hi, is it possible to post a line using coordinates, forexample if i want to post a line at the following coordinates (5,6)
Like I remember in Turing you can do that

For example here is the following code which shows all the directories and files

code:
import java.io.*;
import java.util.*;
import java.text.*;
class Asn62
{
    public static void main (String [] args)
    {
       
        System.out.println ("\t\t\t\tDirectory\n");
            System.out.print ("Name");
            System.out.print ("\t                   Type");
            System.out.print ("\t\tLast Modified");
            System.out.println ("\t\t\tLength");
        String [] Directories;
        String [] Files;
        double [] Modified;
        double [] theLength;
        Files = new String [6] ;
        Directories = new String [6];
        Modified = new double [6];
        theLength = new double [6];
 
 
        File folder = new File ("F:/");
        File [] listOfFiles = folder.listFiles ();
 
        for (int i = 0 ; i < listOfFiles.length ; i++)
 
            {
                if (listOfFiles [i].isFile ())
                {
                    Files [0] = listOfFiles [i].getName ();
 
                                System.out.println (Files [0]);
                }
                else if (listOfFiles [i].isDirectory ())
                {
                    Directories [0] = listOfFiles [i].getName ();
                                System.out.print (Directories [0]);
                                System.out.println("      Dir");
                }
 
                long t = listOfFiles [i].lastModified ();
 
                Modified [0] = t;
 
                long s = listOfFiles [i].length ();
                theLength [0] = s;   
 
            }         
   
}
}


Here is the output

Post subject:  RE:Need help in printing a line
printf or String.format() or Formatter class, use the "indent" flag
eg.
code:
System.out.printf("%10s%n","hi");
System.out.printf("%10s%n","supahsain08");

k i replaced this
code:
System.out.println ("Dir");

with this
code:
System.out.printf("%25s%n","Dir");

but still the same output

code:
System.out.printf("%-25s%s%n","myHomeWork","dir");
System.out.printf("%-25s%s%n","games","dir");
the negative sign cause it to left(?) align text, and by default its right(?) aligned, so we change it and add the extra space we wanted

Here is the code
code:
import java.io.*;
import java.util.*;
import java.text.*;

class Asn62
{
    public static void main (String [] args)
    {
       
        System.out.println ("\t\t\t\tDirectory\n");
            System.out.print ("Name");
            System.out.print ("\t                      Type");
            System.out.print ("\tLast Modified");
            System.out.println ("\t\t\tLength");
            System.out.println ("");
        String [] Directories;
        String [] Files;
        double [] Modified;
        double [] theLength;
        Files = new String [6] ;
        Directories = new String [6];
        Modified = new double [6];
        theLength = new double [6];


        File folder = new File ("F:/");
        File [] listOfFiles = folder.listFiles ();

        for (int i = 0 ; i < listOfFiles.length ; i++)

            {
                if (listOfFiles [i].isFile ())
                {
                    Files [0] = listOfFiles [i].getName ();

                                System.out.printf("%-30s%s%n",Files [0],"File");;
                }
                else if (listOfFiles [i].isDirectory ())
                {
                Directories [0] = listOfFiles [i].getName ();
               
               
                System.out.printf("%-30s%s%n",Directories [0],"Dir");
               
               
                               
                               
                }

                long t = listOfFiles [i].lastModified ();

                Modified [0] = t;
                                System.out.println ("\t\t\t\t\t" + Modified [0]);
                long s = listOfFiles [i].length ();
                theLength [0] = s;
         

            }
 
}
}


EDIT: how will i add another another thing in this code, forexample if i want to add another word like "hi" after 35s?
code:
System.out.printf("%-30s%s%n",Files [0],"File");;

welcome Smile
now, i have a question for you
code:
                double [] Modified;               
Modified = new double [6];
                long t = listOfFiles [i].lastModified ();
                Modified [0] = t;
modified is an array of double, length of 6, ok, and now you are only making use of the first element, what's up with that? (unless i missed some part of course Confused)

and now you have
code:

            System.out.println ("\t\t\t\t\t" + Modified [0]);
why cant you just do the same with the dir and file name?

and sorry i dont get your last question, what do you mean by, add hi after 35s? after 35 seconds? what is s Smile

i think i figured it out

code:
import java.io.*;
import java.util.*;
import java.text.*;

class Asn62
{
    public static void main (String [] args)
    {

        System.out.println ("\t\t\t\tDirectory\n");
        System.out.print ("Name");
        System.out.print ("\t                  Type");
        System.out.print ("\tLast Modified");
        System.out.println ("\t\t       Length (bytes)");
        System.out.println ("");
        String [] Directories;
        String [] Files;
        double [] Modified;
        double [] theLength;
        Files = new String [6];
        Directories = new String [6];
        Modified = new double [6];
        theLength = new double [6];


        File folder = new File ("F:/");
        File [] listOfFiles = folder.listFiles ();

        for (int i = 0 ; i < listOfFiles.length ; i++)

            {

                long t = listOfFiles [i].lastModified ();

                Modified [0] = t;

                long s = listOfFiles [i].length ();
                theLength [0] = s;


                if (listOfFiles [i].isFile ())
                {
                    Files [0] = listOfFiles [i].getName ();

                    System.out.printf ("%-26s%s%-3s%s%-3s%s%n", Files [0], "FIL", "", new Date (t), "", theLength [0]);
                }
                else if (listOfFiles [i].isDirectory ())
                {
                    Directories [0] = listOfFiles [i].getName ();

                    System.out.printf ("%-26s%s%-3s%s%-3s%s%n", Directories [0], "DIR", "", new Date (t), "", theLength [0]);

                }

            }

    }
}
