This article is about how java converts an array of strings into comma-separated strings. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

It usually goes like this:

Public static void main (String [] args) {String strs = ""; String [] arr = new String [] {"aa", "cc", "bb"}; / / string array before conversion StringBuilder sb = new StringBuilder (); for (String ele: arr) {if (sb.length () > 0) {sb.append (",");} sb.append (ele) } strs = sb.toString (); / / comma-delimited string System.out.println (strs);}

A simpler way to write:

Public static void main (String [] args) {String [] arr = new String [] {"aa", "cc", "bb"}; / / pre-converted string array String strs = String.join (",", arr); / / comma-separated string System.out.println (strs) after conversion;} Thank you for reading!
