We don't have a method add() in HashMap.
We have put().
Map map = new HashMap(2);
map.put("1","one");
map.put("2","two");
map.put("3","three");
System.out.println("Size of the map="+map.size());
If we wrote like this, it will extend the size.
The out put is: Size of the map=3

Answer / raman t
if we write like this then it would be better.
HashMap map = new HashMap();
map.add( "cat", "Meow" );
map.add( "ape", "Squeak" );
map.add( "dog", "Woof" );
map.add( "bat", "Squeak" );
System.out.println( "map = " + map );
