If you ever need to do this dynamically, you can use the following:
boolean isInstance(Object object, Class type) {
return type.isInstance(object);
}
You can get an instance of java.lang.Class by calling the instance method Object::getClass on any object (returns the Class which that object is an instance of), or you can do class literals (for example, String.class, List.class, int[].class). There are other ways as well, through the reflection API (which Class itself is the entry point for).
