我正在编写代码,我需要将一个字符串拆分为3个不同的部分,每个部分都需要自己的分隔符来获取单个部分.我对正则表达式并不擅长,我看过的教程并没有真正解释这一点.所以,如果你能把我推向正确的方向,如果你有答案解释它的每一部分都会很棒!

我的意见是

1 imported bottle of perfume at 27.99
1 bottle of perfume at 18.99
1 packet of headache pills at 9.75
1 box of imported chocolates at 11.25

我想要的输出是每个输出3个字符串.

"1" "imported bottle of perfume" "27.99"

码:

String pattern = "[(\\d)][(\\w)][(\\d)]";
String[] splits = data[i].split(pattern);
