how can i ignore white space while scanning

Question

I have a file:

12345678;ABC 123456A12345678;45678945

This is what I do:

Scanner s = new Scanner(new File(testCase.getFileName()));
while (s.hasNext()) {
    String[] lineItems = s.next().split(";");
}

Output:

12345678;ABC
123456A12345678;
45678945

Desired output:

12345678
ABC 123456A12345678
45678945

I want it to consider "ABC 123456A12345678" as one single token and not break when it encounters whitespace.

What should I do?

Solution

From here:

"A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace".

So, your program splits the file according to whitespace first, and then .split(";"); splits these by ;.

You need to set the delimiter to ; as follows:

Scanner s = new Scanner(new File(testCase.getFileName())));
s.useDelimiter(";");
while (s.hasNext()) {
   System.out.println(s.next());
}
