Question

The assignment this week is to spend some time creating a working implementation of the MixedFlatteningList interface.

Submit three .java files: The interface, your implementation, and any test code that you wrote.

Submit a short description of your process and the results in a .txt file.

public interface MixedFlatteningList {

  

  public MixedFlatteningList get(int index);

  

  public boolean isInt();

  public boolean isString();

  public boolean isCompound();

  

  public int getInt();

  public String getString();

  

  public  void clear();

  

  public void add(int value);

  public void add(String value);

  public void add(MixedFlatteningList value);

  

  public  void set(int value, int index);

  public  void set(String value, int index);

  public  void set(MixedFlatteningList value, int index);

  

  public  String toString();

  public  void flatten();

  public MixedFlatteningList toFlattened();

  public  boolean isFlat();

  public MixedFlatteningList clone();

}

Explanation / Answer

some of MixedFlatteningList Programm : public class FlattenIterator implements Iterator { private final Stack iteratorStack; private Object next; public FlattenIterator(List list) { if (list == null) { throw new NullPointerException(); } iteratorStack = new Stack(); iteratorStack.push(list.iterator()); } public void remove() { /* Not implemented */ } private void moveToNext() { if ((next == null) && !iteratorStack.empty()) { if (iteratorStack.peek().hasNext()) { final Object next = iteratorStack.peek().next(); if (next instanceof Iterator) { iteratorStack.push((Iterator) next); moveToNext(); } else if (next instanceof Iterable) { iteratorStack.push(((Iterable) next).iterator()); moveToNext(); } else if (next instanceof Array) { iteratorStack.push(Arrays.asList((Array) next).iterator()); moveToNext(); } else { this.next = next; } } else { iteratorStack.pop(); moveToNext(); } }
