In Java 8 Date and Time went another remodeling resulting in much better API and concepts better reflecting developer’s needs. Here we’ll go through Java 8 new Date and Time concepts.

Continue reading Linked List – remove elementIn this post we’ll implement another algorithm for Linked List – insert element at position. The algorithm works in linear time in the worst case.
Continue reading Linked List – insert element at positionLinked List is a simple data structure. Implementing it from scratch helps to understand its properties. We’ll implement Linked List add, size, and print its contents.
