I was trying to write a generic function that converts a value to a generic type:

public static <T> T toType(Object value, Class<T> tClass) {
try {
T obj = tClass.newInstance();
return obj;
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}

it gives me InitiationException why?

InitiationException? Did you mean InstantiationException? The API documentation of InstantiationException explains when this exception can happen (look it up).

Is the type you are calling this with a concrete type (not an abstract class or an interface)? Does the type have a no-arguments constructor?
