I'm working on a program (with a graphical user interface) that will calculate and display the mortgage payment amount, the loan balance, loan payment number, and interest paid from each payment from these three loans below:

7 years at 5.35%

15 years at 5.5%

30 years at 5.75%

The problem that I'm having when I compile my code I'm getting these three errors:

orphaned case line 52

orphaned case line 79

orphaned default line 106

Here is my source code:

import java.text.DecimalFormat;

double monthlyPayment;//Declaring my Variables

int loanAmount;

double loanInterest;

DecimalFormat decimalPlaces=new DecimalFormat("0.00"); //Format decimal point for proper display

totalLoan=JOptionPane.showInputDialog(null, "Enter the number of What Loan You would like to see broken down by\n mortgage payment amount followed by the loan balance and interest paid for each payment:\n 1. 7 years at 5.35%:\n 2. 15 years at 5.5%:\n 3. 30 years at 5.75%\n ");

I have bolded the source code that has errors. Any help on this would be much appreciated.
