This code just reads the first line. You want to keep reading until you get to different line, right?

Inside your while loop you will want to something like this:

if(isThisSecondLine()){

break;

}

if(hasFirstLineOccurred()){

doSomethingWithThisLine();

}

BufferedReader in = new BufferedReader(new FileReader("Results.log"));

while((str=in.readLine())!=null){

if(str.startsWith("APDU")){

if(str.startsWith("Time"))

break;

else

System.out.println(str);

}

}

I have given the above statements to print the information between two non-consecutive lines. But it's not working.

Can any one suggest me a way to do this.

boolean logging = false;

while((str=in.readLine())!=null){

if(str.startsWith("APDU")){

logging = true;

list.add(str);

System.out.println(str);

}

else if(logging) {

list.add(str);

System.out.println(str);

if(str.startsWith("END"))

logging=false;

}

}

You'll, of course, need to replace END with whatever you're looking for to end the log. And if you want to end the while loop immediately after it reads the END part, just change that statement to:

if(str.startsWith("END")) {

logging = false;

break;

}
