True or false game doesn't work after 1st round

Question

I am new to java, this is my first program I've been developing. Basically, you enter '1', and that enters you to the game.

Sets level to 1.

Then, it will select a question, based on the level. First round works fine. After I answer correctly on round 1, It moves me to question 2.

But in question 2, if I answer correctly, it will stick on question 2 and repeat it instead of moving to the next question.

Why is it doing that? I have level++?

    public static void main (String[] args) {
        gameRoom();
    }

    public static void gameRoom() {
        System.out.println("Welcome to the Truth and False game!");
        System.out.println("Please write 1 to start, or -1 to exit program.");
        InputI = console.nextInt();

        if(InputI == 1) {
            inGame = true;
            gameProcess(1);
        }
    }

    public static void gameProcess(int level) {

        switch (level) {

            case 1:
                question = tof.getQuestion(1);
                System.out.println("Your question is: " + question);
                System.out.println("Please answer, true or false!.");
                level = 1;
            break;

            case 2:
                question = tof.getQuestion(2);
                System.out.println("Your question is: " + question);
                System.out.println("Please answer, true or false!.");   
                level = 2;
            break;

            case 3:
                System.out.println("Hey1");
            break;
        }

        while (inGame) {
            InputS = console.nextLine();
            while (InputS != "") {
                inGame = false;                 
                InputS = console.nextLine();
                checkQuestion(level, InputS);               
            }
        }
    }

    public static void checkQuestion (int level, String question)
    {
        Boolanswer = tof.checkQuestion(level, question);
        level++;
        if (Boolanswer) {
            System.out.println("Correct!" + correctAnswers);
            correctAnswers++;
        } else {
            System.out.println("Incorrect! " + correctAnswers);             
        }

        inGame = true;
        gameProcess(level);
    }

The problem might be that, the system can't read the loop while input != "", I may be wrong though, this is the other class:

    private String[][] questionsArray = new String[][]
    {
        {"Is sky blue?", "true"},
        {"Is sky green?", "false"}
    };

    private String answer = "";
    private String Currentanswer = "";
    private String question = "";
    private int level = 0;
    private boolean returnValue = false;

    public String getQuestion(int Level) {
        switch (Level) {

        case 1:
            question = questionsArray[0][0];
        break;

        case 2:
            question = questionsArray[1][0];
        break;      
        }

        return question;
    }

    public String getAnswer(int Level) {
        switch (Level) {

            case 1:
                answer = questionsArray[0][1];
            break;

            case 2:
                answer = questionsArray[1][1];
            break;          
        }

        return answer;
    }   

    public boolean checkQuestion(int level, String answer) {

        switch (level) {
            case 1:
                Currentanswer = questionsArray[0][1];
                if (Currentanswer.equalsIgnoreCase(answer)) {
                    returnValue = true;
                } else {
                    returnValue = false;
                }
            break;

            case 2:
                Currentanswer = questionsArray[1][1];
                if (Currentanswer.equalsIgnoreCase(answer)) {
                    returnValue = true;
                } else {
                    returnValue = false;
                }
            break;              
        }
        return returnValue;
    }

Problem is, when I answer correctly, the second question, it will print nothing. and if I answer not correctly, it will move to the FIRST question.

I only have 2 questions, I know, but I am just testing. Level should go to 3, and print "Hey!" according to the switch cases.

Answer 1

You don't support level > 2

 public String getQuestion(int Level) {
    switch (Level) {

    case 1:
        question = questionsArray[0][0];
    break;

    case 2:
        question = questionsArray[1][0];
    break;      
    }

    return question;
}

Your question = questionsArray[1][0]; stays for any level other than 1 or 2.

If you send level 3 then switch does nothing and previos question is returned,

Answer 2

The problem might be in this loop:

while (inGame) {
            InputS = console.nextLine();
            while (InputS != "") {
                inGame = false;                 
                InputS = console.nextLine();
                checkQuestion(level, InputS);               
            }
        }

Try to replace while (InputS != "") with while (!InputS.equals("")) {
