    Default Reading lines from a txt file

    I'm having trouble with my code.
    I have a text file with the following input
    99.99 67 178843.00
    87.4 3 8983.00

    how do i read these input and store them in separate variables?
    this is the code that i have:-
    Scanner inputFile = new Scanner(myFile);
    while (inputFile.hasNext())
    {
    interest = inputFile.nextDouble();
    years = inputFile.nextInt();
    amount = inputFile.nextDouble();

    bank.setInterestRate(interest);
    bank.setYears(years);
    bank.setAmount(amount);
    System.out.println();
    System.out.println("The monthly payment is: " + money.format(bank.getMonthlyPayment()));
    System.out.println("The total payment is: " + money.format(bank.getTotalPayment()));

    }
    inputFile.close()

    I'm having trouble with my code.
    Can you explain what the problem is? What does the code do when executed?

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    <Scanner inputFile = new Scanner(myFile);
    while (inputFile.hasNext())
    {
    interest = inputFile.nextDouble();
    years = inputFile.nextInt();
    amount = inputFile.nextDouble();
     
    bank.setInterestRate(interest);
    bank.setYears(years);
    bank.setAmount(amount);
    System.out.println();
    System.out.println("The monthly payment is: " + money.format(bank.getMonthlyPayment()));
    System.out.println("The total payment is: " + money.format(bank.getTotalPayment()));
     
    }
    inputFile.close()>
    it reads numbers from the text file to calculate a loan.

    The posted code needs formatting. All statements should NOT start in the first column. Statements within {} should be indented 3-4 spaces.

    Can you explain what the problem is?
