我试图在Java中获取abject数组的用户输入。但是它不能正常工作。我创建了第一类并声明了所有属性，创建了构造函数、geter和seters。但是当我在数组中保存服从对象时，它不能正常工作

import java.util.Scanner;

public class Account
{
    private String HolderName;
    private int AccNom;
    private String Type;
    private double CurrentBalance;


    public Account(){
        this.HolderName="Name";
        this.AccNom= 0000;
        this.Type="Account";
        this.CurrentBalance=0.00;
    }
    public Account(String name,int AccNumber, String acctype, double balance ){
        this.HolderName = name;
        this.AccNom = AccNumber;
        this.Type = acctype;
        this.CurrentBalance = balance;
    }
    public String getHolderName(){
        return HolderName;
    }
    public int getAccNom(){
        return AccNom;
    }
    public String getType(){
        return Type;
    }
    public double getCurrentBalance(){
        return CurrentBalance;
    }
    public void setHolderName(String FirstName){
        this.HolderName=FirstName;
        FirstName = this.HolderName;
    }
    public void setAccNom(int number){
        this.AccNom = number;
        number = this.AccNom;


    }
    public void setType(String acc){
        this.Type = acc;
        acc = this.Type;
    }
    public void setCurrentBalance(double Balance){
        this.CurrentBalance = Balance;
        Balance = this.CurrentBalance;
    }
    public void depostMoney(double amount){
        if (amount>0){
            this.CurrentBalance += amount;
        }else {
            System.out.println("Invalid amount");
        }
    }
    public void withdrawMoney(double amount){

        if (amount<this.CurrentBalance){
            this.CurrentBalance -= amount;
        }else {
            System.out.println("Sorry insufficient Account Balance");
        }
    }
    public void ViewDetails(){
        System.out.println("Name: "+ this.HolderName+"\nAccount Number: " + this.AccNom + "\nAccount Type: " + this.Type + "\nBalance: " + this.getCurrentBalance() );
    }
    public double checkBalance(double balance){
        System.out.println("Current Balance: "+this.CurrentBalance);
        return balance;
    }

}



    import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Account[] acc  = new Account[4];
        for (int i = 0;i< acc.length;i++){
            acc[i] = new Account();
        }
        while (true) {
            AddCustomer(acc);
            for (int i = 0; i < acc.length; i++) {

                    acc[i].ViewDetails();




            }
        }
        }
    public static void AddCustomer(Account[] acc){
        Scanner x = new Scanner(System.in);
        for (int i = 0;i< acc.length;i++){
                acc[i] = new Account();
                System.out.println("User's Name:");
                String name = x.nextLine();
                System.out.println("Account Number: ");
                int AccountNumber = x.nextInt();
                System.out.println("Account Type: ");
                String AccType = x.next();
                System.out.println("Enter the Current Balance: ");
                double CurrentBalance = x.nextDouble();
                System.out.println("Your Account has been Created");
                acc[i] = new Account(name, AccountNumber, AccType, CurrentBalance);

        }
    }
}

从我看到的情况来看，您正在使用for循环添加一个新帐户，方法是将其放置在数组的最后一个元素。然而，您没有办法打破for循环。您可能想要尝试添加中断 添加到您的AddCustomer代码和您的ViewDetails（）下面 主
