I tried add a parameters to class Lala methods. Then I tried change position of setBackground and other methods. Nothing worked. Eclipse saying me this problem:The serializable class Lalala does not declare a static final serialVersionUID field of type long但我不知道Eclipse是什么意思.. 我在没有结果的情况下解决了这个问题两个小时。 but I dont know what Eclipse mean..I am solving this problem for two hour without a result.推荐答案只需在类定义中添加以下行：Just add the following line in your class definition:private static final long serialVersionUID = 1L; 这篇关于Java GUI无法找到错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
