(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)
Examples of strings that can be accepted:
Jill, Allen
Jill , Allen
Jill,Allen
Ex:
Enter input string: Jill, Allen
(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)Ex:
Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen
(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts)Ex:
Enter input string: Jill, Allen First word: Jill Second word: Allen

Language: JAVA
Fill in your code for the following program that takes two words as input from the keyboard, representing a user ID and a password, then the program does the following:
If the user ID and the password match “admin” and “open”, respectively, then output “Welcome”.
If the user ID matches “admin” and the password does not match “open”, output “Wrong password”.
If the password matches “open” and the user ID does not match “admin”, output “Wrong user ID”.
Otherwise, output “Sorry, wrong ID and password”.
import java.util.Scanner;
public class Login{
public static void main(String[] args){
Scanner scan = ____ Scanner(________);//instantiate a Scanner object
String userID = scan._________; // read the user ID
String password = scan.__________; // read the password

Q1: Can you read this question carefully rebug and type the answers
Debug Problem 1:
As an intern for The Weather Channel, you have been instructed to debug a java program that
converts Celsius to Fahrenheit. If the formula runs correctly, then 12 degrees in Celsius should
give 54 degrees in Fahrenheit .
Here is the formula given and it might not be correctly stated in terms of () needed and the
order of operations. Google a reputable site if needed.:
°F = °C x 9/5 + 32
Remember that there may be more than one problem to fix. It could be that variables have an
incorrect data type. It could be that the formula is not coded correctly. Also, some import
statements could be missing. Copy and paste the code below in JGrasp and debug the code.
Here is the code to debug:
// Convert Celsius to Fahrenheit
class CelsiusToFahr
{
public static void main (String args[])
{
Scanner keyboard = new Scanner(System.in);
int celsius = 0;
int fahr = 0;
System.out.println("Input the degrees in…
