java：如何在空格和大寫字母之間分割字符串？

Question

舉一個例子："Today's food will be fish Tomorrow's food will be soup"

我想包含

{Today's food will be fish,Tomorrow's food will be soup} 

我怎樣才能做到這一點的字符串數組？

Answer 1

您可以使用拆分與此正則表達式(?=\s[A-Z])例如：

String str = "Today's food will be fish Tomorrow's food will be soup"; 
System.out.println(Arrays.toString(str.split("(?=\\s[A-Z])"))); 

輸出

[Today's food will be fish, Tomorrow's food will be soup] 

Answer 2

試試這個

String a="Today's food will be fish Tomorrow's food will be soup"; 
String[] b = a.split("\\s(?=[A-Z])"); 

和b是：今天的食品將是魚，明天的食物將是湯]

Answer 3

爲了支持國際字符，我建議使用以下表達式，建立在YCF_L上：答案。

String str = "Today's food will be fish Tomorrow's food will be soup"; 
System.out.println(Arrays.toString(str.split("(?=\\s\\p{Lu})")));
