如何在Java中拆分字符串我的空行

Question

can anyone help me how to split string by empty lines? 谁能帮我如何用空行分割字符串？ for example i have following string 例如我有以下字符串

122 saf fsaf

sfa fasf

afsf

i want to split above string by empty lines and output should be as follows 我想用空行在字符串上方分割，输出应如下

string[0] = "abc def ghk
    122 saf fsaf"
String[1]="sfa fasf"
String[2]="afsf"

You can split the string on a newline that has only whitespace until the next newline: 您可以在只有空格的换行符上分割字符串，直到下一个换行符为止：

String input = "abc def ghk\n122 saf fsaf\n\nsfa fasf afsf";
String[] split = input.split("\n\\s*\n");
System.out.println(split[0]);
