7-1 打球过程 (20分)
利用模板方法来构造相关类实现下述过程: 各种球类的玩法虽然不同,但是球类比赛的过程是类似的,都包含如下几个步骤: 1球员报道–>2比赛开始–>3比赛–>4比赛结束–>5公布比赛成绩,且其中1 2 4步相同 第3步根据球类不同,玩法不同,第5步根据得分不同,公布方式结果不同 构造类BallMatch表示球类比赛,包含方法compete表示真个比赛过程 构造各个比赛过程的函数checkin,start,play,end,annouceResult 打印信息如下: now checking in now starting now playing football now ending now annoucing result: 2-3 构造类FootballMatch和BasketBallMatch,实现具体的比赛过程。
在main函数中,读入整数i,如果为1,则构造一个足球比赛过程,如果为2则构造一个篮球比赛过程 打印比赛过程
输入格式:
比赛类型 比分
输出格式:
比赛过程信息
输入样例:
在这里给出一组输入。例如:
1 2-3
输出样例:
在这里给出相应的输出。例如:
now checking in
now starting
now playing football
now ending
now annoucing result: 2-3
答案1:
(考试时如果没有时间了这么写吧。。)
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
int i=in.nextInt();
String score=in.next();
if(i==1) {
System.out.println("now checking in");
System.out.println("now starting");
System.out.println("now playing football");
System.out.println("now ending");
System.out.println("now annoucing result: "+score);
}else if(i==2) {
System.out.println("now checking in");
System.out.println("now starting");
System.out.println("now playing basketball");
System.out.println("now ending");
System.out.println("now annoucing result: "+score);
}
}
}
答案2:
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
int i=in.nextInt();
BallMatch test=new BallMatch();
if(i==1) {
FootBallMatch f=new FootBallMatch(in.next());
test.compete(f);
}else if(i==2) {
BasketBallMatch f=new BasketBallMatch(in.next());
test.compete(f);
}
}
}
class FootBallMatch{
String score;
public FootBallMatch(String s) {
this.score=s;
}
public void checking () {
System.out.println("now checking in");
}
public void starting() {
System.out.println("now starting");
}
public void playing () {
System.out.println("now playing football");
}
public void ending() {
System.out.println("now ending");
}
public void annoucing () {
System.out.println("now annoucing result: "+this.score);
}
}
class BasketBallMatch{
String score;
public BasketBallMatch(String s) {
this.score=s;
}
public void checking () {
System.out.println("now checking in");
}
public void starting() {
System.out.println("now starting");
}
public void playing () {
System.out.println("now playing basketball");
}
public void ending() {
System.out.println("now ending");
}
public void annoucing () {
System.out.println("now annoucing result: "+this.score);
}
}
class BallMatch{
public static void compete(Object o) {
if(o instanceof FootBallMatch) {
FootBallMatch f=(FootBallMatch)o;
f.checking();
f.starting();
f.playing();
f.ending();
f.annoucing();
}else if(o instanceof BasketBallMatch) {
BasketBallMatch f=(BasketBallMatch)o;
f.checking();
f.starting();
f.playing();
f.ending();
f.annoucing();
}
}
}
