Exception Handling

This refers to the method of catching and handling an exception object (Exception) that has been thrown.

1. When the program must proceed regardless of the processing result of a certain business logic

try {
    ...
} catch (DefaultApplicationException e) {
    // Handle
}

The exception is caught and then thrown again. When creating a new Exception, pass the caught Exception as a parameter.

try {
    ...
} catch (DefaultApplicationException e) {
    throw new DefaultApplicationException("BXME30007", null, e);
}

try {
    ...
} catch (DasDuplicateKeyException e) {
    throw new DefaultApplicationException("BXME30011", new Object[] {empNo}, e);
}
