Java - Split and trim in one shot

Question

I have a String like this : String attributes = \" foo boo, faa baa, fii bii,\" I want to get a result like this :

String[] result = {\"foo boo\         


        

Answer 1

What about spliting with comma and space:

String result[] = attributes.split(",\\s");

Answer 2

Using java 8 you can do it like this in one line

String[] result = Arrays.stream(attributes.split(",")).map(String::trim).toArray(String[]::new);

Answer 3

If there is no text between the commas, the following expression will not create empty elements:

String result[] = attributes.trim().split("\\s*,+\\s*,*\\s*");

Answer 4

create your own custom function

private static String[] split_and_trim_in_one_shot(String string){
 String[] result  = string.split(",");
 int array_length = result.length;

 for(int i =0; i < array_length ; i++){
  result[i]=result[i].trim();
 }
 return result;

Overload with a consideration for custom delimiter

private static String[] split_and_trim_in_one_shot(String string, String delimiter){
 String[] result  = string.split(delimiter);
 int array_length = result.length;

 for(int i =0; i < array_length ; i++){
  result[i]=result[i].trim();
 }
 return result;

Answer 5

Best way is:

value.split(",").map(function(x) {return x.trim()});

Answer 6

String result[] = attributes.trim().split("\\s*,[,\\s]*");
