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!
Bean Validation Unit Testing
Java Bean Validation example
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
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 IllegalMonitorStateException
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 explained
Single Responsibility Principle (SRP) is the most important of SOLID software design principles. In this post we explain it and show how to apply!
GCD in Clojure using Euclidean algorithm
In this post we’re going to implement calculation of Greatest Common Divisor GCD in Clojure using Euclidean algorithm for two and more numbers.
GCD in Java using Euclidean Algorithm
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.
Remove duplicates from List in Java
We show how to remove duplicates from List in Java. Choose implementation depending on circumstances and with expected performance.
Clojure transients – fast mutations in persistent world
Clojure transients is a great way to optimize performance sensitive code without leaving familiar Clojure world. In this post we show how to use them to boost performance.
Generate random numbers concurrently – ThreadLocalRandom
Until Java 7 there was no simple and effective way to generate random numbers concurrently. Here we show ThreadLocalRandom to generate random numbers in a thread-safe way.
