How to tick iTextPdf?

Question

How to set a checkbox in iText?

form.setField("pt_gender_female", "On");
form.setField("pt_gender_female", true);

I made a couple of trial and error, but none of them worked. I searched, but did not find the perfect answer.

Answer 1

String states[] = stamper.getAcroFields().getAppearanceStates("pt_gender_female");
form.setField("pt_gender_female",states[1]);

I tried snipet cloister. He checked the box.

Answer 2

This is how it is done in itextPdf

form.setField("pt_gender_female","Yes"); // to check it
form.setField("pt_gender_female","Off"); // to uncheck it
