBorderLayout.java)Testing Panel(see TestPanels.java)可利用 Panel(s) 來群組 components ，然後再把 panel(s) 加入到 frame 中
