Como usar mascara netbeans

Boa noite!!!
como que eu faço para criar uma mascara com JTextFormattedField no netbeans?

tentei dessa forma:Cliquei em cima do JTextFormattedField e depois em propriedades.
Na aba: CODE vai ate o: Custom Create Code

new javax.swing.JFormattedTextField(); 
MaskFormatter MASK_CPF = null; 
try{ 
   MASK_CPF = new MaskFormatter("#########-##"); 
}catch (Exception e){ 
   e.printStackTrace(); 
} 
jFTF_CPF = new javax.swing.JFormattedTextField(MASK_CPF);

So que esta dando essa mensagem de erro
