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); }

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() +" "); }

You can try something like this: String str = "New York 60 50 40 30"; str = str.replaceAll("[A-Za-z]", ""); System.out.println(str); Read more about regular expressions: https://www.vogella.com/tutorials/JavaRegularExpressions/article.html

import java.util.regex.Matcher; import java.util.regex.Pattern; ... Pattern pattern = Pattern.compile("\\d.+\\d"); Matcher matcher = pattern.matcher("New York 60 50 40 30"); String part = matcher.find() ? matcher.group() : ""; System.out.println( part );

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.

replaceAll method gives some spaces before integers it looks like : 60 50 40 30. Need no spaces before line.

Here is the solution replaceAll("\\p{L}+\\s","")

String s = "New York 60 50 40 30"; for(String t: s.split(" ")){ if(t.matches(".*\\d.*")){ System.out.println(t); } } // this way works as well if you want like this

I know that it will be String.split, but how exactly?
