如何把一段逗号分割的字符串转换成一个数组?
这个也是面试题,相信大家有好的回答?

String s = "a,b,c,d,e";
String[] arr = s.split(",")

String s = "a,b,c,d,e";
String[] arr = s.split(",")

  String ss = "a,b"; String[] arr = ss.split(",")；

split分割

String s = "a,b,c,d,e,f,g";
String[] arr = s.split(",")

String s = "a,b,c,d,e,f,g";
String[] arr = s.split(",")

String的split()方法

正则表达式分割成多个字符串，字符串数组存储就行了

String s = "a,b,c,d,e"; String[] arr = s.split(",")字符串数组存储嘿嘿,恭喜大家,看来都很厉害!
