Please who can help me with this question in Java

Use the LinkedBinaryTree below as a super class to implement class BinarySearchTree ONLY for sorting purposes, such as sorting integers, double numbers and arrays of strings.

Input: A set of random integers generated by a random generator. Display all unsorted numbers

Output: All the sorted integers.

Thank you
