去掉全角空格和半角空格

1 String value = "　　俞子东 ";
2         char[] val = new char[value.length()];
3         value.getChars(0, value.length(), val, 0);//字符串转换成字符数组
4 
5         System.out.println(val.length)

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

 1 static String myTrim(String source, String toTrim) {//将字符串两边的半角空格、全角空格去掉，其他也可以
 2         StringBuffer sb = new StringBuffer(source);
 3         while (toTrim.indexOf(new Character(sb.charAt(0)).toString()) != -1) {
 4             sb.deleteCharAt(0);
 5         }
 6         while (toTrim.indexOf(new Character(sb.charAt(sb.length() - 1))
 7                 .toString()) != -1) {
 8             sb.deleteCharAt(sb.length() - 1);
 9         }
10         return sb.toString();
11     }
