How to read a file, then select a line and use what comes after the selected characters.

[matthew christensen]

So I'm writing a simple event logging program for my game. But I have a problem. I have a .properties file. That contains 3 lines of text(lines of text below)

max-file-size=15
log-path=C:\LWLW\
log-file-name=LWLog.txt

I want to scan the file, then somehow use the data darkened below to set the path, max file size, and the save path.

max-file-size=15
log-path=C:\LWLW\
log-file-name=LWLog.txt


How would I go about doing this? I tried google for answers but alas nothing came of my search. Thanks guys!

If you were going to describe the bolded part in English, how would you do that?

No, actually you said you have a .properties file. So you don't have to parse it yourself (which is what I was mistakenly getting at in my previous post). Just create a Properties object to read that file and extract the properties from it. (You'll have to format it correctly, though, I think the backslash has a special meaning in a .properties file, check that out.)

What do you mean by a properties object?

Here's the code if anyone is interested!

package config;

import java.io.FileInputStream;
import java.util.Properties;

public class LWLWConfigurationReader {

    public String logPath;
    public String fileName;
    public String maxFileSize;
    public String timeStamp;
    
    public void readConfigurationFile() {
        Properties logPropeties = new Properties();
        
        try {
            logPropeties.load(new FileInputStream("\\LWLW\\LWLW.properties"));
            maxFileSize = logPropeties.getProperty("max.file.size");
            logPath = logPropeties.getProperty("log.path");
            fileName = logPropeties.getProperty("file.name");
            timeStamp = logPropeties.getProperty("time.stamp");
            
        } catch (Exception e) {
            System.out.printf("Error: %s", e.getMessage());
        }
    }
}

Thank you for showing us that.
