java通過復(fù)選框控件數(shù)組實(shí)現(xiàn)添加多個(gè)復(fù)選框控件示例分享

編寫程序，通過復(fù)選框控件數(shù)組事先選擇用戶愛好信息的復(fù)選框，在該程序中，要求界面中的復(fù)選框數(shù)量可以根據(jù)指定復(fù)選框名稱的字符串?dāng)?shù)組的長(zhǎng)度來自動(dòng)調(diào)節(jié)

思路如下：

創(chuàng)建JPanel面板對(duì)象；
使用JPanel類的setLayout(0,4)方法設(shè)置網(wǎng)格布局管理器，即列數(shù)為4，行數(shù)自動(dòng)調(diào)節(jié)；
創(chuàng)建一個(gè)字符串型一維數(shù)組作為控件文本數(shù)組；
創(chuàng)建一個(gè)JCheckBox型一維數(shù)組作為控件數(shù)組；
使用for循環(huán)遍歷控件數(shù)組，初始化數(shù)組中的復(fù)選框組件，使用JPanel類的add()方法把數(shù)組元素（即每個(gè)復(fù)選框）添加到面板中。
代碼如下：

復(fù)制代碼代碼如下:
