问题描述
我试图在线搜索以解决这个问题,但我没有找到任何东西.
I tried to search online to solve this question but I didn't found anything.
我写了以下抽象代码来解释我在问什么:
I wrote the following abstract code to explain what I'm asking:
String text = "how are you?"; String[] textArray= text.splitByNumber(4); //this method is what I'm asking textArray[0]; //it contains "how " textArray[1]; //it contains "are " textArray[2]; //it contains "you?"
splitByNumber 方法将字符串text"每 4 个字符拆分一次.我怎样才能创建这个方法??
The method splitByNumber splits the string "text" every 4 characters. How I can create this method??
非常感谢
推荐答案
我认为他想要的是将一个字符串拆分为大小为 4 的子字符串.然后我会在循环中这样做:
I think that what he wants is to have a string split into substrings of size 4. Then I would do this in a loop:
List<String> strings = new ArrayList<String>(); int index = 0; while (index < text.length()) { strings.add(text.substring(index, Math.min(index + 4,text.length()))); index += 4; }
