auditing in java application

One of the goals of cloud computing is to allow developers to reduce the complexity of understanding and managing the hardware and software infrastructure so that they can focus on the functionality of the application. This goal has been achieved to varying degrees through the infrastructure, the service (IaaS) cloud and Peace Platform (PaaS) cloud. The IaaS cloud provides hardware and allows you to carry your own software. The PaaS Cloud also provide

Arrays class you have mastered it, let's examine it. An array hobbys is defined in the editor, please fill in the code in 2, 11, line, and implement the sort using the Arrays class and convert the output. The results of the operation are: [game, movie, sports] Import the Arrays class import java.util.Arrays; public class HelloWorld {public static void Main (string[] args) { //define an array of strings string[] Hobbys = {"Sports", "Game", "movie"}; Use the sort ()
