Thread: 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!!

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!
