Writing data to text file in table format

Question

So far I have this:

File dir = new File(\"C:\\\\Users\\\\User\\\\Desktop\\\\dir\\\\dir1\\\\dir2);
dir.mkdirs();
File file = new File(dir, \"filename.txt\");
         


        

Answer 1

The \r\n is been evaluated as part of the second parameter, so it basically calculating the required space as something like... 20 - "column 2".length() - " \r\n".length(), but since the second line doesn't have this, it takes less space and looks misaligned...

Try adding the \r\n as part of the base format instead, for example...

String.format("%20s %20s \r\n", "column 1", "column 2")

This generates something like...

        column 1             column 2
          data 1               data 2

In my tests...
