Please follow the code and comments for description :

CODE :

import java.io.BufferedWriter; // required imports
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class StudentInfo { // class to run the code

    public static void main(String[] args) { // driver method
        try { // try catch block of code
            File file = new File("studentData.txt"); // get the file object for the text file, provide the whole path directory if is out of the java program's class directory
            int sId[] = {123, 150, 999, 100, 225, 849, 123, 123, 150, 643}; // required variables
            String fname[] = {"Tim", "Diablo", "Tom", "Buffy", "LeRoy", "Bruce", "Tom", "Dick", "Harry", "Jane"};
            String lname[] = {"Smith", "Ho", "Doe", "Slayer", "Jackson", "Lee", "Smith", "Smith", "Ho", "Doe"};
            String dob[] = {"19960215", "19900420", "19860215", "19960314", "20001114", "19560215", "19890130", "19880615", "19870420", "19860210"};
            String addr[] = {"777 Heaven Way", "666 Hells Gate", "999 NeverMind", "456 Seven", "123 Right Here Alley", "333 Enter The Dragon", "321 Zero", "836 Pick Up Sticks", "577 Eleven", "888 Haight"};

            // if file doesnt exists, then create it
            if (!file.exists()) {
                System.out.println("Creating the File..."); // message
                file.createNewFile(); // call the method to create the file
            }

            FileWriter fw = new FileWriter(file.getAbsoluteFile()); // create the writer object for the file
            BufferedWriter bw = new BufferedWriter(fw); // buffered writer class for the file writer
            System.out.println("Writing Data to the File..."); // message
            bw.write(String.format("%-15s %-15s %-15s %-15s %-15s", "StudentID#", "First Name", "Last Name", "DOB", "Address")); // format the header
            bw.write("\n"); // new line character
            for (int i = 0; i < 10; i++) { // iterate over the index values
                int id = sId[i]; // get the respective values
                String fn = fname[i];
                String ln = lname[i];
                String birth = dob[i];
                String add = addr[i];
                bw.write(String.format("%-15s %-15s %-15s %-15s %-15s", id, fn, ln, birth, add)); // write the formatted data to file
                bw.write("\n"); // new line character
            }
            bw.close(); // close the file

            System.out.println("Completed Writing Data to the File."); // message

        } catch (IOException e) { // catch any exceptions
            e.printStackTrace();
        }
    }
}

OUTPUT :

Creating the File...
