This program is a sample of Java simple IO expressions and t

This program is a sample of Java simple I/O, expressions and type conversions. It will expect as input the three lines of input and produce the output as described below.

** please write using a tokenizer**

Format for output: All floating point output is formatted such that there are two places to the right of the decimal point.
