parameter example: dog years

public class parameterExample  {

    public static void main (String[] args) {

        int ruff = 10;

        dogYears (20);

        dogYears (7);

        dogYears (12);

         //  this wasn't talked in class but could be useful for extra credit

        dogYears (ruff);

    }

    public static void dogYears (int human_years) {

        int dog_years;

        dog_years = human_years * 7;

        System.out.println (dog_years);

    }

}

Homework - Lesson 3.1   Parameters

Due 9/30/2014

1. In eclipse, create a new class called “FirstnameLastnameHwk3_1”, where “FirstnameLastname” is your first name and last name.  Include a main method when you create your class.
2. Create a method called “computeSquare” that has 1 integer parameter.  The parameter variable name should be “square”
3. In computeSquare method, multiple “square” by itself and then println the result.
4. In your main method, call computeSquare 4 different times.  The first time, pass in the number 1.  The second time, pass in the number 2.  The third time, pass in the number 3.  The forth time, pass in the number 4.
5. Run your program, the results should be:

1

6. Extra Credit, in your main method, remove the previous calls to computeSquare and write a for-loop that will call computeSquare 4 times (make 4 a constant variable in main and name it “NUMBER_OF_SQUARES”).  Have the iterator start at 1 and pass the iterator as the parameter to computeSquare.
7. Run your program, the results should be:
