Static initialization blocks are executed when the class is loaded, and you can initialize static variables in those blocks.

It's time to test your knowledge of Static initialization blocks. You can read about it here.

You are given a class Solution with a main method. Complete the given code so that it outputs the area of a parallelogram with breadth [SVG image] and height [SVG image] . You should read the variables from the standard input.

If [SVG image] or [SVG image] [SVG image] , the output should be "java.lang.Exception: Breadth and height must be positive" without quotes.

Input Format

There are two lines of input. The first line contains [SVG image] : the breadth of the parallelogram. The next line contains [SVG image] : the height of the parallelogram.

Constraints

• [SVG image]
• [SVG image] Output Format

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.

Sample input 1
