Hi Friend,

Yes. But Abstract class constructors will be called when its concrete subclass will be instantiated.

For ex:

abstract class MyAbstractClass {

MyAbstractClass(){

System.out.println("I am abstract class constructor");
}

public abstract void show();
public void display(){
System.out.println("display() method in Abstract Class");
}
}

public class Value extends MyAbstractClass{
public void show() {
System.out.println("I am show method");

}
public static void main(String[] args) {

MyAbstractClass cl = new Value();
cl.display();
cl.show();
}
}

Thanks
