Remove fullwidth and halfwidth Spaces

Requirement 1: convert a string to a character array

String value = "Yu zidong" [] val = value. getChars (0, value. length (), val, 0); System. out. println (val. length)

Requirement 2: Remove all fullwidth and halfwidth Spaces

 System.out.println(value.replaceAll("　| ", ""));

Requirement 3: remove the halfwidth and fullwidth spaces on both sides of the string (call myTrim (value ,"");)

  String myTrim(String source, String toTrim) {         StringBuffer sb =           (toTrim.indexOf( Character(sb.charAt(0)).toString()) != -1             sb.deleteCharAt(0           (toTrim.indexOf( Character(sb.charAt(sb.length() - 1                 .toString()) != -1             sb.deleteCharAt(sb.length() - 1               }

Complete code:

String value = "Yu zidong" [] val = value. getChars (0, value. length (), val, 0); System. out. println (value. replaceAll ("|", "" System. out. println (myTrim (value, "" String myTrim (String source, String toTrim) {StringBuffer sb = (toTrim. indexOf (Character (sb. charAt (0 )). toString ())! =-1 sb. deleteCharAt (0 (toTrim. indexOf (Character (sb. charAt (sb. length ()-1. toString ())! =-1 sb. deleteCharAt (sb. length ()-1}
