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
