+Exercise 2.29 How can we tell from just its header that setPrice is a method and not a constructor?
+public void setPrice(int ticketCost)
+
+	Has a void.
+	Takes a parameter.
+
+
+
+
+Exercise 2.30 Complete the body of the setPrice method so that it assigns the
+value of its parameter to the price field.
+
+	public void setPrice(int ticketCost){
+		price = ticketCost;
+	}
+
+
+
+
+Exercise 2.31 Complete the body of the following method, whose purpose is to
+add the value of its parameter to a field named score.
+  /**
+   * Increase score by the given number of points.
+   */
+  public void increase(int points)
+  {
+  	points += points;
+
+ }
+
+
+
+
+Exercise 2.32 Can you complete the following method, whose purpose is to sub- tract the value of its parameter from a field named price?
+  /**
+   * Reduce price by the given amount.
+   */
+  public void discount(int amount)
+  {
+
+  	price -= amount;
+
+... }
+
+
+Exercise 2.33 Add a method called prompt to the TicketMachine class. This should have a void return type and take no parameters. The body of the method should print something like:
+  Please insert the correct amount of money.
+
+
+
+Exercise 2.34 Add a showPrice method to the TicketMachine class. This should have a void return type and take no parameters. The body of the method should print something like:
+The price of a ticket is xyz cents.
+where xyz should be replaced by the value held in the price field when the method
+is called.
+
+
+
+Exercise 2.35 Create two ticket machines with differently priced tickets. Do calls to their showPrice methods show the same output, or different? How do you explain this effect?
+
+
+Exercise 2.36 What do you think would be printed if you altered the fourth state- ment of printTicket so that price also has quotes around it, as follows?
+  System.out.println("# " + "price" + " cents.");
+
+
+
+
+Exercise 2.37 What about the following version? System.out.println("# price cents.");
+
+
+
+Exercise 2.38 Could either of the previous two versions be used to show the price of tickets in different ticket machines? Explain your answer.
