Explanation / Answer

True Yes,a templete method in a templete method pattern is always concrete method. Beccause there will be a base class,which is will declare a concrete method. False When the super class is not having the default constructor and we are calling it from a sub class. then the error wont rise. It will call the constructor if it exists in the super class. If it is not there it simply search for it and ignore it. Thats why no error rises. True I coded the required example and run it. It safely ran wothout any errors. Hence we can define a class as abstract even if there are all concrete methods in it. True The given code is successfully compiled. The protected methods and members can be successfully accesed by the derived classes. hence the code compiles
