#Question. #Can #we #place #only #parameterized #constructor #in #our #servlet #class? #Adv #Java #Servlet #programming #Tutorial #advance #java #tutorial #interview #question #servlet:
Note: If there are no costructor in our java class then the java compiler creates one zero parameter constructor as default constructor. This default constructor will not be generated if that java class contains explicitly placed user defined constructor.
Servlet container always creates our servlet class object by using zero parameter, so make sure that our servlet class is having zero parameter constructor directly(explicitely placed by programmer) or indirectly(java compiler generated zero parameter constructor).
Answer : Not possible, because the servlet container can not create the object for our servlet class by using parameterized costructor.
