How can I initialise a static Map?

Question

How would you initialise a static Map in Java?

Method one: static initialiser
Method two: instance initialiser (anonymous subclass) or some other m

Answer 1

I would never create an anonymous subclass in this situation. Static initializers work equally well, if you would like to make the map unmodifiable for example:

private static final Map MY_MAP;
static
{
    MaptempMap = new HashMap();
    tempMap.put(1, "one");
    tempMap.put(2, "two");
    MY_MAP = Collections.unmodifiableMap(tempMap);
}
