Problem at JUnit test with generics
- by Tom Brito
In my utility method:
public static <T> T getField(Object obj, Class c, String fieldName) {
try {
Field field = c.getDeclaredField(fieldName);
field.setAccessible(true);
return (T) field.get(obj);
} catch (Exception e) {
e.printStackTrace();
fail();
return null;
}
}
The line
return (T) field.get(obj);
gives the warning "Type safety: Unchecked cast from Object to T";
but I cannot perform instanceof check against type parameter T,
so what am I suppose to do here?
