I am not sure if I am doing this correctly since it has been awhile since I last used Daniweb. I need some help with the code that I have submitted and am getting the following two errors. I am new to java and not sure of what to do. Can someone please help me to get my code to compile and run as expected?

```
/*Program: MortgagePaymentCalculatorCR3.java
Purpose: To write a Java program (without GUI) for agents of McBride Financial
Services. This resource will calculate and display the payment expected
for 3 mortgage loans with the following terms and interest rates using
an array:
7 year @ 5.35%
15 year @ 5.5%
30 year @ 5.75%
The loan balance and interest paid for each payment over the duration of
each loan will also be displayed. Loops will display part of the list,
pause, and display more of the list to the agent.
