Метод не возвращает правильное значение (Java)

Question

public static char getChoice(char choice) { 
    System.out.println("\nTake or stop? (t/s): "); 
    choice = sc.next() 
     .charAt(0); 
    if (choice == 't') { 
     System.out.print("Player Took"); 
     choice = 't'; 

    } else if (choice == 's') { 
     System.out.println("Player didnt take"); 
     choice = 's'; 

    } 
    return choice; 
    //return answer; 
} 

Это часть в основном Thats назвав его

 //Checking if players score is 21 when the game begins 
    if(ptotal == 21) 
    { 
     System.out.print("\nPlayer wins!"); 
    } 
    //Checking if the computers score is 21 when the game 
    else if(ctotal == 21) 
    { 
     System.out.print("\nComputer wins!"); 
    } 
    //Checking if both scores are 21 which would be a tie 
    else if(ctotal == 21 && ptotal == 21) 
    { 
     System.out.print("\nTie!"); 
    } 
    //If none above is true it will proceed to the loop 
    else 
    { 
     //getChoice(answer); 
     while(ptotal < 21 && answer == 't')//Loop conditions 
     { 
      getChoice(answer); 
      //Prompting user if they would like to take or stop 
      /*System.out.println(); 
      System.out.print("Take or stop? (t/s): "); 
      answer = sc.next().charAt(0); 
      System.out.println("");*/ 


      //Checking if the input is 't' 
      if(answer == 't') 
      { 
       //If true another card will be generated and added to the total value 
       System.out.print("\nPlayer draws: "); 
       pCard = getCard(); 
       showCard(pCard); 
       ptotal += cardValue(pCard); 

      } 
      //Checking if input is 's' 
      else if(answer == 's') 
      { 
       System.out.println("Player Stops"); 
      } 
     } 

это должно спросить пользователя для ввода полукокса, а затем возвращают конкретный символ в зависимости от оператора if, но каждый раз, когда он возвращает его, когда я вызываю его из основного, он не будет отображать эти строки, но он не будет выбирать правильный символ. PLS помощи.
