Modify the compareTo method so it orders Student objects based on the lexicographic ordering of the name variable. Without modification to the main method, the program should now output the students ordered by name and number

import java.util.Arrays;

public class StudentTest

{

public static void main(String[] args)

{

Scanner170 keyboard = new Scanner170(System.in);

Student[] s = new Student[5];

s[0] = new Student("Mark" , 329);

s[1] = new Student("Roy" , 543);

s[2] = new Student("Bob" , 237);

s[3] = new Student("Sam" , 764);

s[4] = new Student("John" , 642);

Student2[] ss = new Student2[5];

ss[0] = new Student2("Mark" , 329);

ss[1] = new Student2("Roy" , 543);

ss[2] = new Student2("Bob" , 237);

ss[3] = new Student2("Sam" , 764);

ss[4] = new Student2("John" , 642);

Arrays.sort(s);

for(Student s1:s )

System.out.println(s1);

System.out.println(" ");

Arrays.sort(ss);

for(Student2 ss1:ss )

System.out.println(ss1);

}
