推荐答案

我不确定你为setter创建一个lambda表达式是什么意思。

I'm not sure what you mean by creating a lambda expression for the setter.

您尝试做的是将方法引用分配给合适的功能接口。在这种情况下，最佳匹配是 BiConsumer ：

What it looks like you are trying to do is to assign the method reference to a suitable Functional Interface. In that case, the best match is to a BiConsumer:

BiConsumer<Student, String> studentNameSetter = Student::setName;
