Yes, this will make the example correct.
This sample code demonstrates what is discussed in the docs:
MaskFormatter formatter = new MaskFormatter("###-####");
formatter.setPlaceholderCharacter('_');
System.out.println(formatter.valueToString("123"));
formatter = new MaskFormatter("###-####");
formatter.setPlaceholderCharacter('*');
formatter.setPlaceholder("555-1212");
System.out.println(formatter.valueToString("123"));
and produces the output:
123-____
123-1212
which perfectly aligns with the documentation.
