Java to Find the Largest Number Among Three Numbers

//Java program to find greatest of three numbers
import java.util.Scanner;
public class greatest_of_three_numbers
{	
	public static void main(String[] args)
	{
		//scanner class declaration
		Scanner sc = new Scanner(System.in);
		//input three numbers from user
		System.out.print("Enter the first number : ");				
		int first = sc.nextInt();
		System.out.print("Enter the second number : ");
		int second = sc.nextInt();
		System.out.print("Enter the third number : ");	
		int third = sc.nextInt();
		System.out.println();
		//condition for first number
		if(first > second && first > third)							
			System.out.println(first+" is the greatest number.");
		//condition for second number
		else if(second > first && second > third)					
			System.out.println(second+" is the greatest number.");
		//condition for third number		
		else if(third > first && third > second)					
			System.out.println(third+" is the greatest number.");	
		//condition when all three numbers are equal
		else														
			System.out.println("All three numbers are same");
		//closing scanner class(not compulsory, but good practice)
		sc.close();
