Static Initializer Block Solution

The problem context is about validating the dimensions of a rectangle. In Java, it's common to use a static initializer block to initialize static fields. This block of code is executed when the class is loaded into memory. In this case, the static initializer block is used to validate the breadth (B) and height (H) of a rectangle.

Here is the Static Initializer Block Solution HackerRank solution using CodeRankGPT:

The solution approach is to use a static initializer block to validate the breadth and height of a rectangle. The block reads the breadth and height from the user input, checks if they are positive, and sets a flag to true if they are. If either the breadth or height is not positive, it throws an exception with a message indicating that both must be positive. The exception is caught and its message is printed to the console.

import java.util.Scanner;

/**

public class JavaStaticInitializerBlock {
	static Scanner sc = new Scanner(System.in);
	static int B = sc.nextInt();
	static int H = sc.nextInt();
	static boolean flag;
	static {
		try {
			if (B > 0 && H > 0) {
				flag = true;
			} else {
				throw new Exception("Breadth and height must be positive");
			}
		} catch (Exception e) {
			System.out.println(e);
		}
	}
}
