Java 将多个输入值存储到单个数组元素

Question

我想将所有输入值传递给数组中的一个元素。我尝试过使用数组，但不太了解它们如何处理多个输入值。 p>

我读过 Oracle 和这里​​的内容，但没有什么真正突出的，或者他们诉诸数组列表。

有没有办法封装这些值，然后将它们存储到数组中？

非常感谢任何帮助。

import java.util.Scanner;

class Mobile
{
 private String name;  
 private int number;
 private int quantity;
 private double cost;

 public Mobile(String name, int number, int quantity, double cost)
 {
  this.name = name;
  this.number = number;
  this.quantity = quantity;
  this.cost = cost;
 }
 public String getName()
 {
  return name;
 }
 public void setName(String name)
 {
  this.name = name;
 }
 public int getNumber()
 {
  return number;
 }
 public void setNumber(int number)
 {
  this.number = number;
 }
 public int getQuantity()
 {
  return quantity;
 }
 public void setQuantity(int quantity)
 {
  this.quantity = quantity;
 }
 public double getCost()
 {
  return cost;
 }
 public void setCost(double cost)
 {
  this.cost = cost;
 }
 public double getValue()
 {
  return cost*quantity;
 }
}

public class MobilePhone
{
 public static void main (String args[])
 {
  String itemName;
  int itemNum;
  int itemQuan;
  double unitCost;

  for(int i=0;i<5;i++)
  {
   Scanner input = new Scanner(System.in);

   System.out.print("Enter Item Name: ");
   itemName = input.nextLine();

   System.out.print("Enter Item Number: ");
   itemNum = input.nextInt();         

   System.out.print("Enter Quantity of Item: ");
   itemQuan = input.nextInt();

   System.out.print("Enter Price of Single Unit: ");
   unitCost = input.nextDouble();

   Mobile m = new Mobile(itemName, itemNum, itemQuan, unitCost);
  }
 }
}

我的理解是，您希望将手机放入长度为 5 的数组中，每个输入的手机对应一个数组。因此，您可以声明一个数组 Mobile mobileValues[] = new Mobile[5];，并在收集数据后将每个值放入数组中 mobileValues[i] = new Mobile(itemName, itemNum、itemQuan、unitCost);

public static void main (String args[])
{
  String itemName;
  int itemNum;
  int itemQuan;
  double unitCost;
  Mobile mobileValues[] = new Mobile[5];

  for(int i=0;i<5;i++)
  {
      Scanner input = new Scanner(System.in);
      System.out.print("Enter Item Name: ");
      itemName = input.nextLine();
      System.out.print("Enter Item Number: ");
      itemNum = input.nextInt();         
      System.out.print("Enter Quantity of Item: ");
      itemQuan = input.nextInt();

      System.out.print("Enter Price of Single Unit: ");
      unitCost = input.nextDouble();

      mobileValues[i] = new Mobile(itemName, itemNum, itemQuan, unitCost);
  }
}
