I have 2 or more enums with the same methods in each. I need to use all these enums to validate a message in another class. Each enum have the same methods. I understand how to pass an enum as a generic parameter but I don't believe it is then possible to call that enum's method in the method that receives the enum as a generic enum.

Just like other classes, enums can implement interfaces.
interface CanThing {
void doThing();
}
enum Validate implements CanThing {
ONE_THING {
@Override
public void doThing() {
System.out.println("One thing");
}
},
OTHER_THING;
// Default.
@Override
public void doThing() {
System.out.println("No thing");
}
}
public void doAThing(CanThing thing) {
thing.doThing();
}
public void test(String[] args) {
for (CanThing t: Validate.values()) {
doAThing(t);
}
}
