This should demonstrate how to solve it:
import java.lang.reflect.Field;
class Super {
private int i = 5;
}
public class B extends Super {
public static void main(String[] args) throws Exception {
B b = new B();
Field f = b.getClass().getSuperclass().getDeclaredField("i");
f.setAccessible(true);
System.out.println(f.get(b));
}
}
(Or Class.getDeclaredFields
for an array of all fields.)
Output:
5
