/* 
If B<=0 or H<=0, the output should be "java.lang.Exception: Breadth and height must be positive" without quotes.
If both values are greater than zero, then the main method must output the area of the parallelogram. Otherwise, print "java.lang.Exception: Breadth and height must be positive" without quotes.
