Theory for this problem
+
The core idea of **Rectangle Area** is to model the requested operation directly: Two positive integers `a` and `b` are given. Print the rectangle area. The reference solution uses `Scanner` for input. Keep only the state needed for this result, choose numeric types that cover the stated bounds, and preserve the exact input/output contract. This makes the solution easier to verify on boundary cases and avoids unrelated work.

Hints
+
['Follow the statement for **Rectangle Area** literally and identify the smallest state needed to produce its output.', 'The reference solution relies on `Scanner` for input; test the smallest allowed input and one boundary case from the constraints.']

Solution

// CodeMaster — Rectangle Area
import java.util.*;
public class Main {
public static void main(String[] args) throws Exception {
Scanner sc = new Scanner(System.in);
int a = sc.nextInt();
int b = sc.nextInt();
int area = a * b;
System.out.println(area);
}
