System.getProperties().setProperty("com.chaosinmotion.factorialalgorithm", "cachedAlgorithm"); System.out.println("5! = " + FactorialUtil.factorial(5)); } This implies that we need a hash map of algorithms that we pick from prior to creating our singleton inside the factorial method. So we...

While writing the code, sometimes we need to print the space. For example, print space between the message and the values, print space between two values, etc. In the Python programming language, it's easy to print the space.Following are the examples demonstrating how to print the spaces ...
In the example of a factorial method, a parameter can be the number whose factorial we need to find. But what if we need to pass an entire array to a method? In the method declaration, we need to tell Java that the method must accept an array of a certain data type to pass an ar...
The Java Developer’s Kit provides a set of demo applications that draw images using static, single-buffered, and double-buffered animation. First, we will show you the basics of drawing single images. In fact, two of the classes we developed earlier actually did everything you need to know...
