I was just doing some Java coding and I needed to check the values of a bunch of fields of an object (mostly numbers). Normally I’d just call and print each get() method if I just need to check a few fields, but the class I’m dealing with has over 30 fields and I need to check them all and there’s no way I’m doing over 30 print statements for each get() method!

A quick Google search led me to this StackOverflow post which has exactly what I was looking for:

ClassABC abc = new ClassABC();
for (Field field : abc.getClass().getDeclaredFields()) {
    field.setAccessible(true);
    String name = field.getName();
    Object value = field.get(abc);
    System.out.printf("%s: %s%n", name, value);
}
