hi genius programmer,
I am working on my project on how to create an abstract class named book that includes private field for International Standard Book Number(ISBN), price, author and a protected field title. includes properties for each fields.(An ISBN is a unique number assigned to each published book . provide public get and set accessors for each field. create a subclass named TextBook that includes a private grade level field and a CoffeeTableSubclass that contains no additional fields. (note: you yourself have to decide your own data type and name field. in the subclass override the accessor method of the book's price so that TextBook must be priced between $20.00 and $80.00, inclusive and the CoffeeTableBook must be priced between $35.00 and $100.00, inclusive also provide get and set accessors for grade level field in the class named TextBook. overload constructors for all classes.

thanks

For research purposes and to assist students, the admissions office of your local university wants to know how well female and male students perform in certain courses. You receive input that contains female and male students' GPAs for certain courses. Due to confidentiality, the letter code f is used for female students; m is used for male students. Every entry consists of a letter code followed by a GPA (for example, f 3.9). The number of entries is unknown.

Write a program that computes and outputs the average GPA for both female and male students. Format your results to two decimal places. Make your program take all the input from the user, reading in the 'm' or 'f' character followed by the GPA decimal value.

Hint: you will be using a loop that loops an unknown number of times, like until the user enters the character 'q' or something. As you are looping, be computing the overall male and female GPA sums and how many GPAs you have entered (per male and per female). Then after your loop, compu

Consider the following code fragment.

static int foo(int i,int a[]) {

String s;

int j = i - i - 1;

if (a[j] > 2) then

s = s + "bar";

else

return 0;

{

Identify at least three language violations in this code. For each one, indicate whether it is a static error,

checked runtime error, or unchecked runtime error.
