Design and implement a class called MonetaryCoin that is derived from the Coin class presented in Chapter 5. Store an integer in the MonetaryCoin that represents its value and add a method that returns its value . Add a toString method that appends a space followed by the coin's value to the Coin's String representation.

Driver. Instead of creating a main driver class , include a main method in the MonetaryCoin class itself to exercise the class 's behavior . Your method should create an array of 7 MonetaryCoin objects with values 1,5,10,25,50,100,100 and then iterate through the array , flipping in each coin. The method should then iterate through the array again, invoking the getValue method and adding up the resulting values . The String representation of each coin should then be printed on a line by itself, followed by, on a line by itself, the sum of the values that was computed (preceded by the label "Total Value : "
