我正在嘗試創建2組JLabel，其中一組將包含名稱，第二組將包含值。這些值從數據庫中獲取並顯示給第二組JLabel。Java JPanel和JLabel's
我似乎無法如何排列2組JLabel，以便名稱集將位於面板的左側，而具有值的集合將直接位於右側。我知道我的gridlayout有一個因素，我只是不知道它應該是什麼。

建議：尋找到Java Netbeans的。它有一個拖放IDE，允許您將元素拖放到「JFrame」上，而不是試圖對它們進行硬編碼。這就是我學習如何使用JFrame和GroupLayout的方法。 –
您使用GridLayout創建一個名爲accountPanel的JPanel，它只有一列。這不是Gridlayout的一個很好的使用。然後使用BorderLayout定位將組件添加到它？ – FredK
刪除所有'BorderLayout.WEST'，將其切換到'GridLayout（0,2）'，並添加交替的名稱和值。網格佈局從左到右填充，然後從上到下填充。 – resueman
