对不起

这个问题是不允许的，我受到了严厉的批评

您可以通过简单地添加while或do-while循环来做到这一点

更新了你的方法。查看：

private void moduleSelection() {
    int choice = -1;

    while (true) { 
        System.out.println("1\t Algorithms");
        System.out.println("2\t Advanced Programming");
        System.out.println("3\t Computer Architecture and Operating Systems");
        System.out.println("4\t Artificial intelligence and Machine Learning");
        System.out.println("5\t Computer and Mobile Networks");
        System.out.println("6\t Software Engineering");
        System.out.println("7\t Big Data Analyics");
        System.out.println("8\t Cyber Security Threats");
        System.out.println("9\t Research Methods");
        System.out.println("10\t Research Project Proposal");
        System.out.println("11\t Individual Research Project");
        System.out.println("0\t Exit");
        System.out.println("Please entire your Module choice");

        choice = scanner.nextInt();
        switch (choice) {
        case 0:
            System.exit(1);
            break;
        case 1:
            System.out.println("Algorithms");
            break;
        case 2:
            System.out.println("Advanced Programming");
            break;
        case 3:
            System.out.println("Computer Architecture and Operating Systems");
            break;
        case 4:
            System.out.println("Artificial intelligence and Machine Learning");
            break;
        case 5:
            System.out.println("Computer and Mobile Networks");
            break;
        case 6:
            System.out.println("Software Engineering");
            break;
        case 7:
            System.out.println("Big Data Analytics");
            break;
        case 8:
            System.out.println("Cyber Security Threats");
            break;
        case 9:
            System.out.println("Research Methods");
            break;
        case 10:
            System.out.println("Research Project Proposal");
            break;
        case 11:
            System.out.println("Individual Research Project");
            break;
        default:
            System.out.println("Please select a valid Module");
            break;
        }
    }
}
