Write a Java-program to print Factorial of upto N Numbers ?

Program

public class Main
{
    public static void main(String args[])
    {
        int x,n=5,fact=1;
        for(x=1; x<=n; x++)
        {  
            fact=fact*x; 
            System.out.println(x+" Factorial= "+fact); 
        }
    }
}	

1 Factorial= 1
2 Factorial= 2
3 Factorial= 6
4 Factorial= 24
5 Factorial= 120

Using CommandLine Arguments

public class Main
{
    public static void main(String args[])
    {
        int x,n,fact=1;
        n=Integer.parseInt(args[0]);
        for(x=1; x<=n; x++)
        {  
            fact=fact*x;  
            System.out.println(x+" Factorial= "+fact); 
        }
    }
}	

1 Factorial= 1
2 Factorial= 2
3 Factorial= 6
4 Factorial= 24
5 Factorial= 120

Using Scanner Class

import java.util.*;
public class Main
{
    public static void main(String args[])
    {
        int x,n,fact=1;
        Scanner s=new Scanner(System.in);
        System.out.println("Enter n value: ");
        n=s.nextInt();
        for(x=1; x<=n; x++)
        {  
            fact=fact*x; 
            System.out.println(x+" Factorial= "+fact); 
        }
    }
}	

Enter n value : 5
1 Factorial= 1
2 Factorial= 2
3 Factorial= 6
4 Factorial= 24
5 Factorial= 120
