Hi,
I would like to create an instance of a specified class using its name. My code is shown below.
I get a compiler warning. Am I doing this the right way? Is it even possible to use the name of a class and get an instance of that type back, as I don't think there is any way of the compiler knowing what the type should be?
public static <T> T create(final String className) {
try {
final Class<?> clazz = Class.forName(className);
//WARNING: Type safety: Unchecked cast from capture#2-of ? to T
return (T) create(clazz);
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
public static <T> T create(final Class<T> classToCreate) {
final Constructor<T> constructor;
try {
constructor = classToCreate.getDeclaredConstructor();
final T result = constructor.newInstance();
return result;
}
catch (Exception e) {
e.printStackTrace();
}
}
Thanks
