Writing a long sequence of numbers in a code is a hard stuff to read. In the new feature introduced by JDK 7 we are now allowed to write numeric literals using the underscore character to break the numbers to make it easier to read. You can see how to use underscore in numeric literals […]
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, […]
In this example you’ll see how to copy a file using the new API provided in the JDK 7. The first step is to define the source and the target of the file to be copied. For this we can use the Path class. To create an instance of Path we use the Paths.get() method […]
This code snippet show you how to split string with multiple white-space characters. To split the string this way we use the "\s+" regular expression. The white-space characters include space, tab, line-feed, carriage-return, new line, form-feed. Let’s see the code snippet below: package org.kodejava.lang; import java.util.Arrays; public class SplitStringMultiSpaces { public static void main(String[] args) […]
