# Multiplication Table in Java

The multiplication table in Java is a fundamental concept for beginners, aiding in understanding arithmetic operations and loop structures. It involves generating a grid of numbers representing the products of two factors. Through simple code, it fosters comprehension of iteration and mathematical principles, serving as a cornerstone in programming education.

## Multiplication table in Java- Code

```// Multiplication table in Java
import java.util.Scanner;
public class Multiplication_Table {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);

System.out.print("Enter number:");
int n=s.nextInt();
for(int i=1; i <= 10; i++) {
System.out.println(n+" * "+i+" = "+n*i);
}
}
}```

Explanation of the code-

Here is the explanation of the above given Java code for generating a multiplication table:

1. Import Necessary Packages: The code starts by importing the `Scanner` class from the `java.util` package to facilitate user input.

2. Define the Class: The class `Multiplication_Table` is defined to encapsulate the functionality of the program.

3. Main Method: The `main` method is declared as the entry point of the program.

4. User Input: A `Scanner` object `s` is created to read user input. The user is prompted to enter a number for which the multiplication table needs to be generated.

5. Loop for Multiplication Table: A `for` loop is used to iterate from 1 to 10. Within each iteration:

– The product of the input number (`n`) and the loop counter (`i`) is calculated (`n * i`).

– The result is printed in the format `n * i = result`.

6. End of Program: Once all multiples are printed, the program execution ends.

This code efficiently generates a multiplication table for the input number provided by the user, displaying the results up to the 10th multiple.

#### Output:

``Enter number:66 * 1 = 66 * 2 = 126 * 3 = 186 * 4 = 246 * 5 = 306 * 6 = 366 * 7 = 426 * 8 = 486 * 9 = 546 * 10 = 60``

## Customization Options

You can customize the program to generate multiplication tables of different sizes or start from different numbers by adjusting the input parameters and loop conditions.

1. Customizing Table Size: To generate a multiplication table of a different size, users can modify the loop condition in the `for` loop. For example, to generate a table up to the 12th multiple, change `i <= 10` to `i <= 12`.

2. Customizing Starting Number: Users can also customize the starting number of the multiplication table by changing the initial value of the loop counter (`i`). For instance, to start the table from the 5th multiple, initialize `i` to 5 instead of 1.

3. User Input: Alternatively, users can prompt for input to specify the size of the table and the starting number dynamically. To achieve this, read input from the user for these parameters and utilize them in the loop conditions and calculations.

4. Modularization: For better code organization and reusability, consider encapsulating the multiplication table generation logic into a separate method. This
