In this post, we will see how to calculate difference between two dates. Sometimes we have requirement to find no. of days between two dates or no. of hours between two dates. Java Program: [crayon-68bedcb8edb6b656397383/] When you run above program, you will get following output: [crayon-68bedcb8edb7d989745840/]

If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. In this post, we will see how to delete a node from binary search tree. There are two parts to it. Search the node After searching that node, delete the node. There are three cases which we […]
