in School   public void addTeacherName classroom classroom  String teacherName        classroom setTeacherName teacherName       BTW  use Pascal Case for class names  Also  I would suggest a Map lt String  classroom gt  to map a classroom name to a classroom   Then  if you use my suggestion  this would work  public void addTeacherName String className  String teacherName        classrooms get className  setTeacherName teacherName

Instead of using this in your current class setClassRoomName  aClassName    you have to use classroom setClassRoomName  aClassName     You have to add the class  and at a point like  yourClassNameWhereTheMethodIs theMethodsName      I know it s a really late answer but if someone starts learning Java and randomly sees this post he knows what to do

Try this    public void addTeacherToClassRoom classroom myClassRoom  String TeacherName        myClassRoom setTeacherName TeacherName

You should capitalize names of your classes  After doing that do this in your school class    Classroom cls   new Classroom    cls setTeacherName newTeacherName     Also I d recommend you use some kind of IDE such as eclipse  which can help you with your code for instance generate getters and setters for you  Ex  right click Source -  Generate getters and setters
