Example — Getting the Number of Fields in a Structure Array
Create an MWStructArray object with three fields and display the number
of fields:
int[] sdims = {1, 2};
String[] sfields = {"f1", "f2", "f3"};
MWStructArray S = new MWStructArray(sdims, sfields);
String[] str = S.fieldNames();
System.out.println("There are " + S.numberOfFields() +
" fields in this structure.");
When run, the example displays this output:
There are 3 fields in this structure.
