Question

I am trying to check if a range of numbers exist in a string
Any more elegant way than this?

if (ccnumeric.contains("51")
    || ccnumeric.contains("52")
    || ccnumeric.contains("53")
    || ccnumeric.contains("54")
    || ccnumeric.contains("55"))

I can’t think of any method that satisfies this as I am checking for an int range in a string.

You could use a simple regex: 5[12345]{1} to look for a 5 followed by exactly one 1,2,3,4 or 5:

String s = "55";
Pattern p = Pattern.compile("5[12345]{1}");
if (p.matcher(s).find()) {
    System.out.println("Found");
} else {
    System.out.println("Not Found");
}
