The following program implements and tests a length class that deals with feet$/$inches

measurements. It uses two private data members named feet and inches.

Feetlnches$\_02.$java

darr

In JAVA, Re$-$implement this class to use only one private data member, all$\_$inches.

The behavior of the class must be identical to the original implementation. You should change

only the Feetlnches class and not alter the public main class FeetInches$\_02$ at all. The results

using your modified should be identical to the results obtained from the original program.
