Multiple delimiters in Scanner class of Java

Question

How do I use the useDelimiter() method of the Scanner class to use both the comma (,) and the new line character (\n) as delimiters?

I am parsing some text from a csv file.

Answer 1

 Scanner s = new Scanner("hello, world \n hello world");
 s.useDelimiter(",|\\n");
 while(s.hasNext()){
          System.out.println(s.next());

 }

Output

hello
 world 
 hello world

Answer 2

How about useDelimiter(",|\\n");

Answer 3

useDelimiter takes a regex pattern, so, it would be something like ",|\n"

Answer 4

Jigar is absolutely correct. But if it doesn't work, try ",|\\r"

since most text files have \r\n instead of just \n

Answer 5

Using Scan Delimiters for Excel files - don't overlook the RegEx thing. In my case the excel file is delimitedby '|'. I have been spending significant time to parse rows using scanner.useDelimiter("|"), and got back character by character. Replacing that with scanner.useDelimiter("\\|") has solved my issue!
