本文介紹了如何將一個(gè)數(shù)組輸入與另一個(gè)數(shù)組輸入相關(guān)聯(lián)？的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！

問(wèn)題描述

假設(shè)我有2個(gè)掃描儀填充的數(shù)組，name[]和age[]。每一張都是按順序填寫(xiě)的。如果我要查找數(shù)組中年齡最大的人，我如何使用數(shù)組打印出他們的姓名和年齡？
例如，age[]中最大的條目是78。有沒(méi)有辦法將其與name[]數(shù)組關(guān)聯(lián)以將其打印出來(lái)？

參考編碼：

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.println("How many entries ?");

    int entries;
    do {
        entries = input.nextInt();
        if (entries < 1) {
            System.out.println("please enter a valid number!");
        }
    } while (entries < 1);

    String[] name = new String[entries];
    String[] gender = new String[entries];
    int[] age = new int[entries];

    for (int i = 0; i < entries; i++) {
        System.out.println("Enter the name of person No" + (i + 1) + ".");
        name[i] = input.next();
    }

    double ageSum = 0;
    int max = 0;
    for (int i = 0; i < entries; i++) {
        System.out.println("How old is " + name[i] + " ?");
        age[i] = input.nextInt();
        ageSum += age[i];
        max = Math.max(max, age[i]);
    }

    System.out.println("the oldest person is "
            + name[] + " whose " + max + " years old.");
}

推薦答案

假設(shè)您的數(shù)組具有相同的大小和與名稱(chēng)對(duì)應(yīng)的期限，那么您可以檢查最高期限并存儲(chǔ)具有最高期限的元素的索引。

那么您的名字就在這個(gè)指示符上。

int highestAgeIndice = 3; //indice of element with age 97 as example

names[highestAgeIndice] // the corresponding name

計(jì)算最高年齡并存儲(chǔ)其索引

int max = 0;
int highestInd = 0;
for (int i = 0; i < age.length; i++) {
    if (age[i] > max) {
        max = age[i];
        highestInd = i;
    }
}

System.out.println("the oldest person is " +
        name[highestInd] + " whose " + max + " years old.");

代碼

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.println("How many entries ?");

    int entries;
    do {
        entries = input.nextInt();
        if (entries < 1) {
            System.out.println("please enter a valid number!");
        }
    } while (entries < 1);

    String[] name = new String[entries];
    String[] gender = new String[entries];
    int[] age = new int[entries];

    for (int i = 0; i < entries; i++) {
        System.out.println("Enter the name of person No" + (i + 1) + ".");
        name[i] = input.next();
    }

    double ageSum = 0;
    for (int i = 0; i < entries; i++) {
        System.out.println("How old is " + name[i] + " ?");
        age[i] = input.nextInt();
        ageSum += age[i];
    }

    int max = 0;
    int highestInd = 0;
    for (int i = 0; i < age.length; i++) {
        if (age[i] > max) {
            max = age[i];
            highestInd = i;
        }
    }
    System.out.println("the oldest person is " +
            name[highestInd] + " whose " + max + " years old.");
}
