Update all values at a time in HashMap [closed]

Question

I have a HashMap with some Keys - Values.

On some condition I want to update all values to single value regardless of keys.

Is there any util or predefined methods to do this, without for loop?

Any suggestions?

Answer 1

if (yourCondition) { 
      for (Map.Entry<String, String> entry : map.entrySet()) {
          map.put(entry.getKey(), MY_VALUE);
      }
}

Or for java 8 or higher (without a loop)

if (yourCondition) { 
      map.replaceAll( (k,v)->v=MY_VALUE );
}
