In general we can use constructor to perform initialization activities but in old version of java(JDK1.0v), constructor can not accept dynamically generated class name as argument. To perform initialization of a servlet compulsory we should provide ServletConfig object as an argument whose class name dynamically generated by web container , as constructor can’t accept the dynamically generated class names hence, sun people ignored the constructor concept and introduced a specific method init(-) to perform initialization activities which can take dynamically generated class name as an argument.
