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。

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]); } } } }
