根据定界符分割字符串

Question

通过截止日期将一个字符串作为输入，其形式为23、4、555、67，另一个输入是关键，您可以线性搜索元素吗？我的问题是如何从字符串中用逗号分隔来识别元素

Answer 1

您可以使用split拆分String：

String[] tokens = "23,4,555,67".split(",");

Answer 2

String s = "23,4,555,67"
String[] tokens = s.split(",");

This will give you a string array with the numbers.

Answer 3

Alternatively, you can use a StringTokenizer. (java.util)

This can be used if your string is delimited by more than one characters (can be be used as well in case of single character). Your example using StringTokenizer

SrringTokenizer st = new StringTokenizer("23,4,555,67", ",");
while(st.hasMoreElements())
    System.out.println(st.nextToken());
