[Java] 判断一个list是否包含于另一个list，如果没有，输出没包含的

ArrayList<String> actualList = ["1","2","3"]
ArrayList<String> expectList = ["1","5","6"]
containsList(actualList, expectList )

//Check the expectList in actualList
static def containsList(ArrayList<String> actualList, ArrayList<String> expectList){
    if(actualList.containsAll(expectList)){
            assert true
    }  else {
        ArrayList<String> actualListBackUp = actualList.clone()    
        expectList.removeAll(actualList)
        assert false, "This data is not in list  " + expectList
    }
}

ArrayList<String> liasA = Arrays.asList(list);
