如何将list集合转成String对象

使用Stringutils中的join方法:

方法一:

public String listToString(List list, char separator) {    
  return org.apache.commons.lang.StringUtils.join(list.toArray(),separator);   
}

方法二:

public String listToString(List list, char separator) {    
    StringBuilder sb = new StringBuilder();    
    for (int i = 0; i < list.size(); i++) {        
        if (i == list.size() - 1) {            
           sb.append(list.get(i));        
        } else {            
          sb.append(list.get(i));            
          sb.append(separator);        
        }   
     }    
  return sb.toString();}

方法三:

public String listToString(List list, char separator) {    
    StringBuilder sb = new StringBuilder();    
    for (int i = 0; i < list.size(); i++) {                
                 sb.append(list.get(i)).append(separator);    
           }    
            return sb.toString().substring(0,sb.toString().length()-1);
     }
