Returns true if the iteration has more elements.

Usage

From source file:Main.java

public static void main(String[] args) {
    LinkedHashMap<String, String> lHashMap = new LinkedHashMap<String, String>();

    lHashMap.put("1", "One");
    lHashMap.put("2", "Two");
    lHashMap.put("3", "Three");

    Set st = lHashMap.keySet();//from  w  w w  .j a v  a2  s . com

    Iterator itr = st.iterator();

    while (itr.hasNext()) {
        System.out.println(itr.next());
    }
    st.remove("2");

    boolean blnExists = lHashMap.containsKey("2");
    System.out.println(blnExists);
}

From source file:Main.java

    List src = new LinkedList();
    for (int i = 0; i < coins.length; i++) {
        src.add(coins[i]);//from   ww w.  jav  a  2s  .c  o  m
    }

    System.out.println(src);

    Collections.fill(src, "java2s.com");
