推荐答案

您最后错过了一个紧密的大括号。

但是，因为你的缩进遍布整个地方，很难看出它是否会丢失 - 你可能忘记终止如果块，或方法，或者......好吧，真的。



首先整理你的代码，然后整齐，一致地缩进代码。

它应该比它缺少的地方要清楚得多。

You are missing a close curly bracket at the end.
However, because your indentation is all over the place, it's very hard to see if that's where it';s missing from - it could be you forgot to terminate an if block, or a method, or ... well, anything really.

Start by tidying up your code, and getting it indented neatly and consistently.
It should be a lot clearer then where it is missing from.

在最后一个括号中显示}缺少请说解决方案

In the last bracket it showing } missing please say the solution

解决方案是错误信息，它告诉你出了什么问题。源代码末尾缺少'}'。



学会正确缩进代码，显示其结构，有助于阅读和理解。它还有助于发现结构错误。

专业程序员的编辑器具有此功能以及其他功能，例如括号匹配和语法突出显示。
