    Default University project - Library Program.

    Hello everyone.
    I am kinda a beginner, been java programming for 3-4 months, but i learn fast.
    I have a java programming project, a gui library system, something complex.
    User has to create library, then add books, delete books, add chapters in book, remove chapter.

    First i have to do 6 classes( architecture, they name it):
    - class Library: contains objects of type Book and implements ILibrary
    - class Book: contains objects of type Chapter and book name and implements IBook
    - class Chapter: contains objects of type Paragraph and chapter name si and implements IChapter
    - class Sentence: extends ArrayList<String> and retain one sentence
    - class Paragraph: extends Body<Sentence> and retain one or more sentences, so a paragraph
    - class Body: implements Collection and can retain only objects of the same type in a ArrayList

    I did 3 classes for this 6. But i stuck at class Body, i did not learn about parameterized class, so i don't know how to declare it. Can someone help me with Body class and Paragraph class?

    Especially i stuck at build constructors. I don't know what to do with the <E> from Body

    package element;
     
    import java.util.ArrayList;
    import java.util.Collection;
    import java.util.Iterator;
     
    public class Body<E> implements Collection {
     
        private E item;
        private ArrayList<E> items = new ArrayList<E>();
     
        @Override
        public int size() {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean isEmpty() {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean contains(Object o) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public Iterator iterator() {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public Object[] toArray() {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public Object[] toArray(Object[] a) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean add(Object e) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean remove(Object o) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean containsAll(Collection c) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean addAll(Collection c) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean removeAll(Collection c) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public boolean retainAll(Collection c) {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
        @Override
        public void clear() {
            throw new UnsupportedOperationException("Not supported yet.");
        }
     
    }

    I'm a still a student and a beginner in java, so please bear with me.

    Default Re: University project - Library Program.

    Nobody can help me with this class? I can't find a convincing example with parameterized class.
