Latest CS Project. Switching values in a Array

[jenxin]

Program 3: Square-Up

This is my assignment, I am currently on part E. I need to find out how arrange the values.

0 1 2 3 4 5 6
7 8 9 10 11 12 13
14 15 16 17 18 19 20

Lets say I choose row 1, my goal is for the values in the array of row 1, (0-6) to be assigned into 9,16,3,10,17,4,11; respectively.

I'm not sure how to do this while also shuffling the board. Any help is appreciated.

Here is a copy of my class Board:

import java.util.Random;          // allows getting a random number  
import java.util.Scanner;		  // allows user input from the keyboard
class Board {


// create the array of 52 cards
	public static void main(String[] args)  {
	Square[] cardDeck= new Square[52];

// setting up the deck
for (int x = 0; x <= 12; x++){
	int l=x+1;
	String y = "" + l;
	cardDeck[x] = new Square( 0,0, 40, "red", false, y);    // red 
		}
for (int x = 13; x <= 25; x++){
	int l=x-12;
	String y = "" + l;
	cardDeck[x] = new Square( 0,0, 40, "green", false, y);    // green 
			}
for (int x = 26; x <= 38; x++){
	int l=x-25;
	String y = "" + l;
	cardDeck[x] = new Square( 0,0, 40, "blue", false, y);    // blue 
			}
for (int x = 39; x <= 51; x++){
	int l=x-38;
	String y = "" + l;
	cardDeck[x] = new Square( 0,0, 40, "yellow", false, y);    // yellow 
			}
// output of original deck
System.out.println("The deck is:");

	for(int x=0; x<=51; x++){
		char theColor = cardDeck[x].getColor().charAt( 0);    
		String theNumber = cardDeck[x].getLabel();
		if (x<12){
			System.out.print(theColor+theNumber+"  ");
		}
		if (x==12){
			System.out.print(theColor+theNumber+"\n");
		}
