头一次引用循环～我这样用对吗？

[凉岑玉]

我是第一次引用【do...while】循环，代码如下～希望大家指出我的错误或者漏洞～
import java.util.Random;
import java.util.Scanner;

public class shaizi {

/**
* @param args
*
*/
public static void main(String[] args) {
System.out.println("请输入任意字符并回车开始游戏");
Scanner scan = new Scanner(System.in);
String a;
Random w = new Random();
int computer = w.nextInt(6) + 1;
int player = w.nextInt(6) + 1;
int number = 0;
int c=0;
int p=0;
a = scan.next();


do {
System.out.println("电脑掷出了" + player + "点");
a = scan.next();
System.out.println("玩家掷出了 " + computer + "点");
number++;
if (player > computer) {
System.out.println("对不起，您输了，快给钱！！");
c++;

} else if (player == computer) {
System.out.println("点数相等，双方各拿出20元给程序设计者");
} else {
System.out.println("恭喜啊～好不容易赢一次！！来，给你20块钱！");
p++;
}
System.out.println("是否查看结果?(y/n)");
a = scan.next();
if (a.equals("y")) //equals：等于。
{
System.out.println("总共玩了" + number + ",电脑赢了" + c
+ ",您赢了" + p + ".");
}
System.out.println("是否继续？(y/n)");
a = scan.next();
} while (a.equals("y"));
System.out.println("是否退出?(y/n)");
a = scan.next();
if (a.equals("y")) {
System.out.println("您已成功退出");
} else {
System.out.println("是否继续(y/n)");
a = scan.next();
}
while (scan.equals("y"));


}
}

随机数在程序开始就设定了，而循环中没有改变随机数。这样每次运行都一个结果。
把随机数的赋值放到循环里吧

[justlearn]

int computer;
int player; int number = 0;
int c=0;
int p=0;
a = scan.next();


do {
player = w.nextInt(6) + 1; System.out.println("电脑掷出了" + player + "点");
a = scan.next();
computer = w.nextInt(6) + 1; System.out.println("玩家掷出了 " + computer + "点");
number++;
if (player > computer) {
System.out.println("对不起，您输了，快给钱！！");
c++;

}
