如何让在一行中输入逗号分隔的数字到Java中的数组 [英] how to get numbers separated by comma entered in a line into an array in Java

问题描述

我怎么能得到用户EQ的一行中输入值：1，3，400，444，等到一个数组。我知道我必须在此情况下，宣布一个分隔逗号，。可能有人帮助

感谢

解决方案

 字符串输入=1，3，400，444;
的String []号= input.split（\\\\ S *，\\\\ S *）;
 

您可以用更简单的分隔符<一个href=\"http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split%28java.lang.String%29\"><$c$c>String.split()像，，但更复杂的\\\\ S *，\\\\ S *另外去掉逗号周围的空格

how could I get values entered in a single line by the user eq: 1, 3, 400, 444, etc.. into an array. I know I must declare a separator in this case the comma ",". Could someone help

Thanks

解决方案

String input = "1, 3, 400, 444";
String[] numbers = input.split("\\s*,\\s*");

You can use much simpler separator in String.split() like "," but the more complex "\\s*,\\s*" additionally strips whitespaces around comma.
