Database Concept - What are the main components when designing an ERD?
Network Protocols - Why are network protocols needed? How do you decide which protocol is more suitable for a network implementation?
Java Calculator - The Programming Example: Calculator in Chapter 12 is designed to do operations on integers. Write a similar program that can be used to do operations on decimal numbers. (Note: If division by zero occurs with values of the int data type, the program throws a division by zero exception. However, if you divide a decimal number by zero, Java does not throw the division by zero excep...
Java Class Fraction - Rational fractions are of the form a / b, where a and b are integers and b != 0. In this exercise, by "fractions" we mean rational fractions. Suppose a / b and c / d are fractions. Arithmetic operations on fractions are defined by the following rules:
a/b + c/d = (ad + bc) / bd
a/b - c/d = (ad - bc) / bd
a/b * c/d = ac / bd
(a/b) / (c/d) = ad / bc Hint: Chec...
