> Have a do..while loop that loops until the user enters a blank line. Have an integer variable that counts the number of lines. Here is an example:
>


> System.out.println("Enter the lines of text. Enter an empty line to end.");
> int numLines = 0;
> do {
>   line=SavitchIn.readLine();
>   if (!(line.equals("")) {
>     numLines++;
>   }
> } while (!(line.equals(""));

> Also, if you wanted to keep the user input, everytime you call the readLine method, add the result of that method to the end of the variable line (assuming line is a string), like so:
>


> line = line + SavitchIn.readLine();
> // I think line =+ SavitchIn.readLine(); will work as well, but
> // I'm not entirely sure
