Question

My problems is that I have to arrange, when searching for a customer, arrange the while loop to only examine every fourth line read.

This is the code I already have on this problem:

BufferedReader br = new BufferedReader(new FileReader("Customers.txt"));
String line;

while ((line = br.readLine()) != null)
{
    ...
}

br.close();

Does anybody know what needs to be at the place of “…”?

Thanks!

Just call br.readLine() 3 times at the end of the loop, discarding the output:

BufferedReader br = new BufferedReader(new FileReader("Customers.txt"));
String line;

while ((line = br.readLine()) != null)
{
    ...
    for(int i=0;i<3;i++){ br.readLine(); }
}

br.close();
