RandomDataGenerator | configurable generator to create random data | Generator Utils library

CovidData *data[] is grouped as CovidData *(data[]), so it declares an array of pointers to CovidData. For a pointer to an array, you would use CovidData (*data)[].

However, we rarely pass a pointer to an array. Usually, it is sufficient and convenient merely to pass a pointer to the first element. Thus, you would declare the parameter as CovidData *data and pass it as RandomDataGenerator(data, 2).

If you did declare the parameter as a pointer to an array, you would not use it with data[i]->region. You would need *data to get the array before applying the subscript, and again you would need parentheses for correct grouping: (*data)[i]->region.

How App.java is running perfectly fine without importing DefaultRandomGenerator class from SubProject-2

It works because they are both in the same package (org.examples).

Note that this will not work if using the new module system introduced in Java 9. Because the two projects are considered "split", and you will need various hacks to make it work.

Why am I getting the error message "No candidates found for method call api" in build.grade file of Parent project (MultiProjectApp).

This is an IDE problem, not a gradle problem. If you run, it should still work.
