Can we place only parameterized constructor in our Servlet class?

By Dinesh Thakur

No, Because Servlet container uses 0-param constructor of our Servlet class that create the object of our Servlet class. If 0-param constructor (default constructor) not available then the Servlet container throws: java.lang.InstantiationException.

Note: If there are no constructors in java class then compiler generates 0-param constructor in that class as default constructor during compilation. Otherwise this default constructor will not be generated.
