Question

For processing a searchlog file I’m writing a Java class that should read and handle the file content line by line.

The Text in the Logfile looks like the following

[Integer User ID] [Queury] [Date: YYYY-MM-DD HH:MM:SS] [optional url]

I tried using a scanner and reading the lines with nextLine(), but this reads the whole file as one line. Any idea how I can ensure to only get one line at a time?

You can just grab the entire file as you have it, and then split the data:

for ( String line : "the entire file".split( System.getProperty("line.separator") )
{
     System.out.println( line );
}

As a side note: System.getProperty("line.separator") is the universal new line character.

An alternative method:

BufferedReader bufferedReader = new BufferedReader( new FileReader( "absolute file path" ) );

String line;

while ( ( line = bufferedReader.readLine() ) != null)
{
     System.out.println( line );
}
