    Please do not post the same question twice in the forums. Your other post has been removed.

    For reading files, see Lesson: Basic I/O (The Java™ Tutorials > Essential Classes)

    For using arrays, sett Arrays (The Java™ Tutorials > Learning the Java Language > Language Basics)

    If you have more specific questions I'd recommend posting a bit of code to help demonstrate the problem.

    All the code you need can be found here in our Code Snippets forum - Java Code Snippets and Tutorials - Java Programming Forums

    Here is the code for reading a file line by line..

    import java.io.BufferedReader;
    import java.io.FileInputStream;
    import java.io.InputStreamReader;
     
    public class Class1 {
     
    public static void main(String[] args) {
     
      try
      {
      FileInputStream in = new FileInputStream("inputFile.txt");
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      String strLine;
     
      while((strLine = br.readLine())!= null)
      {
       System.out.println(strLine);
      }
     
      }catch(Exception e){
       System.out.println(e);
      }
     
     }
    }

    This part of the code prints the current line to the console. You need to add your array code here.

     System.out.println(strLine);

    See how far you can get and then post back when you get stuck.
