Reading int with prefix from a file
As long as the format for each line is consistent, you can readLine, then Integer.parseInt(text.substring(text.indexOf(":")+2));
so this is what I've already imported and written:
is this what u meant?
cause it's not working :c
or do I have to replace 'text' with 'Volume'?
I've tried that too, but there was still an Error..
import java.io.FileWriter;
import java.io.FileReader;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.FileNotFoundException;
import java.util.List;
import java.util.ArrayList;
import java.util.Arrays;
try
{
BufferedReader input = new BufferedReader(new FileReader("options.txt"));
volume = Integer.parseInt(input.readLine());
Integer.parseInt(text.substring(text.indexOf(":")+2));
input.close();
}
I meant something like this for lines 16 and 17:
String text = input.readLine();
volume = Integer.parseInt(text.substring(text.indexOf(": ")+2));You need to login to post a reply.
