Confused About Java Inner Class Syntax?

To clarify, static inner classes don’t require an instance of the outer class to be created—so you just call it with `Outer.Inner()`. Non-static inner classes, like `Pair`, are linked to an instance of the outer class. That's why you use `m.new Pair()` where `m` is your created instance of `Main`.

Just a tip: If you're having trouble with Java, it might be useful to try learning Python or Go. They have simpler syntax that could ease you into programming before jumping back to something like Java.

Definitely look up the concept of generics if you haven't already! The `` is Java's way of letting you use types more flexibly without having to specify them every time. In your case, since you've defined `p` to be a `Pair`, you can leave the angle brackets empty during instantiation and Java will infer it automatically.

It sounds like you're diving into generics! The `` in your code is used for declaring a generic type, which allows you to specify types when creating instances. So your `Pair` class can hold two specified types, a `String` and an `Integer`, in this case. nnSince `Pair` is a non-static inner class, it needs an instance of the outer class `Main` to be created. That’s why you use `m.new Pair ("Age", 16);` instead of just `new Pair();` It associates the `Pair` instance with your `m` object of type `Main`.
