The homework is to put several methods in a "class" file. I dont know how to put all those in a "class". Here is the instructions.

"1. a method that takes a String and a character as input arguments and returns the number of occurrences of that character in the String.

2. a method that takes two Strings as input arguments and returns the number of occurrences of the second String in the first String.

3. a method that takes an integer number as an argument and returns true if it is a perfect square number. A perfect square is a number that has an integer as its square root. Do not use any of the Math methods to solve this. You may only use the primitive math operators "+, -, /, *, and %".

4. a method that takes an integer number as an argument and returns true it is a prime number. A Prime number is a number that can only be divided evenly by itself and 1. You may only use the primitive math operators "+, -, /, *, and %".

5 a method that takes an integer number as an argument and returns its factorial (x!) value. The factorial (x!) value of a number is that number multiplied by all of the whole numbers in it. 4! = 4 * 3 * 2 * 1. Note: 0! = 1. You may only use the primitive math operators "+, -, /, *, and %".

6. a method that takes a double and an integer as arguments and returns the value of the first raised to the second. You may only use the primitive math operators "+, -, /, *, and %". Note: x^8 = x^3 * x^2 * x^3. For a little extra challenge, you also may want to consider the fact that if the power value is even you can reduce the number of multiplies that need to take place. 3^16 = (((3^2)^2)^2)^2

7. a MyMethods class that contains each of these methods.

8. a testDriver class that calls each of the methods from the MyMethods class."
