Constructor:
The class name and the method name are same. When you create an object for the class the method will be called directly. You don't want to call that method separately using that object.
Example:

C#

Class Praveen
{
public praveen
{

} 
}
class main
{
static void main()
{
praveen p=new praveen();  // the method will be called directly when you create the object.
}
}

Simply the Constructor is a function that will be called when you define an object of the class...
it mostly used for initiate data members and set default values.

Example:

class Student
{
    private int Id;
    Private String Name;

    private Student()
    { 
       Id = 0;
       Name = "ABC";
    }
}

So now when ever you create a Student Object it will take the default values.
