Code in Java: please explain in details

Program Requirements:

Design a program that asks the user for a street number, type, and direction $($e$.$g$.,$ "North $4$th Street"$).$

Your program should then tell the user:

How many blocks east or west the street is from Central Avenue.

Whether the street is north or south of Washington Street.

The name of the preceding Avenue or Street $($closer to Central Avenue$)$ considering both direction and number.

Test the program to ensure it works correctly. The following examples can serve as a guide for the testing of the code.
