How to get last digit of a number in java - Java Program to Find the Last Digit of a Number

How to get last digit of a number in java: In the previous article, we have seen Java Program to Find the First Digit of a Number

In this article we will see how to find the last digit of a number using Java programming language.

Java Program to Find the Last Digit of a Number

The digit at the end of a number is called as last digit.

For example:

A number is 7912

So, the last digit of a number is 2.

Let’s see different ways to find the last digit of the number.

By Using Static Input Value
By Using User Input Value
By Using User Defined Method

Method-1: Java Program to Find the Last Digit of a Number By Using Static Input Value

Approach:

Declare an integer variable say ‘num‘ and initialize a value.
Then find the number’s modulo by 10 which is the last digit of number.
Print the result.

Program:

public class Main
{
    public static void main(String[] args) 
    {
        //a number declared
        int num=591;
    
        //find last digit of the number
        int lastDigit = num % 10;
        
        System.out.println("Lasa Digit: "+ lastDigit);
 
    }
}

Output:

Lasa Digit: 1

Method-2: Java Program to Find the Last Digit of a Number By Using User Input Value

Approach:

Declare an integer variable say ‘num‘ and take the value as user input.
Then find the number’s modulo by 10 which is the last digit of number.
Print the result.

Program:

import java.util.Scanner;

public class Main
{
    public static void main(String[] args) 
    {
        //Scanner class object created
        Scanner sc=new Scanner(System.in);
        //taking a number input from user
        System.out.println("Please enter a number: ");
        int num=sc.nextInt();
    
        //find last digit of the number
        int lastDigit = num % 10;
        
        System.out.println("Lasa Digit: "+ lastDigit);
    }
}

Output:

Please enter a number: 
785
Lasa Digit: 5

Method-3: Java Program to Find the First Digit of a Number By Using User Defined Method

Approach:

Declare an integer variable say ‘num‘ and take the value as user input.
Call a user defined method findLast() and pass ‘num‘ as parameter.
Inside method find the number’s modulo by 10 which is the last digit of number.
Print the result.

Program:

import java.util.Scanner;

public class Main
{
    public static void main(String[] args) 
    {
        //Scanner class object created
        Scanner sc=new Scanner(System.in);
        //taking a number input from user
        System.out.println("Please enter a number: ");
        int num=sc.nextInt();
        //calling a user defined method findLast()
        findLast(num);
    }
    
    //user defined method findLast() to find last digit of number
    public static void findLast(int num)
    {
        //find last digit of the number
        int lastDigit = num % 10;
        
        System.out.println("Lasa Digit: "+ lastDigit);
    }
}

Output:

Please enter a number: 
568
Lasa Digit: 8
