java - 如何将年份与Java中的值for-loop相匹配？

Question

我是编程新手，所以请不要评判我。我在做一个项目，我每年都加一个分数。对于输出，它应该说最高分和它所在的年份，但我不知道如何显示与疮匹配的年份。

预期输出：

输入年数：5

输入起始年份：1999

输入 1999 年的统计数据：4

输入 2000 年的统计数据：7

输入 2001 年的统计数据：8

输入 2002 年的统计数据：10

输入 2003 年的统计数据：6

2002 年最好的统计数据是 10

1999 年最差的数据是 4

我的输出：

输入年数：5

输入起始年份：1999

输入 1999 年的统计数据：4

输入 2000 年的统计数据：7

输入 2001 年的统计数据：8

输入 2002 年的统计数据：10

输入 2003 年的统计数据：6

2004 年最好的统计数据是 10

这是我的代码

import java.util.Scanner;

public class Assignment5A {
    public static void main(String[]args){
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter the number of years: ");
        int nubyear = sc.nextInt();

        int years [] = new int[nubyear];

        int i;
        int j;
        int h;
        int startyear = 0;
        int large =years[0];
        int yearcountr=0;


        System.out.print("Enter the starting year: ");
        startyear = sc.nextInt();

        for (i=0; i<nubyear; i++){
             years[i] = startyear++;
            System.out.print("Enter stat for year "+years[i]+": ");
             years[i] = sc.nextInt();
             if (large < years[i]){
                large = years[i];
                years[i] = startyear;
             }
            }
        System.out.print("Best stat was "+large+" in year "+startyear );
        }

}

如果您不打算检索用户输入的所有值，则实际上不需要数组。您可以在用户输入每个值时对最高值进行比较。

import java.util.Scanner;

public class Assignment5A {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter the number of years: ");
        int nubyear = sc.nextInt();

        System.out.print("Enter the starting year: ");
        int startyear = sc.nextInt();

        int highYear = 0; //variable to hold the year with the highest stat
        int highStat = 0; //variable to hold the current highest stat
        
        for (int i = 0; i < nubyear; i++) { 
            int tempYear = startyear++; //Hold the current year value until the comparison is done.
            System.out.print("Enter stat for year " + tempYear + ": ");
            int tempStat = sc.nextInt(); // Hold the current year stat until the comparison is done.
            if (highStat < tempStat) { //If the value entered is higher than the previous one, save the year and stat.
                highYear = tempYear;
                highStat = tempStat;
            }
        }       
        System.out.print("Best stat was " + highStat + " in year " + highYear);
    }

}

import java.util.Scanner;

public class YearDemo {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int numOfYrs = 0, startYrs = 0,statInput = 0,count = 0;

        System.out.println("Enter the number of years: ");
        numOfYrs = sc.nextInt();
        int years[] = new int[numOfYrs];
        int stat[] = new int[numOfYrs];
        
        System.out.println("Enter the starting year: ");
        startYrs = sc.nextInt();
        
        while (numOfYrs != 0) {
            System.out.println("Enter stat for year: " + startYrs);
            statInput = sc.nextInt();
            years[count] = startYrs++;
            stat[count++] = statInput;
            numOfYrs--;
        }
        
        int largest = -(Integer.MAX_VALUE),smallest = Integer.MAX_VALUE,bestYear = 0,worstYear = 0;
        for (int i = 0; i < stat.length; i++) {
            if(largest < stat[i]) {
                largest = stat[i];
                bestYear = years[i];
            }
            if(smallest > stat[i]) {
                smallest = stat[i];
                worstYear = years[i];
            }
        }
        System.out.println("Best Year: " + largest + " in year " + bestYear);
        System.out.println("Worst Year: " + smallest + " in year " + worstYear);
    }

}

你的代码应该是这样的：

    Scanner sc = new Scanner(System.in);
    System.out.print("Enter the number of years: ");
    int nubyear = sc.nextInt();

    int years [] = new int[nubyear];

    int i;
    int j;
    int h;
    int startyear = 0;
    int large =years[0];
    int yearcountr=0;
    int largest_year = 0 ;

    System.out.print("Enter the starting year: ");
    startyear = sc.nextInt();

    for (i=0; i<nubyear; i++){
         years[i] = startyear;
        System.out.print("Enter stat for year "+years[i]+": ");
         years[i] = sc.nextInt();
         if (large < years[i]){
            large = years[i];
            largest_year = startyear ;
         }
         startyear ++ ;
        }
    System.out.print("Best stat was "+large+" in year "+largest_year );
    }

}
