Split a string in java and map to value with another string

Question

i need to split a string in java and map it to city ,country and continent

String s = "mumbai| india - Asia";
String b ="{city}|{country}-{Continent}"

where: | and - are special characters

output:

city - mumbai
country - india
continent - Asia

Is there a space between | and india, or is this a typo? — willeM_ Van Onsem

yes there can be space. My Logic is this<br> 1) using regex get a separator<br> 2) extract the text from string s 3) using regex get mapping from b and the produce the output — amit

Should be straightforward using one regex with three capture groups. — ajb

@user3205867 why you do not use replace? "| " ---> "|" and " - " --->"-" — Jens

why dont you use named capturing groups ?

(?<city>[^|]*)\s*\|\s*(?<country>[^-]*)-\s*(?<continent>[\w\s]*)

You Can try

String s = "mumbai| india - Asia";
String[] splitString = s.split("|");
String city = spiltString[0];
String secondSplit[] = splitString[1].split(" - ");
String country = secondSplit[0];
String continent = secondSplit[1];

 Try this.

 String s = "mumbai| india - Asia";
 String b ="{city}|{country}-{Continent}";

 String city = s.split("\\|")[0];
 String country = s.split("\\|")[1].split("-")[0];
 String cont =s.split("\\|")[1].split("-")[1];


 String cityT = b.split("\\|")[0];
 String countryT = b.split("\\|")[1].split("-")[0];
 String contT =b.split("\\|")[1].split("-")[1];



System.out.println(cityT.replace("{", "").replace("}", "") +" - " + city); 
System.out.println(countryT.replace("{", "").replace("}", "") +" - " +  country); 
System.out.println(contT.replace("{", "").replace("}", "") +" - " + cont);
