题目：两个乒乓球队进行比赛，各出三人。甲队为a,b,c三人，乙队为x,y,z三人。已抽签决定比赛名单。有人向队员打听比赛的名单。a说他不和x比，c说他不和x,z比，请编程序找出三队赛手的名单。
public class lianxi18 {
static char[] m = { "a", "b", "c" };
static char[] n = { "x", "y", "z" };
public static void main(String[] args) {
for (int i = 0; i < m.length; i++) {
for (int j = 0; j < n.length; j++) {
if (m[i] == "a" && n[j] == "x") {
continue;
} else if (m[i] == "a" && n[j] == "y") {
continue;
} else if ((m[i] == "c" && n[j] == "x")
|| (m[i] == "c" && n[j] == "z")) {
continue;
} else if ((m[i] == "b" && n[j] == "z")
|| (m[i] == "b" && n[j] == "y")) {
continue;
} else
System.out.println(m[i] + " vs " + n[j]);
}
}
}
