Yeah, I've checked with `valueToString` method, its working fine. I'll replace
`getDisplayValue` with `valueToString`? ValueToString takes one parameter which
is of Object type. It return the formated value.
Sample Code:
MaskFormatter formatter = new MaskFormatter("###-##");
formatter.setPlaceholderCharacter('*');
System.out.println(formatter.valueToString("87"));
Output:
87*-**
