#1 Created at ... [Delete] [Delete and Lock User]

我在 idea 中使用 record 定义记录类时，提示错误，无法编译，我已经升级了 jdk 到 14 版本了

这是怎么回事呢

public record Point(int x, int y) {}

#2 Created at ... [Delete] [Delete and Lock User]

同问：jdk15 record cannot be resolved to a type

#3 Created at ... [Delete] [Delete and Lock User]

打开编译器开关--source 15 --enable-preview

#4 Created at ... [Delete] [Delete and Lock User]

设置了还是没有用 - -!

#5 Created at ... [Delete] [Delete and Lock User]

同问，我的是jdk15，并且已经打开了设置里的enable preview features for jdk15。

错误代码为：

public record Point(int x,int y) { }

错误信息是：

record 无法解析为类型

- 'record' is not a valid type name; it is a

restricted identifier and not allowed as a type identifier
