Hello All, I am working on a java project and I want to know the source code of the Web Medical Management System Project. Basically, By using this application, patients can reserve online meetings with their preferred specialists. Specialists can recommend medical services, e-remedy, and consider the patient’s clinical records, lab reports, and many more. The app also lets users explore and interface with individuals who are donating their organs or blood. During the times of the pandemic, when it gets dangerous to visit the hospital, this JAVA project comes to your rescue. The application comes with two modules — an Admin and a Doctor module and I have taken the details of this project on Interviewbit platform. Can anyone provide me the source code of the web medical system?

Hello All, I am trying to make a simple menu using a do-while loop in java. I have used this source to run the code and its looks like this:

 int choice;
    Scanner scanChoice = new Scanner(System.in);
    do {
        System.out.println("Pick an option. 1 2 or 3.";
        System.out.println("1. Apple";
        System.out.println("2. Pear";
        System.out.println("3. Pineapple";

        choice = scanChoice.nextInt();
    } while (choice < 1 || choice > 3);

    System.out.println("You picked " + choice);

The problem is, every time I try to run it, it throws "java.util.NoSuchElementException". The full error is below:

Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Scanner.java:862)
at java.util.Scanner.next(Scanner.java:1485)
at java.util.Scanner.nextInt(Scanner.java:2117)
at java.util.Scanner.nextInt(Scanner.java:2076)
at mainPackage.Main.fruitMenu(Main.java:135)
at mainPackage.Main.main(Main.java:103)

I know that this is because scanChoice.hasNextInt() returns false, but I'm not sure how to fix this. When I add an if statement (if (scanChoice.hasNextInt())), the method scanChoice.hasNextInt() still returns false, so it just passes over the line that initializes the variable choice, and that variable never gets initialized.

Anyone know how to fix this? Any suggestions?
