Can't find symbol. Constructor

[Noob.]

Hello pros :)
I'm trying to implement a simple program which uses a constructor.
Here's my code:

import java.io.*;

class add
{
	private int c;
	
	void add(int a, int b)
	{
		c = a + b;
	}	
	
	void display()
	{
		System.out.println("Result is " +c);
	}
}

class Mainn
{
	public static void main(String args[]) throws IOException
	{
		int x, y;
		BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));
		System.out.println("Enter 2 numbers: ");
		x = Integer.parseInt(obj.readLine());
		y = Integer.parseInt(obj.readLine());

		add o = new add(x, y);
		o.display();
	}
}

Here' my error:add_cons.java:28: cannot find symbol
symbol : constructor add(int,int)
location: class add
add o = new add(x, y);
^
1 error

I'm using Ubuntu. Java 1.7

Thanks,

A constructor doesn't have a return value in its signature...that includes 'void'.
so not:
void add(int x, int y) {etc.}
but
add(int x, int y) {etc.}

You don't have a constructor with 2 int arguments. I'm assuming that you think this is a constructor:

	void add(int a, int b)
	{
		c = a + b;
	}

...but that is actually just a method. A definition of a constructor uses the syntax: public className(type arg0, type arg1, type arg2, ....)

If I wasn't clear enough, check out this tutorial: Constructors

Not fast enough...

Oops. Not even void?! That was pretty noob

I remember reading that constructors implicitly return the object that is constructed, so explicitly stating that it returns no object would not make sense.
