Can find variable

Question

Hi, I'm having a problem of using a variable I declared in another class
How can I call this variable in my main method??
THX
CODE:
public class ppage{
static General general;
public static void main (String args[])
general = new General();
System.out.printl(general.ppage_dir);--> he doesn't know this parameter
public class General extends Object
static String ppage_dir;
static String log_dir;
public void readConfigFile()
try
File inputFile = new File("/Java/log/config.sys");
BufferedReader input = new BufferedReader(new FileReader(inputFile));
String temp;
temp=input.readLine();
while (temp!=null)
if (temp.indexOf("PPAGE_DIR=")!=-1)
ppage_dir=temp.substring(10);
else if
log_dir=temp.substring(8);
temp=input.readLine();
input.close();
catch (IOException exp)
System.out.println("Fatal error, can't read from file - "+exp.getMessage());
}

Answer 1

Create a method that will return the value of ppage_dir.
public static String getPageDir()
return ppage_dir;
// Insert the above code into the General class
Just to let you know, your program is probably not working because you didn't declare a value for ppage_dir. Either that or you meant to run readConfigFile() before you retrieved the value of ppage_dir.
A simple way to do this would be to use a Properties file and retrieve the values directly. This way, you avoid the need to worry about "indexOf("PPAGE_DIR=")"
