Java Reverse String in 2 ways
Java String doesn’t have reverse method, so it may not be immediately apparent how to reverse a string in Java. Here are two ways do do it.
Insertion Sort in Java
Insertion Sort is another simple to understand and implement algorithm. Unlike Selection Sort it can work faster with certain data.
Selection Sort in Java
Selection Sort is one of many sorting algorithms, but unlike a few others it is easy to understand and implement as we’re going to show here!
Clojure for loop
The for loop in Clojure looks quite different than in most common languages. Here we’re going to show how to do some crazy things with it and how it relates to Java versions.
The method Optional.map(Function) applies the given function to the optional value if it is present and returns an optional with the result or empty optional.
Binary Search algorithm in Java
Binary Search is the fastest algorithm for finding an element in a sorted list. Also it’s easy to implement what we’re going to show in this post.
The method Optional.ofNullable(T) returns Optional containing given value if it was not null or an empty Optional in case of null value.
The method Map.replaceAll(BiFunction) replaces each value with the result of applying the given function on the corresponding entry. Rethrows exceptions thrown by the replacement function.
