Question

Create java Class with name Conversion.

Instructions for Conversion class:

The Conversion class will contain methods designed to perform simple conversions. Specifically, you will be writing methods to convert temperature between Fahrenheit and Celsius and length between meters and inches and practicing overloading methods.

See the API document for the Conversion class for a list of the methods you will write.

Also, because all of the methods of the Conversion class will be static, you should ensure that it is not possible to create any instances of the class. You can do this by declaring a default constructor method using the private access modifier.
