Perceptron.java
:

1. Implement the Perceptron constructor, Perceptron(int n), and the method, int numberOfInputs().

a. Test: In the main() method, instantiate a few Perceptron objects and print the number of inputs for each object.

2. Implement the String toString() method.

a. Test: In the main() method, print the various Perceptron objects.  What should the output be for a newly instantiated Perceptron object?

3. Implement the double weightedSum(double[] x) method.

a. Test: In the main() method, print the result of invoking the weightedSum method on the various Perceptron objects (using, of course, appropriately sized arrays.

4. Implement the int predict(double[] x) method.

5. Implement the void train(double[] x, int label) method.  Note - train should call predict.
