How to edit a java map

Question

I have a simple question about a java map.Suppose I have a map that has a key and value already set. How do I change the value of that key; what method would I use?

Answer 1

Just call a normal put -- it will replace the existing value for the key. If you need to access the old value for that key, the put method returns it.

See the javadoc for more details.
