按花色和牌大小排序，红桃>方块>黑桃>梅花。

大概思路：新建Card对象，属性有

private int id; //花色，1234对应红方黑梅  
private int values; //数字1-13依次对应牌值12345678910JQK

分别对它们赋权值，values权值为本身，红桃权值13，方块26，黑桃39，梅花42，最后根据权值大小排序即可。

public class Card {
    	
    	private int id; //花色，1234对应红方黑梅
    	private int values; //牌值12345678910JQK
    	public int getId() {
    		return id;
    	}
    	public void setId(int id) {
    		this.id = id;
    	}
    	public int getValues() {
    		return values;
    	}
    	public void setValues(int values) {
    		this.values = values;
    	}
    	
    }

    public class cardsSort2 {
    	public static void main(String[] args) {
    		List<Card> cards = new ArrayList<Card>(10);
    		String[] v = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
    		for (int i = 0; i < 10; i++) {

    	public static String getId(int id) {

代码有很多地方可优化，主要还是看思路吧，权值的赋予，冒泡的使用。
