Skip Line/Pattern with Scanner class

[Viv Singh]

Hi,

I have the following content in a file:

Drives
********
cdr LITEON DVD-ROM LTD163 GDHA
cdr HL-DT-ST CD-RW GCE-8400B B104

My aim is to extract the information of both drives and I have written the following code:

   
while(s.hasNextLine()) {
	String line = s.nextLine();
			
	if(line.startsWith("Drives"))	{
		line = s.nextLine();
		line = s.nextLine(); // skip the pattern ******
		while(line.startsWith("cdr")) {
			tmp_drive = tmp_drive.concat(line.substring(4,line.length()));
			line = s.nextLine();
		}
         }
}

I use s.nextLine() to skip the pattern *******, I tried to use the built in method skip as follows:

s.skip("*******");

but that did not work. Am I doing something wrong?

thanks in advance.

* is part of regular expressions, so you will need to escape it with a \ (which again must be escaped because it is part of a string):

s.skip("\\*\\*\\*\\*\\*\\*\\*");

Of course, this can be shortened by using the count operator:

s.skip("\\*{7}");

See Pattern for more information on regular expressions.
