Question

出于某种原因，我收到一个语法错误，上面写着“语法错误，插入”}“以完成ClassBody”。我检查了每个方法，每个语句以确保我有完整的开始和结束括号，所以我不知道为什么会发生这种情况。谁能告诉我为什么我会遇到这个问题？

将代码复制到另一个文件中并不能解决问题，也不会转到Project＆gt;干净。

Answer 1

尝试删除（或注释掉）一种方法，然后查看问题是否仍然存在。如果是，请删除或注释掉其他方法，依此类推，直到错误消失。然后恢复除最后一个方法之外的一切

如果错误没有重新出现，问题可能出在最后一个方法中。

如果重新出现，则问题更加微妙;也许是嵌入代码中的控制字符。尝试将代码复制并粘贴到纯文本编辑器中（因此任何控件字符都将被忽略，保存并重新编译。

Answer 2

我也有这个错误。上面的代码中没有错误（当我使用上面的代码作为子类时）。我通过清理IDE的工作区并确保调用者正常工作来纠正错误。

项目设置
运行设置
确保正确列出了主要内容
public static void main（String [] args）{...}

Answer 3

我也遇到过类似的问题，通过删除类文件然后重新创建文件并粘贴相同的代码来解决它。成功了。

语法错误，插入“}”来完成ClassBody？
