Thread: read double from a file

I have created a "Savings Account" so to speak and I need to be able to read the balance from a file I have called balance.txt The file is formatted like this

******************************
 Tue Jun 04 23:59:51 CDT 2013
******************************
 Balance: $999.99
******************************

How do I get it to read only the numbers after "Balance: $"?

I am trying to do:

Scanner s = new Scanner("path to file");
    if (s.hasNextDouble){
        double balance = s.nextDouble();
    }

but it breaks the section of code where I write to the file.

public void toFile() throws IOException{
 String stars = "******************************";
 String content = stars + "\n " + date.toString() + "\n" + stars + "\n Balance: $" + balance + "\n" + stars;
  File file = new File("path to file");
  FileWriter fw = new FileWriter(file.getAbsoluteFile());
  BufferedWriter bw = new BufferedWriter(fw);
  bw.write(content);
  bw.close();
}

Eclipse puts a red line under void and throws. If I take away the ; from the scanner declaration, writing to file is fixed but the if statement and the scanner declaration are borked.

Scanner s = new Scanner("path to file");
    if (s.hasNextDouble){
        double balance = s.nextDouble();
    }

What is the value of balance after this code runs? Verify it with a println or debugger. What exactly do you do with this value besides read it in this snippet?
"but it breaks the section of code" This does not really explain what problem you have.
Post a SSCCE or explain what is going on and what you are stuck on. (or both)

The compiler problem sounds like it could be mismatched braces. But that's only a guess without seeing the code.
