I have a text file that reads as follows:
item1, description # brand1, brand2
item2, description # brand3
I have an array list of brands and another array lists of items.
My code reads and assigns everything until it gets to the "#" after the item description...
while(input.hasNextLine())
{
String line = input.nextLine();
String[] token = line.split("[,#]+");
item = token[0];
description = token[1];
brand = token[2];
}
How can I get it to properly read what's after the "#" ?? I should mention that an item can belong to 2 or more brands
首先用“#”分割处理结果,然后用“,”分割。
I believe what you're looking for is regular expressions (regex)
It allows you set up a pattern that defines how the data is structured like this:
"(?<item>.+),\s(?<description>.+)\s\#\s(?<brands>.+)"
(disclaimer: just a quick example written by hand, might not work correctly) And then apply the pattern to a string using a matcher.
I'd strongly suggest you read up on regex, or take a tutorial on it. It's super useful. check out: http://docs.oracle.com/javase/tutorial/essential/regex/intro.html
