我有以下任务:
最多可能有十支队伍。并行数组用于存储团队名称,并跟踪获胜次数,加班损失和积分。输入最后一个团队的结果后,程序将按照输入顺序相反的顺序输出每个团队的记录摘要。
注意:“ W”值得2分,“ L”值得0分,“ O”值得1分
输入样例:
3 //Option number
Toronto //phrase
W //letters that loop in a while loop
W
L
O
W
O
W
N //To close the while loop, "N" is entered
Montreal
L

Vancouver

Winnipeg

Q //To close the while loop and get all the results, "Q" is entered
样本输出(以相反顺序输出结果):
Team W O L P //States that first, Team and then Wins, Overtime, Losses, and then points. "W" is 2 points, "O" is 1 point, and "L" is 0 point
Winnipeg 8 2 3 18
Vancouver 2 2 1 6
Montreal 1 1 6 3
Toronto 4 2 1 10
我对选项2做了类似的任务,不需要使用数组,现在这是选项3,仅需要使用并行数组
选项2代码:
else if (option == 2){
int pointsW = 0;
int pointsL = 0;
int pointsO = 0;
int counter = 0;
int totalpoints = 0;
String phrase = keyboard.next();
while(go){
String letter = keyboard.next();
if (letter.equals("W")){
pointsW+=2;
}
else if (letter.equals("L")){
pointsL+=0;
}
else if (letter.equals("O")){
pointsO+=1;
}
counter++;
if (letter.equals("N")){
totalpoints = pointsW + pointsL + pointsO;
counter--;
go = false;
}
}
int counter2 = 0;
int totalpoints2 = 0;
int pointsW2 = 0;
int pointsL2 = 0;
int pointsO2 = 0;
String phrase2 = keyboard.next();
while (go2){
String letter = keyboard.next();
if (letter.equals("W")){
pointsW2+=2;
}
else if (letter.equals("L")){
pointsL2+=0;
}
else if (letter.equals("O")){
pointsO2+=1;
}
counter2++;
if (letter.equals("Q")){
counter2--;
totalpoints2 = pointsW2 + pointsL2 + pointsO2;
go2 = false;
}
}
System.out.println(phrase + " has played "+counter+" games and has earned "+totalpoints+" points");
System.out.println(phrase2 + " has played "+counter2+" games and has earned "+totalpoints2+" points");
if (totalpoints > totalpoints2){
int wins = totalpoints - totalpoints2;
System.out.println(phrase + " is in first place by "+ wins + " points");
}else{
int wins2 = totalpoints2 - totalpoints;
System.out.println(phrase2 + " is in first place by "+ wins2 + " points");
}
}
如何将并行阵列合并到选项3中,并且具有与选项2相同的想法?对于学习并行数组,我真的很陌生,无法在线上找到有关它的任何帮助。
您需要名称,胜利,失败,加班和分数的数组。但是,当您了解更多信息时,可以通过创建自定义类型say来更好地进行管理,该自定义类型say Game
将具有,等属性name
,并具有List
用于记录获胜,失败,加班等情况的type属性。
import java.util.Scanner;
public class Standings {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.print("Enter option: ");
int option = keyboard.nextInt();
// Number of teams
int teams = 10;
// Array for team names
String[] teamNames = new String[teams];
// Array to record total wins for each team
int[] wins = new int[teams];
// Array to record total overtimes for each team
int[] overtimes = new int[teams];
// Array to record total losses for each team
int[] losses = new int[teams];
// Array for team points
int[] points = new int[teams];
// Variable to be used as a counter for the number of games
int i;
if (option == 3) {
// Label to to be used to quit as per user's choice
exit:
// Input and calculation
for (i = 0; i < teams; i++) {
String letter;
boolean go = true;
System.out.print("Enter the name of team " + (i + 1) + ": ");
teamNames[i] = keyboard.next();
while (go) {
System.out.print("Enter W/L/O for match result or N to end the game for this team: ");
letter = keyboard.next();
if (letter.equals("W")) {
wins[i]++;
} else if (letter.equals("O")) {
overtimes[i]++;
} else if (letter.equals("L")) {
losses[i]++;
} else if (letter.equals("N") || letter.equals("Q")) {
points[i] = wins[i] * 2 + overtimes[i];
go = false;
if (letter.equals("Q")) {
break exit;
}
}
}
}
// Output
System.out.println("Team W O L P");
for (int j = i; j >= 0; j--) {
System.out
.println(teamNames[j] + " " + wins[j] + " " + overtimes[j] + " " + losses[j] + " " + points[j]);
}
}
}
}
运行示例:
Enter option: 3
Enter the name of team 1: One
Enter W/L/O for match result or N to end the game for this team: W
Enter W/L/O for match result or N to end the game for this team: W
Enter W/L/O for match result or N to end the game for this team: L
Enter W/L/O for match result or N to end the game for this team: O
Enter W/L/O for match result or N to end the game for this team: N
Enter the name of team 2: Two
Enter W/L/O for match result or N to end the game for this team: L
Enter W/L/O for match result or N to end the game for this team: L
Enter W/L/O for match result or N to end the game for this team: O
Enter W/L/O for match result or N to end the game for this team: W
Enter W/L/O for match result or N to end the game for this team: Q
Team W O L P
Two 1 1 2 3
One 2 1 1 5
