Example — Getting the Field Names of a Structure Array

Create an MWStructArray object with three fields and display the field names:

int[] sdims = {1, 2};

String[] sfields = {"f1", "f2", "f3"};

MWStructArray S = new MWStructArray(sdims, sfields);

String[] str = S.fieldNames();

System.out.print("The structure has the fields: ");

for (int i=0; i<S.numberOfFields(); i++)

System.out.print(" " + str[i]);

When run, the example displays this output:

The structure has the fields: f1 f2 f3
