1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false.  2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method must be boolean. The method has to return either true or false and that does not mean that it should print or return the strings "true" or "false) 3) The class must define a method called printDetails that prints the current details (using System.out.println) of the book club in the following format: The Ven: 50 shoppers. Capacity 150. Where "The Ven" is the book club's name; 50 shoppers are currently present and the club’s capacity is 150. Of course, different BookClub objects will have different names, number of clubbers and different capacities. (Take note of the spacing between the different parts, the punctuation, and the order of the things to be printed) Write a method called about that has a void return type and takes no parameter. When called, this must print: BookClub written by login where you must replace login with for instance: BookClub written by djb247
