Java: Getting a substring from a string starting after a particular String

Question

I have a string:

CLAIM NUMBER 1234563 AND INCIDENT DATE 12/12/2020 12:00:00 

I would like to extract 1234563 and 12/12/2020 12:00:00 from this, i.e. the substring after the NUMBER and DATE.

Could someone please provide some help?

I tried though the the substring and index but it's not giving expected answer.

It is better to use regexp to extract data from formatted string.

final String regex = "CLAIM NUMBER\\s+(?<claimNumber>\\S+)\\s+AND INCIDENT DATE\\s+(?<incidentDate>\\S+\\s+\\S+)";
final String str = "CLAIM NUMBER 1234563 AND INCIDENT DATE 12/12/2020 12:00:00";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(str);

if(matcher.matches()) {
    String claimNumber = matcher.group("claimNumber");
    String incidentDate = matcher.group("incidentDate");
}
