OverLimit Exception handling in java

Question

Program to raise an exception stating "Further Transactions Not Possible until clearance of bill." when a customer's unpaid credit card amount cross $2000 or is unpaid upto 45 days. Assume that the current date is 01/12/2015.

Create a custom exception class OverLimitException which extends Exception.
Add a constructor which takes a Throwable object, calls the super class constructor using super() and prints the output as described in the problem statement.

I created two classes one main and the other account

Account.java

import java.text.*;
import java.util.*;
import java.util.concurrent.TimeUnit;

public class Account {

String accountNumber;
String accountName;
Double dueAmount;

public Account(String accountNumber, String accountName,Double dueAmount) throws ParseException {
    this.accountNumber = accountNumber;
    this.accountName = accountName;
    this.dueAmount = dueAmount;
}

public Account() {
}

public Boolean validate(String dueDate,Double unpaid,Double amount){
    DateFormat sf = new SimpleDateFormat("dd/MM/yyyy");
    sf.setLenient(false);
    try{
        Date d = sf.parse(dueDate);
        Date d1 = sf.parse("01/12/2015");
       // long curDate = new Date().getTime();
        long diff =d1.getTime() - d.getTime();
        long daysDiff = TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS);
        if(daysDiff > 45 || unpaid > 2000){
            throw new OverLimitException("Further Transactions Not Possible until clearance of bill.");
        }
    }catch(Exception e){
        return false;
    }
    return true;
}

public void display() {       
    System.out.println("Transaction successsfully completed.");
    System.out.println("Account Number : "+this.accountNumber);
    System.out.println("Account Name : "+this.accountName);
    System.out.println("Unpaid Amount : "+this.dueAmount);
}
}

But am getting an error stating

 error: cannot find symbol
 throw new OverLimitException("Further Transactions Not Possible until clearance of bill.");
 ^
 symbol: class OverLimitException

Can any one please help me solve this problem?

And hint: you don't want to return **B**oolean, but **b**oolean. — GhostCat, Aug 26 '16 at 14:21

OverLimitException is not an exception that comes with Java.

Like the other classes you created, you have to write that class, too; like:

public class OverLimitException extends RuntimeException {

and provide a constructor that takes a message string for example.

The valiade function has to throw OverLimitException and you have to define it

public Boolean validate(String dueDate,Double unpaid,Double amount) 
      throws OverLimitException{
      ...
      if(daysDiff > 45 || unpaid > 2000){
          throw new OverLimitException("Further Transactions Not Possible  until clearance of bill.");
    }
    ...

}

and implement the OverLimitException ; here is an example

     public class OverLimitException extends Exception {
         public OverLimitException(String message) {
            super(message);
         }
     }
