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); }
