# Java Static Initializer Block HackerRank Solution

In this Java Static Initializer Block HackerRank Solution, Static initialization blocks are executed when the class is loaded, and you can initialize static variables in those blocks.

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  and height . You should read the variables from the standard input.

If  or  , 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 : the breadth of the parallelogram. The next line contains : the height of the parallelogram.

Constraints

Output Format

If both values are greater than zero, then themainmethod must output the area of theparallelogram. Otherwise, print“java.lang.Exception: Breadth and height must be positive”without quotes.

Sample input 1
