I am a college student just learning the basics of programming in Java. I was given the task of recreating the game of NIM playing against a computer. The rules I was given where that there are 3 piles of 10, you can remove any amount from one pile at a time and the one to remove the last point loses the game.

This is what I currently have done, it plays through one turn for the user and one turn for the computer. I know I need to loop this process until the game is over but am not sure how or the best way to do so.

public class Assing3 

 public static void main(String args) 

 Nim test = new Nim();

 test.playerTurn();
 test.calculate();
 test.computerTurn();
 test.display();

public class Nim 

 Scanner input = new Scanner(System.in);
 Random num = new Random();

 private String pile;
 private int a, b, c, remove;
 private boolean turn = true;

 private int compPile = num.nextInt(2);
 private int compRemove = num.nextInt(9) + 1;

 public Nim() 
 a = 10;
 b = 10;
 c = 10; 
 

 public void playerTurn() 
 System.out.println("Welsom to the game of NIM");
 System.out.println("We will use the misère rules...");
 //display the the piles and size
 System.out.println("tAtBtC");
 System.out.println("t" + a + "t" + b + "t" + c);

 //user trun
 while (turn == true) //end true while 1

 while (turn == true) //select number to remove
 System.out.println("How many do you want to remove from the: " + pile + " pile?");
 remove = input.nextInt();

 if (remove > 0) else 
 System.err.println("Must ener a number greater then 0...");
 

 //end true while 2

 turn = false;
 //end of play method

 public void computerTurn() 
 System.out.println("It is now the computers turn...");
 System.out.println("The computer is removing: " + compRemove + " from the: " + compPile + " pile...(0 = a, 1 = b, 2 = c ");

 while (turn == false) 

 if (compPile == 0) 
 if (a == 0) 
 compPile = num.nextInt(2);
 System.err.println("Selected pile is empty... New pile is: " + compPile);
 continue;
 else if (compRemove > a) 
 compRemove = num.nextInt(a) + 1;
 System.err.println("The amount the computer wanted to remove is to hight... New number to be removed is: " + compRemove);
 continue;
 else 
 a = a - compRemove;
 
 

 if (compPile == 1) 
 if (b == 0) 
 compPile = num.nextInt(2);
 System.err.println("Selected pile is empty... New pile is: " + compPile);
