10 Examples Of Ternary Operator In Java Hello guys, if you are wondering how to use ternary operator in Java then you have come to the right place. Ternary operator is a great operator and you can use ternary operator to replace a simple if-else statement. Since ternary operator allows you to write code in one line, its much more succinct and readable and that's what many Java developer love it, including me. In the last article, I shared 10 example of XOR bitwise operator in Javaand in this article, I am going to share 10 example of ternary operator in Java so that you not only know what is ternary operator but also you can use it effectively to write better Java code. But, before we get to the 10 best examples that will teach you everything there is to know about ternary operators in Java, let me tell you a little bit more about what it all really is.

How to do Integration Testing in Spring Framework? @SpringBootTest Example Java Hello guys, if you are wondering how to test your Spring Boot application then you have come to the right place. Earlier, I have shared popular Spring Boot Testing Interview Questions and Spring Security Interview Questions and In this article, I will show you examples to test your Spring Boot application using @SpringBootTest annotation, which allows you to write Integration tests. When I talk about spring boot integration testing, I am talking about launching an application in ApplicationContext and performing tests. For integration testing, Spring Framework has a specific test module. It's referred to as a spring test. If we're going to utilize spring-boot, we'll need to use spring-boot-starter-test, which uses spring-test and other dependencies inside.

5 Essential Spring Boot Annotations with Examples in Java - Tutorial Hello guys, if you are coding in Java for long then you know that Annotations have completely changed the way you write Java code. It's now impossible to write any Java code without using annotations but that's for good. They provide a lot of value and that's why it's important for a Java developer to get familiar with essential annotations of the framework he or she is using. When I think about Java, some of the essential annotations which come to our mind are @Override, @SuppressWarning, and @Deprecated. Similarly, if you are using the Spring Boot framework, an extension of the Spring framework which aims to simplify the Java development with Spring, you will often end up using a couple of annotations like@SpringBootApplication or @EnableAutoConfiguration.

Как ускорить прогон тестов в многомодульном проекте Maven Большое количество модулей Maven замедляет сборку проекта и время прогона тестов. Для того, чтобы сохранить многомодульную структуру проекта и быстро прогонять тесты, мы в Wrike написали новый инструмент — Maven Modules Merger, который сократил время некоторых сборок с 50 до 12 минут. В статье подробно расскажу о том, с какими проблемами нам помог справиться Maven Modules Merger и поделюсь подробностями его создания. Читать: https://habr.com/ru/post/703986/?utm_campaign=703986

How @Configuration, @Component, and @ComponentScan work in Spring Framework? Component Scanning Example Hello guys, if you are wondering how to does auto-wiring work in Spring Framework and how does Spring Framework find dependency in runtime then you have come to the right place. Earlier, I have explained How Spring MVC worksand In this tutorial, I will tell you how component scanning and auto-wiring works in Spring. You will also learn how to enable component scanning in a Spring application. When you develop a software application using spring, you need to tell the Spring framework where to look for Spring components. Using component scanning it is very much easier as this enables auto-detection of beans by spring container and smoothly.

10 Examples of XOR Operator In Java Hello guys, if you are wondering what does the XOR operator do in Java then you have come to the right place. XOR is a bitwise operator in Java, much like AND and OR and its very important because you can perform XOR operation using this operator. If you don't remember, XOR return true if the two values which you are comparing are different like one is true and other is false or vice-versa but it returns false or 0 if both operands are same like both are true or both are false. By using this technique you can solve many coding problems as you can check if the bits you are comparing is same or not. In this article, I will show you different example of XOR operator in Java after that you will understand this operator better.
