Create JUnit tests for the calculateTaxRate (ProductType productType) and getDensityQualifier (int dpi) methods of the provided class SampleClass (described below). Your goal is to create JUnit tests that result in 100% code coverage.

Create JUnit tests for the calculateTaxRate(ProductType productType) method based upon the following requirements: Invoke this method by passing a ProductType (which is a public enum found in the SampleClass class). The method should return the appropriate tax rate as shown below. (The tax rate is returned as a decimal value).

Product Type	Tax Rate
Bakery	5%
Beverage	7.5%
Dairy	4%
Deli	6.5%
Meat	6.5%
Pharmacy	3.5%
Produce	4.5%
Seafood	6%

Create JUnit tests for the getDensityQualifier(int dpi) method based upon the following requirements: Invoke this method by passing an integer screen density value (referred to as dpi). The method should return the appropriate screen density qualifier value as shown below. (The screen density qualifier is returned as a String value).

Density Qualifier	Description
ldpi	Up to 120dpi
mdpi	Up to 160dpi
hdpi	Up to 240dpi
xhdpi	Up to 320dpi
xxhdpi	Up to 480dpi
xxxhdpi	Up to 640dpi
tvdpi	For televisions, exactly 213dpi
nodpi	Any other unspecified positive value
