TODO item: Get ready for the next weekly Quiz by writing Exercise solutions as static methods in Eclipse. Copy your code from Practice-IT Exercises into a working java file, so you can keep your work organized and ready for whatever might follow (and it will). Submit Chapter3.java with at least the following five methods: 3.7 Write a method largest Abs Val that accepts three integers as parameters and returns the largest of their three absolute values. 3.9 Write a method named lastDigit that returns the last digit of an integer. 3.12 Write a method called scientific that accepts two real numbers as parameters for a base and an exponent and computes the base times 10 to the exponent, as seen in scientific notation. 3.16 Write a method called triangleArea that accepts the three side lengths of a triangle (all real numbers) as parameters and returns the area of a triangle with those side lengths. 3.17 Write a method padstring that accepts two parameters: a String and an integer representing a length. The method should pad the parameter string with spaces until its length is the given length. Of course you've done MANY more Exercises and Self-Check Problems, because you know that practice makes perfect, it's the best way to learn this stuff!!!
