Intro to Java programming

1. Complete Exercise 6.4, except change the name of the program from MultAdd.java to Functions as above. Carry out the instructions for testing parts 3-5 as given in the Exercise, including comments before your tests describing them.

Exercise Many computations can be expressed more concisely using the "multadd" operation, which takes three operands and computes a b+ c.Some processors even provide a hardware implementation of this operation for floating-point numbers 1 Create a new program called Multadd.java 2. Write a method called multadd that takes three doubles as parameters and that returns a bc 3. Write a main method that tests multadd by invoking it with a few simple parameters, like 1.0, 2.0, 3.0. 4. Also in main, use multadd to compute the following values: cos- sin-4 4 2 logio +log20 5. Write a method called expSum that takes a double as a parameter and that uses multadd to calculate: Hint: The method for raising e to a power is Math.exp In the last part of this exercise, you need to write a method that invokes another method you wrote. Whenever you do that, it is a good idea to test the first method carefully before working on the second. Otherwise, you might find yourself debugging two methods at the same time, which can be difficult. One of the purposes of this exercise is to practice pattern-matching: the ability to recognize a specific problem as an instance of a general category of problems
