List调用toString()方法后,去除两头的中括号实例

import org.apache.commons.lang.StringUtils;  public class Test {   public static void main(String[] args) {          List<String> list = new ArrayList<String>();     list.add("1");     list.add("2");     list.add("3");          System.out.println(list.toString());     System.out.println(StringUtils.strip(list.toString(),"[]"));   }  } 

[1, 2, 3] 1, 2, 3
