所有编译都可以运行此程序,但它一直在给我这个 错误我试图一步一步地看到什么是错的,似乎无法找到它 有人请帮帮我,我把文本文件放在与程序相同的文件夹中 所以我不明白为什么它不期待文本文件
Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Scanner.java:862)
at java.util.Scanner.next(Scanner.java:1485)
at java.util.Scanner.nextDouble(Scanner.java:2413)
at Deposit.main(Deposit.java:32)
这是主程序类:
public class Deposit
{
public static void main(String[] args) throws IOException
{
SavingsAccount account1 = new SavingsAccount(500);
account1.setAnnualInterest(10);
double totalInterest = 0;
File depositFile = new File("Deposits.txt");
File withdrawlFile = new File("Withdrawls.txt");
Scanner inputFile = new Scanner(depositFile);
while(inputFile.hasNext())
{
account1.deposit(inputFile.nextDouble());
}
Scanner inputFile1 = new Scanner(withdrawlFile);
while(inputFile1.hasNext())
{
account1.withdrawl(inputFile.nextDouble());
}
inputFile.close();
inputFile1.close();
totalInterest = account1.addMonthlyInterest();
System.out.printf("Ending Balance: %f\n Total interest earned: %f" ,account1.getBalance(),totalInterest);
}
}
这是SavingAccount Class
public class SavingsAccount
{
private double annualInterest;
private double balance;
public void withdrawl(double userAmount)
{
balance += userAmount;
}
public void deposit(double userAmount)
{
balance -= userAmount;
}
public double getBalance()
{
return balance;
}
public double addMonthlyInterest()
{
double monthlyInterest = (( annualInterest / 12 ) * balance);
balance += monthlyInterest;
return monthlyInterest;
}
public void setAnnualInterest(double newRate)
{
annualInterest = newRate / 100;
}
public SavingsAccount(double startingBalance)
{
balance = startingBalance;
annualInterest = 0;
}
}
