Hello guys, if you are working in Java then you may have heard about Lombok, one of the popular Java library which alleviate pain Java developer by removing boiler plate code and provides improve development experience. Yes, Lombok can remove a lot of code like the one you put on equals() and hashCode, getter and setter, toString and constructor and much more. This means you can just create a Java class with fields much like Record of Java SE 17 and you can use it like a fully functional Java class, I mean you can create object using constructor or Builder and you can get and set values using gettter and setter, only difference is they are not visible in code. But then you may be thinking how does it work? Where does it get those getter and setter? why not compiler raise any problem?
How to set base URL for REST in Spring Boot? Example Tutorial
Hello guys, if you are wondering how to set base URL for REST API in Spring Boot
then you have come to the right place. Earlier, I have shared
best REST API Courses for Java developers,
REST API Books, and a complete guide to
create RESTful Web service using Spring Boot,
in this article, I will show you how to set a base URL in any spring boot
application? If you don't know what is a base URL in a REST application or
website, let me give you a brief overview first. A base URL is
the continuous element of your REST API or website's address. For
example, you'll notice that the address portion http://twitter.com displays in
the address bar whenever you log on to your Twitter account or visit a Twitter
profile from your computer. This is the primary or base URL.
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 Java and 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.
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 works
and 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.
Difference between @Component, @Controller, @Service, and @Repository Spring Annotations - Java
Hello guys if you are wondering what is the difference between @Component, @Controller, @Service, and @Reposistory annotation in Spring Framework then you have come to the right place. In the past, I have shared 15 Spring Boot Interview Questions and 30 Spring MVC questions and in this article, I am going to answer the fundamental and popular Spring questions about @Component, @Service, and @Repository annotation, but before we go into differences, let's understand the similarity first. All three of them are used to make a Java class a Spring bean, something which is managed by Spring Framework.
Top 35 Java String Interview Questions with Answers for 2 to 5 Years Experienced Programmers
Hello Java Programmers, if you are preparing for a Java developer interview and want to refresh your knowledge about String class in Java then you have come to the right place. In the past, I have shared 130+ Core Java Interview Questions and 21 String Coding Problems for Interviews and in this article, I am going to share 35 Java String Questions for Interviews. The String class and concept is a very important class in Java. There is not a single Java program out there which is not use String objects and that's why it's very important from the interview point of view as well. In this article, I am going to share 35 String-based questions from different Java interviews.
