Java if or exception?

i creaded you a couple of examples - mabye you like some of them. my personal opinion is to use exceptions as less as possible cause they interrupt your control flow very exceptional and maybe very unexcepted, they have to be catched (could be tricky on runtime exceptions - cause you have to know the code you are calling - which is not information hiding)and try catch blocks are very ugly compared to a simple if statement :-) but to the code:

private boolean confirmFirstName(String firstName) {
    System.out.println("You wrote "
            + firstName
            + " is that correct? \n"
            + "Y or N");
    final String answer = sc.next().toUpperCase();
    return answer.equalsIgnoreCase("y");
}

private String enterFirstName() {
    System.out.println("Please enter Client's first name");
    final String sFirstName = sc.nextLine().toUpperCase();
    return sFirstName;
}

private void getFirstNameV1() {
    final int maxTrials = 5;
    // loop for max trials times and break if input is correct
    for (int i = 0; i < maxTrials; i++) {
        final String firstName = enterFirstName();
        if (confirmFirstName(firstName)) {
            setMonthlyRates(firstName);
            break;
        }
    }
}

private void getFirstNameV2() {
    final String firstName = enterFirstName();
    final boolean valid = confirmFirstName(firstName);
    // use a recursive function but take care,
    // there is no exit instead of entering a valid value otherwise you are in an infinite loop
    if (valid) {
        setMonthlyRates(firstName);
    } else {
        getFirstNameV2();
    }
}

private void getFirstNameV3() {
    // first time input
    String firstName = enterFirstName();
    boolean valid = confirmFirstName(firstName);
    // if not valid loop until its valid, there is also no exit of this loop
    while (!valid) {
        firstName = enterFirstName();
        valid = confirmFirstName(firstName);
    }
    setMonthlyRates(firstName);
}

private void getFirstNameV4() {
    // first time input
    String firstName = enterFirstName();
    boolean valid = confirmFirstName(firstName);
    final int maxTrials = 5;
    // if not valid loop for max trials times
    for (int i = 0; i < maxTrials || valid; i++) {
        firstName = enterFirstName();
        valid = confirmFirstName(firstName);
    }
    if (valid) {
        setMonthlyRates(firstName);
    }
}

private void setMonthlyRates(String firstName) {
    monthlyRates.setFirstName(firstName);
}
