算法实现,请大家帮忙实现

Question

List> allList = new List>{
new List{"a","b","c"},
new List{"1","2","3"},
new List{"A","B","C","D","E"},
};

                    最后输出结果：a1A,a1B...c3E...

Answer 1

三层for循环

 for(String x:allList.get(0){
     for(String y:allList.get(1){
              for(String z:allList.get(2){
                       System.out.println(System.out.println(x + y + z);
                        }
            }
}
