		}
		int joined()
		{
			double c, i = 0;
			int n;
			c = a;
			n = b;
			do
			{
				n = n / 10;
				i++;
			}while(n != 0);
			a = (int)(c * Math.pow(10, i)) + b;
			return(a);
		}
		void display(int p)
		{
			System.out.print("\n The concatenate number = "+p);
		}
	public static void main(String arg[])
	{
		Concatenate s = new Concatenate();
		int p;
		p = s.joined();
		s.display(p);
	}
};
