按照我的思路，需要?jiǎng)?chuàng)建一個(gè)類PokerComparator用以比較黑、紅、梅、方

我暫時(shí)如上寫免于報(bào)錯(cuò)

如何更改或者補(bǔ)全呢？

另外，addPokerToDeal()中的一部分內(nèi)容，我曾試圖移到go()中去，然后調(diào)用

結(jié)果失敗了，只好注釋掉，見注釋部分

public?static?void?main(String[]?args)?{
		//?TODO?Auto-generated?method?stub
		Test?t=new?Test();
		t.addPokerToDeal();
		t.playerAndDeal();
		t.go(p1,?p2);???這句不行

	}

因?yàn)檎{(diào)用時(shí)參數(shù)有問題，t.go()怎么寫都不對(duì)，怎樣才能完成調(diào)用？

你最好按照代碼語言（選擇JAVA），分開來發(fā)上來，這樣看的太亂了，你也沒說你有什么錯(cuò)誤啊，或者運(yùn)行報(bào)了什么錯(cuò)？如果不能運(yùn)行的話，那就是代碼還沒完成，繼續(xù)修改，可以參照下評(píng)論里的，我就是參照了下評(píng)論的，然后代碼優(yōu)化了很多
