Answer 1

You can have a list variable and store the data in it using Java class.

1. Create a variable with variable class list or collection.
2. Put in the variable expression the Java method which returns the list.

If you are using groovy same thing can be achieved Groovy Collection. Here's more if you want to learn about groovy collections .

For Example :

Have a parameter/variable in report

<parameter name="list_collect" class="java.util.List" isForPrompting="false">
  <defaultValueExpression><![CDATA[(new beandatasource()).OnFlyCollection()]]>                    </defaultValueExpression>
</parameter>

And the Java Class

package beandatasource;

import java.util.ArrayList;

public class OnFlyCollection {

    public ArrayList<String> ListCollect() {

        ArrayList<String> arr_list = new ArrayList<String>();
        arr_list.add("A");
        arr_list.add("B");
        arr_list.add("C");

        return arr_list;
    }
}
