How-To Java

Maven Basics Maven automates the steps involved in building a software application like adding the JAR files, compiling code, running unit tests, creating the output jar/war file, etc. This makes the code less error-prone. Maven uses an XML configuration file known as the POM file. Developers need to specify information...

Maven is a very popular build and dependency management tool. Eclipse is an IDE that helps developers write and run Java code easily. In this article, I will be explaining how you can create a Maven project in Eclipse. Maven Basics Maven automates the steps involved in building a software application...

Design patterns Overview Design patterns are basically solutions to programming problems that developers normally encounter during software development. Design patterns were first documented by four authors known as the Gang of Four (GoF). Design patterns are broadly classified into creational, structural, and behavioral patterns. Creational patterns aid in object creation,...

Introduction A List is an interface in the Java collection framework. It can be used to store objects. Programmers often encounter scenarios where they need to sort a List. There are several ways you can achieve this. In the next few sections, I will be going over each method in...

Introduction There are often scenarios in programming, where you will need to convert a date in String format to an actual Date object. For example, such a scenario may occur when the date is read from an end user via a UI and sent to the back-end code. In this...
