2. Rohit is developing a user authentication system. The system should check if the entered username and password match the stored
username and password. The rules are as follows:
- If the username and password are correct, print "Access granted".
- If the username is correct but the password is incorrect, print "Incorrect password".
- If the username is incorrect, print "User not found".
Rohit writes the following code to implement these rules:
String storedUsername = "user123";
String storedPassword = "pass123";
String enteredUsername = "user123";
String enteredPassword = "pass124";
if (!enteredUsername.equals(storedUsername)) {
System.out.println("User not found");
} else if (!enteredPassword.equals(storedPassword)) {
System.out.println("Incorrect password");
} else {
System.out.println("Access granted");
}
What will be the output of the code?
a. User not found b. Incorrect password
c. Access granted d. Invalid credentials
