CS101: Lab #1I
Writing Classes (Methods) II
Each of the following methods should be static and defined in a class called Utilities.
Implement a second class called Tester that calls each of these methods.
1. Write a method that returns the absolute value of a given integer; your implementation may not use
Math.abs.
2. Write a method that returns n! given an integer n. Your method must use and return a
BigInteger object. Note, you may need code like
act = fact.multiply (BigInteger.valueof (i)):
where i is an integer.
3. Write a method that returns a string consistent with the progression:
The method input should dictate the length of the pattern. For simplicity, interpret a negative value
positively; that is, use absolute value (your absolute value method, not Math.abs).
