You can use the following RegEx, \\d{6,10}. This would match any string which has only digits and the number of times digits can occur is 6 to 10.

(By digit we mean any character with the Unicode General Category of Nd (Number, Decimal Digit.) as Java uses the ICU Regular Expressions libraries.)

You can see how the RegEx works here

    String pattern = "\\d{6,10}", myString = "111111";
    System.out.println(myString.matches(pattern));

would print

true
