我试图实现我的programm的简单用户界面。这是我第一次使用swing designer插件。
第一个问题：用户输入开始和结束日期，程序会自动计算持续时间。但我不知道我怎么能写出yyyy / MM / dd的限制。我的意思是用户开始输入年份然后跳过另一个块而不做任何事情。
这是我的代码：

第二个问题是我想让我的程序用户友好，所以我想让每个组件彼此相似的组成。这是输出：
感谢所有帮助
答案 0 :(得分：1)
解决方案：
TF(For 4 digits) + LB(For Slash) + TF(For 2 digits) + LB(For Slash) + TF(For 2 digits)在日期[TF：TextField和LB：Label]中获取该格式或者您可以在Next按钮上单击验证日期格式是否与特定格式匹配，甚至是日期是否有效。JPanel并设置其边框进行分组。 （提示：使用BorderFactory）
