{219}  lines 13 and 14 of monthlyPayment(...) method

The corrected version follows:

// Compute monthly interest payments on a loan
public static BigDecimal monthlyPayment(int amount, // amount of loan
					int years,  // term in years
					double apr) // annual interest %
{
    // BigDecimal can compute arbitrary precision results.
    // But this causes problems with repeating decimals on division,
    // and can take a long time for exponentiation.  So we use a 
    // MathContext to specify how much precision we want
    MathContext c = MathContext.DECIMAL128;

    // Convert the loan amount to a BigDecimal
    BigDecimal principal = new BigDecimal(amount);

    // Convert term of loan in years to number of monthly payments
    int payments=years*12;

    // Convert interest from annual percent to a monthly decimal
    BigDecimal interest = BigDecimal.valueOf(apr); 
    interest = interest.divide(new BigDecimal(100));     // as fraction
    interest = interest.divide(new BigDecimal(12), c);   // monthly

    // The monthly payment computation
    BigDecimal x = interest.add(BigDecimal.ONE).pow(payments, c);

    BigDecimal y = principal.multiply(interest).multiply(x);
    BigDecimal monthly = y.divide(x.subtract(BigDecimal.ONE), c);

    // Convert to two decimal places
    monthly = monthly.setScale(2, RoundingMode.HALF_EVEN); 

    return monthly;
