Create two classes (A and B) with A has an abstract method ( void call ( )) and B extends from A. Class A has a concrete method callA ( ) that displays “concrete method callA() in A”. B is a concrete class. Your AbstractDemo (client) program should display the following: B’s implementation of A's call( ) . concrete method callA( ) in A

Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. after the loop terminates, it prints out, on a line by itself and separated by spaces, the sum of all the even integers read, the sum of all the odd integers read, a count of the number of even integers read, and a count of the number of odd integers read, all separated by at least one space. declare any variables that are needed. assume the availability of a variable, stdin, that references a scanner object associated with standard input. that is, stdin = new scanner(system.in); is given.
