hi
i want to sort map according to its key value
plz see code below
public static void main(String[] args) {
SortedMap map = new TreeMap();
// Add some elements:
map.put("2", "Two");
map.put("1", "One");
map.put("5", "Five");
map.put("4", "Four");
map.put("3", "Three");
map.put("10", "Ten");
map.put("12", "Twelve");
map.put("7", "Seven");
map.put("9", "Nine");
Iterator iterator = map.keySet().iterator();
while (iterator.hasNext()) {
Object key = iterator.next();
System.out.println("key : " + key + " value :" + map.get(key));
}
}
Result Should come below
key : 1 value :One
key : 2 value :Two
key : 3 value :Three
key : 4 value :Four
key : 5 value :Five
key : 7 value :Seven
key : 9 value :Nine
key : 10 value :Ten
key : 12 value :Twelve
