Here's another solution similar to Denise Roßberg's👍🍻

String s = "New York 60 50 40 30";

String filtered = s.replaceAll("[^0-9]", " ");
String[] numbers = filtered.split("\\s+");

for (String n : numbers) {
System.out.println(n);
}

Answer 3

Ilja Veselov Here is, with No space before integers:

import java.util.regex.Pattern;
import java.util.regex.Matcher;

String s = "New York 60 50 40 30";

Pattern pattern = Pattern.compile("\\d+");
Matcher match = pattern.matcher(s);

while (match.find()) {
System.out.print(match.group() +" ");
}

Answer 8

Unfortunately this is not an answer to my question. Program is reading strings from a fila and I can't count chartAt index every time as all strings have different lengths . I have common pattern for all strings first location and then numbers so I need to split all strings to only numbes.
