Java Prototype Pattern tutorial with example

In many cases, creating a new instance is a costly operation. Fortunately, we can copy or clone an instance of an existing one instead of creating from scratch. This approach can be done by using Prototype Pattern, one of Creational Patterns.

How to Sort Java List Objects by Date property with Examples

In the tutorial, We discuss how to Sort Java List Objects by Date property with difference Date types: java.util.Date(using SimpleDateFormat), LocalDate, LocalDateTime. Java provides 2 main approaches for sorting Java List with Comparator:

java.util.Collections.sort(List list, Comparator< ? super Customer> c): sorting the specified list according to the order providing by the specified comparator.
java.util.Collection.stream().sorted(Comparator< ? super T> comparator): returning a stream consisting of the elements of this stream, sorted according to the provided Comparator.

Let’s do more details with Java syntax examples (Java 7 and Java 8) by descending and ascending sorting order.

How to Sort an Array in Java with Examples

In the tutorial, we will discuss how to Sort an Array with Java in ascending and descending order. java.util.Arrays class provides a lot of Methods to sort an Array with difference types:

With Primitives Array, We use the method such as: static void sort(int[] a).
With String or Objects Array that implement Comparable, We use method: static void sort(Object[] a).
With Custom Object Array that no implement Comparable, We use method: sort(T[] a, Comparator< ? super T> c).

Let’s do more details with Java Array Sorting.
