The JDK 7 add a small feature to work with a binary number. In the previous JDK we have to use the Integer.parseInt() method if we need to work with other base number. But with this new feature introduced in the Project Coin we can simplify the code when we work with the binary number. […]
The following code snippet will show you how to pick a random value from an enum. First we’ll create an enum called BaseColor which will have three valid value. These values are Red, Green and Blue. To allow us to get random value of this BaseColor enum we define a getRandomColor() method in the enum. […]
In Java 7 a new feature called diamond syntax or diamond operator was introduced. This diamond syntax <> simplify how we instantiate generic type variables. In the previous version of Java when declaring and instantiating generic types we’ll do it like the snippet below: List<String> names = new ArrayList<String>(); Map<String, List<Integer>> map = new HashMap<String, […]
