Changing the values of a map.

[Onra]

Hello,

I have a variable which is of the type map with integers as keys and integers as values.

Now I want to write following method:

public static void changeValues(int n){
 //multiply the values of the map by n
}

I have no idea how to do that. Can anyone help me?

I'd get the keys out of the map via the keySet() method, then iterate through the map using this, getting the values, multiplying them and then putting them back in the map.

for e.g.,

    HashMap<String, Integer> map = new HashMap<String, Integer>();
    map.put("Mon", 1);
    map.put("Tues", 2);
    map.put("Wed", 3);
    map.put("Thurs", 4);
    map.put("Fri", 5);

    int multiplier = 5;
    System.out.println(map);
    for (String key : map.keySet()) {
      int value = map.get(key);
      value *= multiplier;
      map.put(key, value);
    }
    System.out.println(map);
