I want to let my game not end at any stage only for my chosen number

I created second method named displayOption2(); So I want to concentrate my displayOption2(); As you see i have new three options at ("1. Previous Game.") I need to go back my last chosen option. while at ("2. Starting New Game"); starts the game again, and at ("3. Exit the Game"); will only the option can end the game.

public static void main(String[] args) { Scanner reading = new Scanner(System.in); System.out.println(" Welcome UCT beginers Game we will test your IQ "); displayOption(); int input = reading.nextInt();

    switch (input){
            case 3:
                System.out.println("       Welcome You will have three chances to play; Please Guess my number");
                break;
            case 5:
                System.out.println("       Welcome You will have Five chances to play; Please Guess my number");
                break;
            case 10:
                System.out.println("       Welcome You will have Ten chances to play; Please Guess my number");
                break;
            case 4:
                System.out.println("Game-kii waad ka baxday, Macsalaamo!");
                System.exit(0);
                break;
            default:
                System.out.println("Lambar Khaldan ayaa galisay, Please try again");
                System.exit(0);
                break;
        }
                int randomNumber = (int) (Math.random() * 50 - 1); 
                int guessNumber = reading.nextInt();

                for (int a = 1; a < input; a++) {


                if (randomNumber == guessNumber ){
                System.out.println("          Congratulation; You have earned "+input+" coins");
                break;
                }
                else if (randomNumber > guessNumber ){
                System.out.println("          Sorry Low number    ("+ a + "/"+input+")");
                }
                else if (randomNumber < guessNumber){
                System.out.println("          Sorry High number   ("+ a +  "/"+input+")");
                }
                guessNumber = reading.nextInt();
        }
                if(randomNumber != guessNumber) {
                System.out.println("Sorry!  we can't help you any more, You failed *****The number was "+ randomNumber);
                }
}
public static void displayOptions(){
    System.out.println("");
    System.out.println("");
    System.out.println("       Please select your level Game     ");
    System.out.println("3.  Three chances to play.");
    System.out.println("5.  Five chances to play");
    System.out.println("10. Ten chances to play");
    System.out.println("4.  Exit the Game");
}
public static void displayOptions(){
    System.out.println("");
    System.out.println("");
    System.out.println("       We offered you these new options, please make your choice!   ");
    System.out.println("1.  Previous Game.");
    System.out.println("2.  Starting New Game");
    System.out.println("3.  Exit the Game");
