Question

In the below lines of code ,I am calling validatePersonDTO method inside a while loop.I need to return back to while loop to process next record if any error occurs within validatePersonDTO’s methods for the current record.

Note:

ValidatepersonDTo method is in another class from where the while loop exists.

This is a very basic question , i have tried out some options , but neither continue or return wouldn’t work.

So kindly let me know of your suggestions.

while ((nextLine = reader.readNext()) != null) {
hrUploadValidator.validatePersonDTO(personDTO);
}

public void validatePersonDTO(PersonDTO personDTO) {
    try {           
        validateCdsId(personDTO, logDTO,regionIdList);          
        validateEmpFirstName(personDTO, logDTO);            
        validateEmpLastName(personDTO, logDTO);         
        validateEffectiveIn(personDTO, logDTO);
}

Answer 1

Assuming that validatePersonDTO throws an exception when validation fails (it’s the only option, since the method is void), you are missing a try/catch block inside your while loop:

while ((nextLine = reader.readNext()) != null) {
    try {
        hrUploadValidator.validatePersonDTO(personDTO);
    } catch (Exception ex) {
        // Log / otherwise process your exception here
    }
}

Once the exception is logged or otherwise processed in the catch block, your loop will continue its iterations from where it left off.
