Java-将数组的元素与传递的int进行比较以查看是否相同时，if语句失败

问题描述

这里有些困惑。我设置的方式在被调用时，应该循环遍历所填充数组的每个元素，并检查该元素的int accNum是否等于传递的int accNum，如果是，则输出帐户摘要。

也许我的逻辑是错误的，但在我看来应该可行：

public void accountInfo(int accNum)
    {
        for (int i = 0; i < numAccounts; i++)
        {
            if (accNum == accounts[i].getAccNum())
            {
                accounts[i].summary();
            }
            else
            {
                System.out.println("No such account on record.");
            }
        }
    }

帐户类别：

public class Account
{
    private String ssn;
    private int accNum,accType;
    private double balance;
    private Customer accountHolder;

    public Account(Customer accountHolder,String ssn,int accNum,int accType,double balance)
    {
        this.accountHolder = accountHolder;
        this.ssn = ssn;
        this.accNum = accNum;
        this.accType = accType;
        this.balance = balance;
    }

    public String summary()
    {
        String fullType;
        switch (accType)
        {
            case 1:
                fullType = "Checking";
                break;
            case 2:
                fullType = "Savings";
                break;
            default:
                fullType = "Other";
        }

        return String.format(("\t- Number: %d\n\t- %s\n\t- Balance: $%.2f\n\t- Customer: %s"),accNum,fullType,balance,accountHolder.getName());
    }

    public double getBalance()
    {
        return balance;
    }

    public int getAccNum()
    {
        return accNum;
    }

    public void deposit(double balance)
    {
        this.balance += balance;
    }

    public void withdraw(double balance)
    {
        this.balance -= balance;
    }

}

/*Note that an Account object can have only one Customer.
 */

我的输出：
