Eate a class which is an iterator for the LinkedCollection. This class must implement the Iterator interface. You must think about what field(s) you need to keep track of the current element in the iteration, how to initialize the field(s), how to move to the next element, and how to know when all elements have been returned.

class CustomDataStructure implements Iterable<> {  

// code for data structure  

public Iterator<> iterator() {  

 return new CustomIterator<>(this);  

}  

}  

class CustomIterator<> implements Iterator<> {  

// constructor  

CustomIterator<>(CustomDataStructure obj) {  

 // initialize cursor  

}  

// Checks if the next element exists  

public boolean has Next() {  

}  

is that the whole question?
