extract data column-wise from text file using Java

Question

I\'m working under Java and want to extract data according to column from a text file.
\"myfile.txt\" contents:

    ID     SALARY RANK  
    065    120         


        

Answer 1

   while((line = b.readLine()) != null) {
      String[] columns = line.split(" ");
      System.out.println("my first column : "+ columns[0] );
      System.out.println("my second column : "+ columns[1] );
      System.out.println("my third column : "+ columns[2] );
   }

Now instead of System.out.println, do whatever you want with your columns.

But I think your columns are separated by tabs so you might want to use split("\t") instead.
