Question

要求是获取航空公司的用户输入及其费率。然后我们必须显示基于航空公司费率排序的组合阵列。

例如：以下条目是数组形式的用户输入，其数量和描述可根据用户的需要而变化。输入数组将合并并进行排序

输入承运人列表：

Air India
Lufthansa
Emirates
Etihad
British Airways

输入费用：

输出：

Lufthansa-350
Emirates-400
British Airways-450
Air India-500
Emirates-550

即组合阵列将根据运营商的成本进行分类。我的代码：

import java.util.Scanner;
public class Main {
    public static void main(String args[]){

        // fill the code
        int n,i,temp;
        Scanner sc = new Scanner(System.in);
        n = sc.nextInt();
        int a[] = new int[n];
        String b[] = new String[n]; 
        for (i=0;i<n;i++)
        {
            b[i] = sc.next();
        }
        for (i=0;i<n;i++)
        {
          a[i] = sc.nextInt();  
        }
        for (i=0;i<n;i++)
        {

        System.out.println("Details are :"+(b[i]+"-"+a[i]));
      }
       for ( i = 0; i < n; i++) 
        {
            for (int j = i + 1; j < n; j++) 
            {
                if ((a[i]) > (a[j]))
                {
                    temp = (a[i]);
                    (a[i]) = (a[j]);
                    (a[j]) = temp;
                }
            }
        }
        System.out.println("Sorted are :"+(b[i]+"-"+a[i]));
    }
}

Answer 1

import java.util.*;

public class Mapp {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Map<Integer,String> mp=new TreeMap<>();
        mp.put(500,"Air India");
        mp.put(350,"Lufthansa");
        mp.put(400,"Emirates");
        mp.put(550,"Etihad");
        mp.put(450,"British Airways");

         Set mapset=mp.entrySet();
         System.out.println(mp);
    }

}

如果您希望用户输入值

：import java.util。*;

public class Mapp {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Map<Integer,String> mp=new TreeMap<>();
        System.out.println("Enter number of Entries: ");
        Scanner sc=new Scanner(System.in);
        int et=0;
        et=sc.nextInt();
        while(et!=0)
       {
          System.out.println("Enter Cost");
         int cost=0;
         Scanner cst=new Scanner(System.in);
         cost=cst.nextInt();
         System.out.println("Enter Airline Service");
         Scanner name=new Scanner(System.in);
         String nm=null;
         nm=name.nextLine();
         mp.put(cost,nm);
         et--;
       }


         Set mapset=mp.entrySet();
         System.out.println(mp);
    }

}

java程序根据运营商成本对航空公司进行排序
