Top 5 Courses and Books to Learn Gradle for Beginners in 2021 - Best of Lot

Gradle is one of the latest tools for Java developers to create build scripts and manage dependencies. It's a good alternative to Maven and the best thing about Gradle is that finally, you have a much more readable, and concise build scripts. With Maven, build scripts are written using XML in pom.xml file which is very verbose, but with Gradle, build scripts are written using Groovy which is very concise by design. This means the same 100 line Maven build script can be replaced by 10 to 20 lines of Gradle script. To give you an exam, here is a diagram that compares a Gradle script to a Maven pom.xml file.

How to Loop Through An Array in Java with Example

Hello there, If you want to loop over an array in Java but not sure how to do that then you have come to the right place. Earlier, I have shared many Java array tutorials and the best Java courses for beginners, and today, I am going to teach you how to iterate over an array in Java. There are multiple ways to loop over an array in Java, like you can use a for loop, an enhanced for loop, a while loop, or a do-while loop. Since while and do-while needs a condition to terminate they often depend upon the content of the array like stop when the current element is null or even or odd etc. If you just want to iterate over an array to access each element like loop over an array and print each entry then you should use either for loop or the enhanced for loop.

Top 20 Algorithms Interview Questions for Programmers and Software Engineers

Or which one is better to start with Android development, Kotlin, or Java? I have already answered that question in my previous article, but I am still receiving a lot of queries about learning Kotlin and whether Java developers should Learn Kotlin or not?

Restful Web Services in Java using Jersey [Hello World Example]

Along with Spring Boot, Apache CXF, and  Restlet, Jersey is another popular open-source framework to create RESTful web services in Java. Jersey conforms to JAX-RS specification and actually it is the reference implementation of JAX-RS (JSR 311)( specification. In the last article, we have seen the Restlet HelloWorld Example and today we'll see the Jersey HelloWorld Example. Typically, when a developer thinks of creating a RESTful web service using Java, they assume that using a Java EE application server is the only way to create this type of application.

Mapping of HTTP Methods to RESTful Web Services Function in Java?

RESTful web services heavily rely on HTTP by design. They use different HTTP methods to perform their job and uses an HTTP response code to inform clients about the success or failure of a particular request. REST stands for Representational State transfer and it uses HTTP to allow two systems to communicate via remote calls. RESTFul web services are a collection of REST URI which points to resources. These URI can point to a single resource or a collection of resources. For example, you would expect /employee/101 to contain details of employees with 101 and /employees to return a list of all employees. In the RESTFul web service, HTTP request types signify the action to take for the resource.

Print Fibonacci Series in Java Using Recursion and For Loop

Printing Fibonacci Series In Java or writing a program to generate Fibonacci number is one of the interesting coding problems, used to teach college kids recursion, an important concept where function calls itself. It is also used a lot as coding problems while interviewing graduate programmers, as it presents lots of interesting follow-up questions as well. In the Fibonacci series, the next number is equal to the sum of the previous two numbers. First two numbers of series are always 1 and 1, third number becomes 1 + 1 = 2, subsequently fourth number becomes 2 + 1 = 3. So a Fibonacci series looks like 1, 1, 2, 3, 5, 8, 11, 19, and so on, as shown in the image as well.

Top 10 Dynamic Programming Problems for Coding Interviews

Dynamic Programming is one of the toughest concepts to master for programmers but at the same time, it's quite important to crack any programming job interviews. Nowadays, you will find at least one Dynamic programming coding problem on every coding interview and that's where most of the programmers get stuck. They try to solve the problem using techniques like divided and conquer but ultimately fail becuase it's difficult to come to a solution to such problems unless you have solved a decent number of dynamic programming-based coding questions. This is very similar to system design questions which look easy but when you try to solve them you often find yourself stuck and that's why I suggest you practice as much as possible.
