Define a class named Doctor whose objects are records for a clinic’s doctors. Derive this class from the class Person given in Listing 8.1. A Doctor record has the doctor’s name—defined in the class Person—a specialty as a string (for example Pediatrician, Obstetrician, General Practitioner, and so on), and an office visit fee (use the type double). Give your class a reasonable complement of constructors and accessor methods, and an equals method as well. Write a driver program to test all your methods.
This project is a simple variation of Practice Program 1. Note that two of the Doctor constructors have the same two parameter types, String and double, but in opposite order, so they are clearly distinct to the compiler.
Given the following array, create a variable named product that will give the product of 4 * 5.
``` var nums = new Array(3,4,5,6,7,8,-99); ``` a. ``` var fives = new Array(); for (j = 1; j < 11; j++) fives[j] = j + 5; ``` b. ``` var fives = new Array(); for (j = 1; j < 11; j++) fives[j] = j * 5; ``` c. ``` var fives = new Array(); fives[0] = 0; for (j = 1; j < 10; j++) fives[j] = fives[j-1] + 5; ``` d. ``` var fives = new Array(); for (j = 0; j < 11; j++) fives[j] = fives[j] + 1; ```
