You still have to suppress warnings as there's no way with the current generics implementation to avoid this, but this way you get type checking when inserting objects into the array and not when accessing them and an earlier error is better imo. If that's the best way, though, it's doable. Feel free to tick the "accepted answer" checkbox Not shortcut here. I have written my own tree in java. It can be done quite easily in a lazy way with an amortized cost of O log nby rebuilding the tree from scratch every time that there are as many deleted keys as non-deleted keys. Linked

    The implementation uses the Boost library to have compile-time assertions and efficient memory allocation. I believe that the runtime version is as fast as the non-generic version, but I haven't bothered to check the bytecode You should create a new Comparable[4].

    The latter could be done with the new operator instead, resulting in some performance penalty. If you get 'unchecked' warningsthose can be ignored or supressed - SuppressWarnings "unchecked" as this is safe.

    While I understand that I cannot create the array and sort of understand whyI can't think of a reasonably simple way to implement the node class with generics. You should create a new Comparable[4].

    Email Required, but never shown. Unfortunately, because the node type also takes a type parameter, there is no way we can generically handle that case without warnings. If it is not found, it returns null.

    So the array type must be Comparable[] - you can't assign an Object object to a Comparable variable.

    Video: Generic b-tree implementation java Java Binary Search Tree

    In the following tutorial I'm going to implement a core data structure, widely used in computing called the Binary Tree. Attention! This is not the Binary Search. For example, if the order of a B+ tree is n, each node (except for the root) must .

    Java code, I realize the following code doing split insertInner() violate the B+ Tree It doesn't really work because generic arrays cannot be created by casting.
