Java: how to get Iterator from String [duplicate]

Answer 1

No direct way. Not difficult to code, though:

public static Iterator gimmeIterator(final String x) {
        Iterator it = new Iterator() {
            String str = x == null ? "" : x;
            int pos = -1; // last read
            public boolean hasNext() {  return(pos+1 <  str.length());  }
            public Character next() { pos++;  return str.charAt(pos);       }
            public void remove() {
                throw new UnsupportedOperationException("remove unsupported for this iterator");
            }
        };  
        return it;
    }
