Can this work?

Question

Will this piece of code create a new object accordingly? I was wondering how to set the methods and the variables properly.
     AirplaneList plane = new AirplaneList();
     plane.add(); //Add planes to list
     plane.remove(); //Remove planes from list
     plane.empty();
     plane.full();
     plane.item();
     plane.total();
     //creating a new list
//if(!plane.isFull());
//plane.add("Boing 747");
//plane.add("Chesna");
//plane.add("StealthBomber");
     class Airplanelist
     //Attributes of the class
     private boolean isEmpty = true; //change list state
     private boolean isFull = false;
     private int getTotal;
     //Methods of the class
     public void add(String flight);
     //add the plane to a list or array or something
     System.out.println("INSANITY LEVEL APPROACHING CRITICAL HOW TO ADD A PLANE FROM LIST?");
     public void remove(String plane);
     //remove the plane to a list or array or something
     System.out.println("INSANITY LEVEL APPROACHING CRITICAL HOW TO REMOVE A PLANE FROM LIST?");
     //evaulate if list is empty
     public void empty() //List is empty
     isEmpty = true; //list state
     isFull = false;
     System.out.println("Is empty");
     }// empty()
     //evaulate if list is full
     public void full() //List is full
     isEmpty = false; //change list state
     isFull = true;
     System.out.println("Is empty");
     }// full()
     public void item(String int);
     //returns the airplane flight number
     System.out.println("return item number");
     public void total(String int);
     //returns the total number of airplanes on the list
     }//Airplane list class

I am aware Java is case-sensitive i have corrected the error. From what I have read a constructor initiates an object with a certain set of values for its variables/attributes. However it will not return a value? If there is no constructor present then java automatically assigns "false" values to the variables?
Learning is such a painful process. The coursework that has been set to me is to develop a "AirplaneListTester" class that has been partially created. I have already changed the case values from numbers to letters, so that the user will see a menu. It accepts both case-types and any other letter not listed will create an invalid response. This project appears very similar to the java cyberpet.
This is harder though because I have never dealt with more than two boolean conditions, i.e sleeping or eating. The user is to enter a flight number into the "add" plane menu, however I am not sure how to add planes let alone remove them yet, as well as print out all of the planes on the list and check to see how many there are already there.
EasyIn.getint method = size and size is an integer variable.
