Question

Can I define multiple static blocks?

If possible, why should I define muliple static blocks?

Answer 1

yes, you can also make multiple initialisation blocks.

This allows you to place code with the thing initialised.

private static final Map<String, String> map;
static {
   // complex code to initialise map
}

private static final DbConnection conn;
static {
  // handle any exceptions and initialise conn
}
