java中list集合中交集的应用

常常用到要求两个集合的交集，即list.retainAll()方法的应用

public class GoddessAction {public static void main(String[] args) {String[] abc = new String[] { "abc", "acd", "add" };String[] abd = new String[] {"acd", "cd", "de"};List<String> abcList = new ArrayList<String>(Arrays.asList(abc));List<String> abdList = new ArrayList<String>(Arrays.asList(abd));abcList.retainAll(abdList);System.out.println("++++++++++++++"+abdList);}} 

倒入包全是java类型
