java - 通过输入与数据关联的名称来查找数据

我在这里为跑步者开发一个简单的统计程序。仅获取一场比赛的数据。在有stackoverflow的帮助后，我有第一部分运行的代码！
想法是，比赛结束后，我们可以输入跑步者的姓名和时间。我希望然后通过搜索一个人的姓名来搜索一个人的跑步时间（然后您会在屏幕上看到跑步者的姓名和他们的时间。在Java中可以这样做吗？谢谢Cassy。

这是我的代码...

import java.util.Scanner;


public class Trying
{

public static void main (String[] args)

    {
    int num;

    Scanner input= new Scanner (System.in);

    System.out.println("******************************************************************* ");
    System.out.println("Welcome to Running Race Time Statistical Analysis Application");
    System.out.println("******************************************************************* \n");


    System.out.println("Please input number of participants (2 to 10)");

    num=input.nextInt();

    // If the user enters an invalid number... display error message...
    while(num<2|| num >10)
    {
        System.out.println("Error invalid input! Try again! \nPlease input a valid number of participants (2-10)...");

        num=input.nextInt();
    }

    // declare arrays
    double resultArray [] = new double [num]; // create result array with new operator
    String nameArray [] = new String [num];// create name array with new operator
    // Using the num int will ensure that the array holds the number of elements inputed by user


    // loop to take in user input for both arrays (name and result)
    double count = 0;
    for (int i = 0 ; i < nameArray.length ; i++)
        {
            System.out.println ("Please enter a race participant Name for runner " + (i+1) );
            nameArray[i] = input.next();

            System.out.println ("Please enter a race result (time between 0.00 and 10.00) for runner " + (i+1) );
            resultArray[i] = input.nextDouble();

            count += resultArray[i]; // This count variable is used later to calculate average from total
        }
}
}

最佳答案

如果只希望用户能够搜索名称，请使用以下命令：

String entered;
while(true) {
    entered = input.nextLine();
    if(entered.equalsIgnoreCase("exit")) break;
    for(int i = 0; i < nameArray.length; i++) {
        if(entered.equals(nameArray[i])) {
            System.out.println("Name: " + nameArray[i] + "\tTime: " + resultArray[i]);
        }
    }
}
