How to get a field with Reflection in Java

Today, while looking into server-less Wiremock, I wanted to retrieve a (private) field from a class.

Interestingly, most of the Stack Overflow posts I found weren't super helpful, but this reply from Lino on StackOverflow helped me track it down:

WireMockServer server = new WireMockServer();
try {
  Field field = WireMockServer.class.getDeclaredField("stubRequestHandler");
  field.setAccessible(true);
  handler = (StubRequestHandler) field.get(server);
  // yay!
} catch (NoSuchFieldException | IllegalAccessException e) {
  throw new RuntimeException(e);
}
