How can I set limits on how many characters can be inputted? (Java) -

do{         out.println("\n---------------------------------");         out.println("---------------------------------");         out.print("please type acces card number: ");      try{         card = input.nextint();          if(card.length != 10){             out.println("the number typed incorrect");             out.println("the number must 10 numbers long");         continue;             }         }             catch(inputmismatchexception ex){             }     }while(true);     

im trying make card 10 characters long. (1234567890), , if user inputs (123) or (123456789098723) error message should appear. card.length doesnt seem work.

just change int string

   string card = input.next();    if(card.length() != 10){       //do    } 

you can convert int later

   int value = integer.parseint(card);
