Hacker Rank Solution java

Static initialization blocks.

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 the main method. Complete the given code so that it outputs the area of a parallelogram with breadth B and height H. You should read the variables from the standard input.

 

If  B<=0 or H<=0, 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.

Solution:

import java.util.*;

import java.text.*;

import java.math.*;

import java.util.regex.*;

public class Solution {

static Scanner scan = new Scanner(System.in);

static int B = scan.nextInt();

static int H = scan.nextInt();

static boolean flag = true;

static{

    try{

        if(B <= 0 || H <= 0){

            flag = false;

            throw new Exception("Breadth and height must be positive");

        }

    }catch(Exception e){

        System.out.println(e);

    }

}

public static void main(String[] args){

        if(flag){

            int area=B*H;

            System.out.print(area);

        }

        

    }//end of main

}//end of class
