Write a program to print the multiplication table of the number entered by the user.
Here’s a simple Java program that prints the multiplication table for a number entered by the user:
import java.util.Scanner;
public class MultiplicationTable {
public static void main(String[] args) {
// Create a Scanner object to read input from the user
Scanner scanner = new Scanner(System.in);
// Prompt the user to enter a number
System.out.print("Enter a number: ");
int number = scanner.nextInt();
// Print the multiplication table for the entered number
System.out.println("Multiplication table for " + number + ":");
for (int i = 1; i <= 10; i++) {
System.out.println(number + " x " + i + " = " + (number * i));
}
// Close the scanner
scanner.close();
}
}
Explanation
- Importing Scanner Class: The
Scannerclass fromjava.utilpackage is imported to read input from the user. - Creating Scanner Object: A
Scannerobject namedscanneris created to read input from the standard input stream (keyboard). - Prompt User for Input: The program prompts the user to enter a number.
- Read the Input: The entered number is read and stored in the variable
number. - Print Multiplication Table: A for-loop is used to iterate from 1 to 10, and in each iteration, the multiplication result is printed in the format:
number x i = result. - Close the Scanner: Finally, the
scannerobject is closed to free the associated resources.
How to Run the Program
- Copy the code into a file named
MultiplicationTable.java. - Open a terminal or command prompt.
- Navigate to the directory containing the
MultiplicationTable.javafile. - Compile the program using the command:
javac MultiplicationTable.java - Run the compiled program using the command:
java MultiplicationTable - Enter a number when prompted, and the multiplication table for that number will be displayed.
Out Put
Enter a number: 5
Multiplication table for 5:
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50
Explanation of the Output
- User Input Prompt: The program prompts the user with
Enter a number:. - User Input: The user types
5and presses Enter. - Multiplication Table: The program then prints the multiplication table for the number
5, from5 x 1to5 x 10.
This output matches the behavior described in the program: it reads an integer from the user, and then prints out the multiplication table for that integer. Each line of the multiplication table shows the result of multiplying the input number by the current value of the loop variable i, which ranges from 1 to 10.
