In Java 8 interfaces default and static methods are major changes that allow to extend existing code without breaking anything. It should be the first step into Java 8.
javax.validation defines a number of Bean Validation Constraints for values of most commonly used types. In this post we’ll show how to use each of them!
In this article we present practical Bean Validation Unit Testing using JUnit. Testing this part is very simple, yet often neglected by many developers. Let’s fix that!
In this post we show Java Bean Validation example! Bean Validation is fantastic and flexible library that can be used in JEE and JSE programs to verify data!
java.lang.InterruptedException is thrown when a Thread blocked in Object.wait(), Thread.join(), or Thread.sleep() is interrupted. Here we’ll look at these cases.
java.lang.IllegalMonitorStateException form Object’s notify/wait methods indicates basic synchronization issue. In this post we’ll show the reason and how to fix it!
Single Responsibility Principle (SRP) is the most important of SOLID software design principles. In this post we explain it and show how to apply!
In this post we’re going to implement calculation of Greatest Common Divisor GCD in Clojure using Euclidean algorithm for two and more numbers.
In this post we show how to implement GCD in Java using Euclidean Algorithm. GCD is known as Greatest Common Divisor/Factor/Measure, Highest Common Divisor/Factor.
We show how to remove duplicates from List in Java. Choose implementation depending on circumstances and with expected performance.
