a constructor is a method in the class which gets executed when its object is created. Usually, we put the initialization code in the constructor. Writing a constructor in the class is damn simple, have a look at the following sample:

public class Test

{

    public Test()

    {

        //Initilize code in the constructor.
    }
}

• Constructors doesn't returns any value.
• References and pointers cannot be used on constructors and destructors because their addresses cannot be taken.
• Constructors cannot be declared with the keyword virtual.
• If the constructors is defined as private, we can not create instance of that class.

Method:

•  In methods we can define variables.These variables scope is within methods only.
• If you declare a public variable , it will be accessed in all mehtods.
• Methods may/maynot contains return type.
• Methods could be inhereted in derived class(Note That mehtod should be Public)

1. constuctor is a method of name ""same of class"" and is automatically called when the object of that class is created.
2. The methods aren't called when object is created,We have to call by using its class name.

Constructor is used to create an instance of  object.

Method is used to perform some operations.

1. constructor name should match with a class name, but for a method a name could be of anything.

2.constructor don't have any return type, where as a method can have a return type.
