thanks, have fixed it

Hi people. I have also posted this in I/O and Streams topic as not sure where this belongs. I have a few problems at the moment. Below is my incomplete program. It compiles but doesn't do a whole lot when run. I am doing a project on polymophism and inheritance. I have a footwear class(parent) and sneaker & thong classes(children)...my switch statements don't do anything. I'm trying to setColour to "something"(eg: whatever option user chooses), then it is written to a file. What's going on?
import java.io.* ; abstract class Footwear { protected String colour ; protected String material ; protected String brand ; protected int choice ; //constructor public Footwear() { System.out.println("Choose a footwear colour") ; System.out.println("------------------------") ; System.out.println("1. Red") ; System.out.println("2. Blue") ; System.out.println("3. White") ; System.out.println("Your Colour:") ; BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in)) ; try { choice = Integer.parseInt(stdin.readLine()) ; do { switch(choice) { case 1: setColour("Red") ; break ; case 2: setColour("Blue") ; break ; case 3: setColour("White") ; break ; default: System.out.println("Enter number 1, 2, or 3:") ; } }while(choice != 1 || choice != 2 || choice != 3) ; } catch(IOException ioe) { System.out.println("What a catch!") ; } } /*//default constructor public Footwear() { colour = "No Colour" ; material = "No Material" ; //brand = "Home Brand" ; }*/ //methods protected void setColour(String col) { colour = col ; } public String getColour() { return colour ; } protected void setMaterial(String mat) { material = mat ; } public String getMaterial() { return material ; } protected void toFile() { try { PrintWriter priWri = new PrintWriter(new FileWriter("output.txt")) ; priWri.println(getColour()) ; priWri.close() ; } catch(IOException ioe) { System.out.println("What a catch!!") ; } } //abstract method in parent class that is used //in the two child classes public abstract void howToWear() ; } //Child class class Sneakers extends Footwear { /*public Sneakers(String col, String mat) { super(col, mat) ; }*/ public void howToWear() { System.out.println("You have to tie up the laces") ; } } //Child class class Thongs extends Footwear { /*public Thongs(String col, String mat) { super(col, mat) ; }*/ public void howToWear() { System.out.println("You just slip them on") ; } } //Main method that instantiates the two child classes class Driver { public static void main(String[]args) { Sneakers mySneakers = new Sneakers() ; mySneakers.toFile() ; } }
