Question

How do I use java to read a simple offline html file?

Answer 1

How do you want to read it? I have some file I/O demos if you want to see them....

Answer 2

I want it to scan for a certain phrase with a number and output that number.

Answer 3

In Java you can connect an instance of Scanner to an instance of FileInputStream and pass in the file name or path. Then you can use the nextLine() method to grab a line of text as a String from your HTML file.
Example lines:
import java.util.* ;
import java.io.* ;
Scanner inputStream = new Scanner(new FileInputStream("HTMLfilename.html"));
while(inputStream.hasNextLine())
{
String theLine = inputStream.nextLine();
// do your checks to see if your string has the phrase you want here
}
inputStream.close();

I included an example File I/O program from one of my instructors below for you to run. Good luck.
