Question
A. Write a Java class that declares a named constant that holds the number of feet in a mile : 5,280 . Also declare a variable to represent the distance in miles between your house and your uncle's house. Assign an appropriate value to the variable for example, 8.5. Compute and display the distance to your uncle's house in both miles and feet . Display explanatory text with the values for example . -The distastance to my uncle's house is 8.5 miles or 44880.0 feet. Save the class as MilesToFeet.Java.
B. Convert the MilesToFeet class to an interactive application. Instead of assigning a value to the distance, accet the value from the user as input . Save the revised class MilesToFeetInteractive.java.
