public String toString(){
String retString;
retString = "customerName : "+this.getCustomerName()+" AccountNumber : "+this.getAccountNumber()+" Balance : "+this.getBalance();
return retString;   
}
}

sketch an .toSting() method to overide the default print output.

Explanation / Answer

You already have got the toString method defined for your derived class...


public String toString(){
String retString;
retString = "customerName : "+this.getCustomerName()+" AccountNumber : "+this.getAccountNumber()+" Balance : "+this.getBalance();
return retString;   
}

It will override the toString method defined in JavaAccount class.. you have not provided the code for JavaAccount class otherwise i would have shown you the output by executing the code.

Let me know in comments if you face any issues and i will surely help you. FOr the current code which you provided, it is absolutely fine.
