字符串数组转换为list集合
2022-06-24 21:53:00 【全栈程序员站长】
大家好,又见面了,我是你们的朋友全栈君。
String[] arr = {"a", "C", "abc"};
// asList 该方法可以直接将一个数组转换为list集合,但是该集合是 [只读的],不能对得到的集合进行增删改
List<String> asList = Arrays.asList(arr);
System.out.println(asList); // 结果:[a, C, abc]
List list = new ArrayList(asList);//经此步可以实现增删改
list.add("ddd");
System.out.println(list);//结果为[a,b,ccc,ddd]发布者:全栈程序员栈长,转载请注明出处:https://javaforall.cn/151785.html原文链接:https://javaforall.cn
