java - 使用数组生成玩家得分

Question

我正在尝试使用数组方法来跟踪我的游戏得分，但当我尝试编译和运行时，我遇到了困难。

import java.util.Scanner;
import java.io.*;

public class score
{

    public static void main (String[]args)
    {

    Scanner scan = new Scanner(System.in);

    int [] arrPlayer = new int[7];

    System.out.println("Please Enter Your Score");
    arrPlayer[0]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[1]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[2]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[3]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[4]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[5]=scan.nextInt();
    System.out.println("Please Enter Your Score");
    arrPlayer[6]=scan.nextInt();

    System.out.println("Player 1 : Score: "arrPlayer[0];
    System.out.println("Player 1 : Score: "arrPlayer[1];
    System.out.println("Player 1 : Score: "arrPlayer[2];
    System.out.println("Player 1 : Score: "arrPlayer[3];
    System.out.println("Player 1 : Score: "arrPlayer[4];
    System.out.println("Player 1 : Score: "arrPlayer[5];
    System.out.println("Player 1 : Score: "arrPlayer[6];

    for(int i=0;i<7;i++);

    }

}

Answer 1

您错过了将数组值与字符串连接起来的 + 。而且您也没有关闭 System.out.println() 方法。

更正如下:

    System.out.println("Player 1 : Score: " + arrPlayer[0]);
    System.out.println("Player 1 : Score: " + arrPlayer[1]);
    System.out.println("Player 1 : Score: " + arrPlayer[2]);
    System.out.println("Player 1 : Score: " + arrPlayer[3]);
    System.out.println("Player 1 : Score: " + arrPlayer[4]);
    System.out.println("Player 1 : Score: " + arrPlayer[5]);
    System.out.println("Player 1 : Score: " + arrPlayer[6]);

还有奖励:

您可以利用循环进行以下更改来简化代码。

for (int i = 0; i < 7; i++) {
    System.out.println("Please Enter Your Score");
    arrPlayer[i] = scan.nextInt();
}

for (int i = 0; i < 7; i++) {
    System.out.println("Player 1 : Score: " + arrPlayer[i]);
}
