Boolean help
Hey, I'm stuck on my current code, interest calculator, to solve for simple, monthly compounded, and daily compounded interest.
If one error occurs I need it to state the error, if two errors occur I need it to state them both, and so on..
Right now if I have an error on any of them my last error is the one that pops up.. Any help would be great!!
Code java:

```import java.util.Scanner; public class InterestCalculator2{ public static void main(String[] args ) { Scanner input = new Scanner(System.in);   //Prompt user to enter loan amount System.out.print("Enter Loan Amount: "); int principle = input.nextInt();   //Prompt user to enter interest rate System.out.print("Enter Yearly Interest Rate (1 to 100 percent): "); double interest = input.nextDouble();   //Prompt user to enter term System.out.print("Enter the Term (in months): "); int term = input.nextInt();       double simple= principle*(interest/100.0)*(term/12.0); double repaidSimple= simple+principle; double a = 1.0+((interest/100)/365.0); double b = (365*(term/12.0)); double daily = Math.pow(a,b); double dailyCompound = (principle*daily)-principle; double repaidDaily = dailyCompound + principle; double c = 1.0+((interest/100)/12.0); double d = (12*(term/12.0)); double monthly = Math.pow(c, d); double monthlyCompound = (principle*monthly)-principle; double repaidMonthly = monthlyCompound + principle; int type = 0;   if (principle > 0) { if (interest > 0 && interest < 100) { if(term > 0) { switch(type) { case 1: break;   case 2: break;   case 3: break;   default: break; } } else { System.out.println("Data Error: Interest rate must be greater than or equal to zero and less than or equal to 100. You entered " +interest); } } else { System.out.println("Data Error: Loan amount must be greater than zero. You entered " +principle); } } else { System.out.println("Data Error: Term must be greater than zero. You entered " +term); }     //Prompt user to enter calculation type System.out.print("Enter Interest Calculation Type (1 – Simple, 2 – Monthly Compounded, 3 – Daily Compounded):"); type = input.nextInt();     switch(type) { case 1:System.out.println("Total calculated interest: " +simple); System.out.println("Total amount to be repaid: " +repaidSimple); break; case 2:Sprintln("Total calculated interest: " +monthlyCompound); System.out.println("Total amount to be repaid: " +repaidMonthly); break; case 3:System.out.println("Total calculated interest: " +dailyCompound); System.out.println("Total amount to be repaid: " +repaidDaily); break; default: System.out.println("Calculation Type Error: You must select 1, 2 or 3. You entered " +type); break; } }   }```

Here is the output I get
Enter Loan Amount: 0
Enter Yearly Interest Rate (1 to 100 percent): 100.1
Enter the Term (in months): 12
Data Error: Term must be greater than zero. You entered 12
Enter Interest Calculation Type (1 – Simple, 2 – Monthly Compounded, 3 – Daily Compounded):

As you can see thats the wrong error I need to be outputted and I cant figure out how to keep it from asking "Enter Interest Calculation Type (1 – Simple, 2 – Monthly Compounded, 3 – Daily Compounded):" when an error has occured!

This is how the output should look:
Enter loan amount: 0
Enter yearly interest rate (0 to 100 percent): 100.1
Enter the term (in months): 12
Data Error: Loan amount must be greater than zero. You entered '0'.
Data Error: Interest rate must be greater than or equal to zero and less than or equal to 100.
You entered '100.1'.

Thanks for the help!
