Question

I read the next answer about load file into java application.

I need to write a program that load .txt, which contains a list of records. After I parse it, I need to match the records (with conditions that I will check), and save the result to XML’s file.

I am stuck on this issue, and I will happy for answer to next questions:

1. How I load the .txt file into Java?
2. After I load the file, how I can acsses to the information into it? for example, How I can asked if the first line of one of the records is equal to “1”;
3. How I export the result to XML’s file.

Answer 1

one: you need a sample-code for reading a file line by line

two: the split-method of a string might be helpful. For instance getting the number of the first element if information is seperated by a space

String myLine;
String[] components = myLine.split(" ");
if(components != null && components.length >= 1) {
    int num = Integer.parseInt(components[0]);
    ....
}

three: you can just write it like any text-file, or use any XML-Writer you want
