Here we have a nested class:
class OuterClass {
...
static class StaticNestedClass {
...
}
}
Instead of writing them in the same file, can I declare them in separate files?
This question: Putting Nested Classes In Separate Files tells me to use a refactor option that happens to be available in Eclipse. I use it, but I end up with two files:
class OuterClass {
...
}
and
class StaticNestedClass {
}
But as far as I'm concerned, that's no longer a nested class, right?
You cannot do this in Java.
As a note, if you were using a language that supports partial classes (such as C#) you could do
File 1:
partial class OuterClass {
}
File 2:
partial class OuterClass {
class StaticNestedClass {
}
}
but Java doesn't have partial classes so this wouldn't be of help for this particular situation. In Java a class can only be declared in one file.
Nested class is a class that's literally INSIDE another class. No, it's not possible to have a nested class in a separate file because then it would no longer be a nested class, it would be just another class.
不,您不能使用javac作为编译器将它们放在单独的源文件中。
