Suppose that someone has defined for us a class called Random. The interface is shown below. 

public class Random { public double nextDouble() { // ... } public int nextInt(int range) { // ... } }

 For each of the following parts, write a single line of Java code that does what is described by the sentence. (a) Declare r to be a reference variable of type Random and assign to r a Random object. (b) invoke the nextDouble method for object reference by r and have the result printed in a console window. (c) Declare n to be a variable of type int and assign to it the result of invoke the nextInt method for object reference by r with parameter 10
