Question

Ok so here is what I need to do:

I am reading in a CSV file and need to generate a new instance of a class for each line.

I then need to store the reference variable for the class in a List.

I am ok with most of this but how do I generate a class using a variable

something like this

string newClassName;
int a = 1; //counts number of loops

while (bufferedScanner.hasNextLine());
{
    newClassName = SS + a;

    LightningStorms newClassName = new LightningStorms();

    a = a + 1;

}

I have left out a lot of extra code but its the setting up of the new class that I am interested in.

I am current learning and this is part of an assignment so want to figure most out for myself (there is a lot more to the question than this) but am stuck so any guidance would be very welcome.

Many thanks

You can get an instance of a Class object for a particular name using Class.forName() – this needs to be a fully qualified class, so java.lang.String not String.

With the class object, you can construct a new instance using reflection, see Class.getConstructor()
