题目与思想详见第二次作业。
感觉javabean用起来比session方便，毕竟是一个自己定义可以随便使用的java类。
javabean：（guess.java）
package anyi;
public class guess {
private int num;
private int tem;
private int time=1;
public guess() {
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public int getTem() {
return tem;
}
public void setTem(int tem) {
this.tem = tem;
}
public int getTime() {
return time;
}
public void setTime(int time) {
this.time = time;
}
}
第一个JSP页面：（frist.jsp）
