Re: Objects and scope

Hello,

I am learning java and currently am working on a project that parses a
logfile line by line. I have a couple if statements that pull out
information important information and assigns the values to variables.
I would like to store these values in objects but when I create a new
instance of my object class in one of my if statements, I can only call
the methods from my class from inside that one if statemen and not from
others. I need to be able to update my object from all of the if
statements in the loop that is extracting the values.

here is my code.

try {
            BufferedReader br = new BufferedReader(new
FileReader("c:\\paul.txt"));
            Matcher
matcher1,matcher2,matcher3,matcher4,matcher5,matcher6;
            int toggle = 0;
            while ( (line = br.readLine()) != null ) {
                matcher1 =
Pattern.compile("^(\\d+:\\d+:\\d+)\\s(.*)\\sTrace:\\s\\[\\s+(\\d+)\\](.*):\\s.*\\(=\\sMessage\\sType\\s47\\);").matcher(line);
                matcher2 = Pattern.compile("^\\s+$").matcher(line);
                matcher3 =
Pattern.compile("^\\s(.*)\\s\\(\\=\\sSubtype\\s(\\d+)\\)\\;\\sDialogueID\\:\\s\\((.*)\\)\\s.*$").matcher(line);
                matcher4 =
Pattern.compile("^\\s{3}.*:.*").matcher(line);
                if (matcher1.find()) {
                    toggle = 1;
                    timeStamp = matcher1.group(1);
                    pim = matcher1.group(2);
                    traceID = matcher1.group(3);
                    ConvDir = matcher1.group(4);
                }
                if (matcher2.find()) {
                    toggle = 0;
                }
                if (toggle ==1) {
                    //extract mesage name, subtype, and dialog ID
                    if (matcher3.find()) {
                        messageName = matcher3.group(1);
                        subType = matcher3.group(2);
                        dialogueID = matcher3.group(3);
                        //System.out.println("Subtype:" + subType + "
DialogueID:" + dialogueID + " Name:" + messageName + " Time:" +
timeStamp + " PIM:" + pim + " TraceID:" + traceID + " Conv Dir:" +
ConvDir);
                    }

                    if (matcher4.find()) {
                        Matcher ani_matcher =
Pattern.compile("^\\s{3}ANI:(.*)").matcher(line);
                        if (ani_matcher.find()) {
                            //System.out.println("Found ANI: " +
ani_matcher.group(0));
                        }
                    }
                }
            }

        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

Thanks for taking the time to read this. I appreciate your help.
