Define a class that accepts a student's registration number as input, extracts the relevant details, and displays them in the specified format.

import java.util.Scanner;

public class KboatStuRegNum
{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter reg. no.: ");
        _______(1)_________
        
        int l = n.length();
        if (l != 12) {
            System.out.println("Invalid reg. no.");
            System.exit(0);
        }   
        
        _______(2)_________
        _______(3)_________
        _______(4)_________
        _______(5)_________
        
        System.out.println("Course Code    : " + cc);
        System.out.println("Admission Year : " + yr);
        System.out.println("College Code   : " + cl);
        System.out.println("Roll Number    : " + rNo);
    }
}

A shopping website offers a special discount if the order ID has the sequence 555 anywhere in it. For example, 158545553031, 198555267140, …. .

Fill in the blanks (a) and (b) in the given Java Method to convert the order ID (a long integer) into a string and check if the sequence 555 is present in it.

void checkOrder(long oid)
{
    String str = _______(a)_________;
    if(______(b)_______)
    {
        System.out.println("Special Discount Eligible: " + oid);
    }
}

The output of the statement "talent".compareTo("genius") is:

1. 11
2. –11
3. 0
4. 13

Write the output of the following String methods:

String x= "Galaxy", y= "Games";

(a) System.out.println(x.charAt(0)==y.charAt(0));

(b) System.out.println(x.compareTo(y));
