判断一个数组中是否含有某个字符串

String[] aArray = new String[]{"111","222","333","444","555","666","777","888"};
String[] bArray = new String[]{"1","90","91","92","4","5","93","102","96","103","2"};
List<String> aList = Arrays.asList(aArray);
List<String> bList = Arrays.asList(bArray);

也可以这样写

List<String> aList = Arrays.asList("111","222","333","444","555","666","777","888");
List<String> bList = Arrays.asList("1","90","91","92","4","5","93","102","96","103","2");

aList.contains("111")
