Ich entwickle kleine AOP Standalone-Projekt dort, wenn ich meine eigene Ausnahme erstellen, geben Sie diese Fehler Ausnahme inkompatibel mit throws clause.please, wenn jemand helfen kann sehr schätzen.Exception inkompatibel mit throws-Klausel
Dies ist die Exception-Klasse i
geschrieben wurdepackage com.mtit.exceptions;
public class InsufficientAmountException extends Exception
{
/**
* exception for handling invalid payment
*/
private static final long serialVersionUID = 1L;
public InsufficientAmountException(String message)
{
super(message);
}
}
Dies ist die Methode
public void PaymentPatient(String PatientID,double discountRate,double ChargePerDay,double cashAmount) throws InsufficientAmountException
{
double totalAmount=CalculateTotalAmountPatient(PatientID,discountRate,ChargePerDay);
if(cashAmount>=totalAmount)
{
double balance=cashAmount-totalAmount;
System.out.println("Payment Succefully done your balance is "+"\t"+balance);
}
else
{
throw new InsufficientAmountException("Balance is insufficient");
}
}
Hier ist die wichtigste Methode
try
{
//call the payment method i have written above
}
catch(InsufficientAmountException e)
{
System.out.println("");
}
main-Methode
public class Main {
public static void main(String[] args)
{
try
{
Payment();
}
catch(InsufficientAmountException e)
{
System.out.println("");
}
}
public static void Payment()
{
PatientService patientService=new PatientServiceImpl();
Scanner scanner=new Scanner(System.in);
System.out.println("Enter Patient ID");
String id=scanner.nextLine();
System.out.println("Enter Discount rate");
double discount=Double.parseDouble(scanner.nextLine());
System.out.println("Enter No of Days");
int noOfDays=Integer.parseInt(scanner.nextLine());
double totalAmount=patientService.CalculateTotalAmountPatient(id, discount, noOfDays);
System.out.println("Your total charge is"+"\t"+totalAmount);
System.out.println("Would you like to do payment enter yes or no");
String result=scanner.nextLine();
if(result=="yes")
{
System.out.println("Enter charge per day");
double ChargePerDay=Double.parseDouble(scanner.nextLine());
System.out.println("Enter cash amount");
double cashAmount=Double.parseDouble(scanner.nextLine());
patientService.PaymentPatient(id, discount, ChargePerDay, cashAmount);
}
else
{
System.out.println("Please do the payment with in 3 days to get rid from tax");
}
}
