java - 如何将字符串拆分为单词、空格和换行符？

Question

我正在使用 Play 框架并从文本区域获取文本，我想将其拆分为输入的单词、空格和换行符的数组。

Hello World How

Are You

会是这样的

a[0] = "Hello";
a[1] = " ";
a[2] = "World";
a[3] = " ";
a[4] = "How";
a[5] = "\n";
a[6] = "Are";
a[7] = " ";
a[8] = "You";

如果有一个简单的正则表达式方式或类似的东西我很想听听？

Answer 1

试试这个代码:

String str = "Hello World How\nAre You";
String[] inputs = str.split("(?!^)\\b");
for (int i=0; i<inputs.length; i++) {
   System.out.println("a[" + i + "] = \"" + inputs[i] + '"');
}

OUTPUT:
a[0] = "Hello"
a[1] = " "
a[2] = "World"
a[3] = " "
a[4] = "How"
a[5] = "
"
a[6] = "Are"
a[7] = " "
a[8] = "You"
