java中字符串到字符串数组的转换 [英] string to string array conversion in java

问题描述

我有一个 string = "name";我想转换成字符串数组.我该怎么做?有没有内置的java函数?手动我可以做到，但我正在寻找一个 Java 内置函数.

I have a string = "name"; I want to convert into a string array. How do I do it? Is there any java built in function? Manually I can do it but I'm searching for a java built in function.

我想要一个数组，其中字符串的每个字符都是一个字符串.像 char 'n' 现在将是存储在数组中的字符串n".

I want an array where each character of the string will be a string. like char 'n' will be now string "n" stored in an array.

推荐答案

为了让你开始你的作业，String.split 在正则表达式上拆分字符串，这个表达式可能是一个空字符串:

To start you off on your assignment, String.split splits strings on a regular expression and this expression may be an empty string:

String[] ary = "abc".split("");

产生数组:

(java.lang.String[]) [, a, b, c]

摆脱空的第一个条目留给读者作为练习:-)

Getting rid of the empty 1st entry is left as an exercise for the reader :-)

注意:在 Java 8 中，不再包含空的第一个元素.

Note: In Java 8, the empty first element is no longer included.
