查找多个整数内的字符串使用正则表达式 [英] Finding Multiple Integers Inside A String Using Regex
问题描述
我目前有低于这个code:
I currently have this code below:
Pattern intsOnly = Pattern.compile("\\d+");
Matcher matcher = intsOnly.matcher(o1.getIngredients());
matcher.find();
String inputInt = matcher.group();
目前是什么情况是使用正则表达式,它发现一个字符串中的第一个整数,它分开,这样我可以开展它的行动。我使用发现里面整数字符串有很多的整数,我想他们都分开。我该如何调整这个code,这样它也从字符串记录等整数,不只是第一个。
What currently happens is that using Regex, it finds the first integer inside a string and separates it so that I can carry out actions on it. The string that I am using to find integers inside of has many integers and I want them all separate. How can I tweak this code so that it also records the other integers from the string, not just the first one.
在此先感谢!
推荐答案
在您的贴code:
matcher.find();
String inputInt = matcher.group();
您是匹配整个字符串用一个电话找到。然后分配位数的第一个匹配你的字符串 inputInt
。因此,举例来说,如果你有以下字符串数据,你的回报将只有 1
。
You are matching the whole string with a single call to find. And then assigning the first match of digits to your String inputInt
. So for example, if you have the below string data, your return will only be 1
.
1 egg, 2 bacon rashers, 3 potatoes
您应该使用,而
循环来在你的比赛。
You should use a while
loop to loop over your matches.
Pattern intsOnly = Pattern.compile("\\d+");
Matcher matcher = intsOnly.matcher(o1.getIngredients());
while (matcher.find()) {
System.out.println(matcher.group());
}
