How to do this in Java it needs to be in 2 classes a Tester class that has the main and a 2nd class with the methods

*** P8.7 For faster sorting of letters, the U.S. Postal Service encourages companies that send large volumes of mail to use a bar code denoting the ZIP code (see Figure 8). *************** ECRLOT ** COS7 CODE C671 RTS2 JOHN DOE 1009 FRANKLIN BLVD SUNNYVALE CA 95014-5143 C057 ILLULLLLLLL Figure 8 A Postal Bar Code The encoding scheme for a five-digit ZIP code is shown in Figure 9. There are full height frame bars on each side. The five encoded digits are followed by a check digit, which is computed as follows: Add up all digits, and choose the check digit to make the sum a multiple of 10. For example, the sum of the digits in the ZIP code 95014 is 19. so the check digit is I to make the sum equal to 20. Frame bars ILL.

Note that they represent all combinations of two full and three half bars. The digit can be computed easily from the bar code using the column weights - Each digit of the ZIP code, and the check digit, is encoded according to the table at right, where o denotes a half bar and 1 a full bar. Note that they represent all combinations of two full and three half bars. The digit can be computed easily from the bar code using the column weights 7. 4, 2, 1, 0. For example, 01100 is OX 7+1 X 4+1 X 2 + OXI+OX0 = 6 The only exception is o, which would yield 11 according to the weight formula.

Your program should also be able to carry out the opposite conversion: Translate bars into their ZIP code, reporting any errors in the input format or a mismatch of the digits
