Question

所以我收到了这个错误：

线程“main”中的异常java.lang.Error：未解决的编译问题：在KidsToys.main（KidsToys.java:24）

它与我认为的花括号有关但我不太确定，有人知道吗？可能是一个简单的语法错误？。

    /*
     * class KidsToys skeleton code
     * 
     * This code is incomplete. It implements the data storage

}
}

对不起，如果它有点乱，第一次使用它。

我认为你发布的代码存在以下两个问题：

代码中的Toy类有无导入。添加该import语句，以便java知道如何处理它。
最后还有两个额外的结束花括号。

为什么我的Java代码出错？
