Usage

From source file:TComp.java

public static void main(String args[]) {
    TreeMap<String, Double> tm = new TreeMap<String, Double>(new TComp());

    tm.put("J D", new Double(3434.34));
    tm.put("T S", new Double(123.22));
    tm.put("J B", new Double(1378.00));
    tm.put("T H", new Double(99.22));
    tm.put("R S", new Double(-19.08));

    Set<Map.Entry<String, Double>> set = tm.entrySet();

    for (Map.Entry<String, Double> me : set) {
        System.out.print(me.getKey() + ": ");
        System.out.println(me.getValue());
    }//from  ww w.  ja  v  a  2s .c o m
    System.out.println();

    double balance = tm.get("A");
    tm.put("A", balance + 1000);

    System.out.println("A's new balance: " + tm.get("A"));
}

            .collect(Collectors.collectingAndThen(Collectors.groupingBy(p -> p.getDob().getMonth(),
                    Collectors.mapping(Employee::getName, Collectors.joining(" "))), result -> {
                        for (Month m : Month.values()) {
                            result.putIfAbsent(m, "None");
                        }/*from   www. j a v  a  2s . co m*/
                        return Collections.unmodifiableMap(new TreeMap<>(result));
