Assume that you have already successfully written a class named

Students
that handles student records for the Registrar’s office. Assume that the
Students
class:

• Contains a

studentIds
instance variable—an array of
ints
that contains student ID numbers.

• Contains a 1-parameter constructor that initializes the

studentIds
instance variable.

• Contains this

main
method:

public static void main(String[] args){     Students s1 = new Students(new int[] {123, 456, 789});     Students s2 = new Students(new int[] {123, 456, 789, 555});     Students s3 = new Students(new int[] {123, 456, 789});     if (s1.equals(s2))     {      System.out.println("s1 == s2");     }     if (s1.equals(s3))     {      System.out.println("s1 == s3");     }} // end main

Write a

public
method named
equals
for your
Students
class that tests whether two
Students
objects are equal. Your
equals
method should be written such that the above
main
method would produce this output:

s1 == s3

Only provide code for the asked-for

equals
method; do not provide code for the entire
Students
class.
