Java Program - Multiplication Table

Concept Explanation

What is it?

This program takes an integer input from the user and prints its multiplication table from 1 to 10.

---

Algorithm

1. Start
2. Input a number n.
3. Start a loop from i = 1 up to 10.
4. Inside the loop, calculate product = n * i.
5. Print the result in the format "n * i = product".
6. End

Implementations

Java (JDK 17)

import java.util.Scanner;

public class MultiplicationTable {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter a number: ");
        int n = sc.nextInt();

        System.out.println("Multiplication Table for " + n + ":");
        System.out.println("---------------------------");

        for (int i = 1; i <= 10; i++) {
            System.out.println(n + " x " + i + " = " + (n * i));
        }

        sc.close();
    }
}
