Java数据结构跳舞配对问题（队列的应用）
代码如下，可以直接运行。
public static void main(String[] args) {
final int M = 6; // number of girls，可改动
final int N = 7; // number of boys，可改动
int x = 3;// some boy，可改动
int y = 5;// some girl，可改动
String result = "";// 记录结果，即第二个问题
// 初始化，假设队列存放男女生编号，从1开始
QueueInteger boys = new LinkedListInteger();
for (int i = 1; i = N; i++) {
boys.add(i);
}
QueueInteger girls = new LinkedListInteger();
for (int i = 1; i = M; i++) {
girls.add(i);
}
// 跳舞开始
int min = boys.size() girls.size() ? girls.size() : boys.size();
int k = 1;// songs
int count = 2; // 求出两个值，可改动
while (k 1000) {//为了不死循环，这里假设最多有999支舞蹈
System.out.println("***This is the " + k + "st dance:");
for (int i = 0; i min; i++) {
// 跳舞，第一个问题：输出每曲配对情况
System.out.println("Boy " + boys.peek() + " = Girl "
+ girls.peek());
// 跳过的排到对尾
int boy = boys.remove();
boys.add(boy);
int girl = girls.remove();
girls.add(girl);
// 判断 x和y跳舞了没有
if (boy == x girl == y) {
result += k + ",";
count--;
}
}
if (count == 0)
break;
// next dance
k++;
}
// 结果
if (count == 0)
System.out.println("\n***Boy " + x + " and Girl " + y
+ " dance together in : " + result);//第二个问题的解答，跳了哪几支舞
else
System.out.println("\n***Boy " + x + " and Girl " + y
+ " have no chance to dance!");//第二个问题的解答，两人没机会跳舞
}
java web开发部 有两个下拉框,我要做的是在选完第一个下拉框时,第二个下拉框才可选,代码该怎样写
第一个下拉框绑定一个onchange事件，第二个下拉框保持为没有选项，当选中第一个下框某项时在动态获取第二个下拉框的内容
一道Java的编程题~~！！
