while loop keeps looping endlessly. after option2 it is suppose to return to the top of the while loop but when it happens, it keep repeating

Question

If i loop at option1 = 2 it will keep printing the whole menu. i want it to loop back to the top just once instead of it repeatedly print it. just cannot seem to do this while loop properly. If i loop at option1 = 2 it will keep printing the whole menu. i want it to loop back to the top just once instead of it repeatedly print it. just cannot seem to do this while loop properly.

int option1 = 0;
    
while(option1 != -1){
    mainMenu();        //assuming i have the main menu function
    while(valid2 == false){
        System.out.println("Please Enter a Option: ");
        // Get input from keyboard
        strOption1 = in1.nextLine();
        try{
            option1 = Integer.parseInt(strOption1);
            valid2 = true;
        }
        catch(NumberFormatException e){
        System.out.println("Error, Please Enter Again. ");
}        
}




if (option1 == 1){    
int option2 = 0;

    while (option2 != -1){
        System.out.println("1.Add a new Hawker Food Stall ");
        System.out.println("2.Delete a specific Hawker Food Stall ");
        System.out.println("Please Enter a Option: ");
        Scanner in = new Scanner(System.in);

        while(valid3 == false){

                valid3 = true;
            }   
            catch(NumberFormatException e){
            System.out.println("Error, Please Enter Again. ");
            }
        }

        if (option2 == 1){

        }
