Base class constructors are always called in the derived class constructors. Whenever you create derived class object, first the base class default constructor is executed and then the derived class's constructor finishes execution. While implementing inheritance in a Java program, every class has its own constructor. Therefore the execution of the constructors starts after the object initialization. It follows a certain sequence according to the class hierarchy.
