For abstarct class we can't create an object then what is the use of default contructor?

we can create an instance of the abstract class. But my doubt is constructor is exectuting whenever an object is creating of the particular class. when we inheriting the abstract class that time we are implementing the unimplemented methods. So eventhough we can't able to create an object of the abstract class,then what is use of the constructor and when it is executing. Please let me know the answer for this if anyone knows........
