how to get a constant in java with class

Question

basically I need to get a constant for a class however I have no instance of the object but only its class. In PHP I would do constant(XYZ); Is there a similar way

Answer 1

To get private constant like:

private static final String BAR = "test";

you need to set it accessible first:

Field barField = Foo.class.getDeclaredField("BAR");
barField.setAccessible(true);
String bar = (String) barField.get(null);
