#Coding Exercise ##Abstract

The exercise is broken in 3 parts, as described below. When you are done, follow these steps to delivery your answers.

• Create a new repository in Github, and upload your entire project, with the code you wrote, into Github
• Send us the URL to the repository
• Note, we should be able to clone your repo and compile all code in the project you created.

##Exercises

1. Write Unit tests, using any test framework, for the Java class below

package com.s5a.interview;

public class Product {

	private String brandName;

	public Product(String brandName) {
		this.brandName = brandName;
	}

	public String getBrandName() {
		return brandName;
	}

}

2. Write one Service class that provides integration to the DAO layer UserDAO class, according to the resources section at very bottom of this page. Write unit tests that you think are needed to make sure the Service class is bug free

3. Perform a code review and write your recommendations to the code below. Note, there are lots of missing parts and we expect you call out them. +1 (as bonus) if you refactor the code, in a new class, and make the compilation passes.

package com.s5a.interview;

public class ProductController {

	Product product = ServiceProduct.add("Saks-brand-name");

	private String showProduct() {
		product.getBrandName()
	}

	public boolean addProduct(String brandName) {
		product = serviceProduct.add(brandName);
		
		return true;
	}

	public static void formatedBrandName() {
		System.out.println("Current product: " + product.getBrandName)
	}

}

Look at Resources section below for references that you may need to accomplish the exercises.
