      Write a complete Java program that prompts the user to enter the following data:

• The customer name

• The customer address

• The customer category

• The units used

Then, the program will calculate the amount due and print the bill. This process will continue as many as the user wishes and will terminate when the user requests to stop.

Upon stopping the billing process, the program will generate a report that displays the following information:

• The total number of customers in each category

• The total collection in each category

• The total collection for the CityPhone Telephone Company

Write a program that has these overloaded search methods to do array searching:

boolean search(int[] arr, int searchKey) – searches an integer array given a search key value, returns true if searchKey is found, false if not.

Hint:

boolean found=false;

for(int i=0; i<arr.length; i++){

   if(    ){//compare the array element with the search key value

      //action taken if found

   }

}

//return something

boolean search(String[] arr, String searchKey) – searches an array of strings given a search key value, returns true if searchKey is found, false if not.

(read Comparing_Strings.doc)

In the main method, you can declare and initialize the two arrays with random values, for example:

int[] intArray={7,3,2,8,1,0,9};

String strArray={"Enchanted","Bedazzled","Divine","Delighted","Elegant"};

Use the methods in the program.
