Constructor method, Can you easily solve the issue?

Question

I have had many problems intergrating a constructor method into my program. This is my first time programming in java, can someone please help me. I have contructed a class for an airplanelisttester, that allows the user choice to add or remove planes from the program using a switch method, i have yet to program each "case" accordingly, but i am having trouble at the start of the code. I need to create an "airplanelist" object, i have found some help on the internet, but i am not sure what is going wrong.
public class AirplaneListTester
     public static void main (String[] args)
throws java.io.IOException
          char choice;
          int size;
          size = EasyIn.getint();
     AirplaneList plane = new AirplaneList();
     plane.add(Airplane) = "Add a plane?";
     plane.remove(int) = "Remove a plane?";
     plane.isEmpty() = "Is Empty";
     plane.isFull() = "Is Full";
     plane.getitem(int) = "Airplanenumber";
     plane.getTotal() = "size" ;
     public AirplaneList
     private boolean add(Airplane);
     private boolean remove(int);
     private boolean isEmpty();
     private boolean isFull();
     private int getitem(int);
     private int getTotal();
     //..............rest of the program using swtich comands to alow the user to add\remove an airplane , check if a list is empty or      //full and display the list as well as exit the program.
}

Answer 1

ok so it should look a little like this? I am not really sure, on how to create these objects? ;-<. I understand that "isEmpty" and "isFull" should bounce back very obvious boolean statements, i.e. isfull or isempty. However I am not sure on what values to initiate for "add(Airplane)" ? Is that null? or should i prompt the user to enter one?

public class AirplaneList
     public static void main (String[] args)
throws java.io.IOException
          char choice;
          int size;
          size = EasyIn.getint();
     AirplaneList plane = new AirplaneList();
     plane.add(Airplane) = "Add a plane?";
     plane.remove(int) = "Remove a plane?";
     plane.isEmpty() = "Is Empty";
     plane.isFull() = "Is Full";
     plane.getitem(int) = "Airplanenumber";
     plane.getTotal() = "size" ;
//declaration
private boolean add(Airplane);
private boolean remove(int);
private boolean isEmpty;
private boolean isFull;
private int getitem(int);
private int getTotal;
//constuctor
public AirPlaneList
add(Airplane) = null;
remove(int) = null;
isEmpty = true;
isfull = false;
getitem(int) = size;
getTotal = null;      //initialisation
//methods
public boolean isFull()
return isfull;
public boolean isEmpty()
return isEmpty;
     //..............rest of the program using swtich comands to alow the user to add\remove an airplane , check if a list is empty or      
//full and display the list as well as exit the program.
