but i get this :

===================================================================================================

       Section 1              Section 2           Section 3
--------------------------------------------------------------------------------------------------
1110 - Ahmed Sami - Active 1116 - Maher Alsolami - Active 
1111 - Mohammed Turkey - Active 1117 - Mohanned Sami - Active 
1112 - Sami Omer - Active 1118 - Feras Ahmed - Active

here is the code i use (the code does give an error in the end i just want to know how can sorted like the first table):

System.out.println("\nThe first distribution for students among the available sectios ");
System.out.println("===================================================================================================\n"
    + "\n"
    + "       Section 1           Section 2           Section 3\n"
    + "--------------------------------------------------------------------------------------------------");
for (int i = 0; i < 6; i++) {
   System.out.printf("%s%s%s%s", students[i].getStudID() + " - ", students[i].getFname() + " ", students[i].getLname() + " - ", students[i].getStatus() + " ");
   System.out.printf("%s%s%s%s", students[i + 6].getStudID() + " - ", students[i + 6].getFname() + " ", students[i + 6].getLname() + " - ", students[i + 6].getStatus() + " ");
   System.out.printf("%s%s%s%s", students[i + 12].getStudID() + " - ", students[i + 12].getFname() + " ", students[i + 12].getLname() + " - ", students[i + 12].getStatus() + " ");
   System.out.println("");
}

Instead of %s%s%s%s, use sufficient space for individual parts e.g. in the following statement, %6s%20s%20s%20s reserves a 6 characters-wide space for students[i].getStudID(), 20 characters-wide space for students[i].getFname(), 20 characters-wide space for students[i].getLname(), and 10 characters-wide space for students[i].getStatus().

System.out.printf("%6s%20s%20s%10s", students[i].getStudID() + " - ", students[i].getFname() + " ", students[i].getLname() + " - ", students[i].getStatus() + " ");

You can adjust the required space as per your requirement.

Learn more about it from the documentation of Formatter. You can also check this for some more examples and explanation.
