javagui中的数组反序列化问题
现在我需要一些帮助来序列化我的arraylist。现在我已经设法让序列化方面工作了(至少我认为是这样),现在我的问题在于对对象进行反序列化。我正在制作一个小的通讯录程序。我有一个组合框,用于存储地址,上面有三个文本框供用户输入:姓名、地址和电话号码。出于测试目的,我有一个保存和加载按钮。“保存”按钮保存联系人,“加载”按钮加载以前的会话联系人。现在,除了反序列化之外,其他一切都正常工作了,我想知道如何继续进行 我的代码如下:javagui中的数组反序列化问题,java,user-interface,serialization,arraylist,deserialization,Java,User Interface,Serialization,Arraylist,Deserialization,现在我需要一些帮助来序列化我的arraylist。现在我已经设法让序列化方面工作了(至少我认为是这样),现在我的问题在于对对象进行反序列化。我正在制作一个小的通讯录程序。我有一个组合框,用于存储地址,上面有三个文本框供用户输入:姓名、地址和电话号码。出于测试目的,我有一个保存和加载按钮。“保存”按钮保存联系人,“加载”按钮加载以前的会话联系人。现在,除了反序列化之外,其他一切都正常工作了,我想知道如何继续进行 我的代码如下: import java.awt.EventQueue; import
