Java-将字符串拆分为数组

Question

I have this code

String speed_string = "baka baka saka laka";
String[] string_array = speed_string.split(" ");
System.out.println(string_array.length);

and it returns the value of 1 when I run it. Why is that? It seems as if only the first word of the string gets saved.

Answer 1

Use \\\\s and update the code as below

       String speed_string = "baka baka saka laka";
       String[] string_array = speed_string.split("\\s");
       System.out.println(string_array.length);

Answer 2

Most probably what you think is space (ASCII decimal 32) is not (in your input string).
That would explain perfectly the behavior you're seeing.
