How do you stop a program from running in a blueprint class using a nested if statement and not a System.exit(0);?

Question

In this code I tried to stop the program from running by using System.exit(0);

Is there a possible way to exit the program using a nested if statement and not using System.exit(0);

public String answerR1()
{
    if (answer .equals ("snow"))
    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        System.exit(0);
    }
    return message;
}
public String answerR2()
{
    answer = answer.toLowerCase();
    if (answer .equals ("time"))
    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        System.exit(0);
    }
    return message;
}
public String answerR3()
{
    if (answers == 20)
    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        System.exit(0);
    }
    return message;
}

@GeorgeZ. How much uncertainty is there when it comes to exiting a program? — TylerH, Mar 17 '19 at 22:37
@TylerH For some reason i think he just wants to "interrupt" method's flow, returning "" value or something. — George Z., Mar 17 '19 at 22:39
@GeorgeZ. I haven't written Java since 9th grade so I have no clue; it seems clear though that OP is asking for ways other than System.exit(0) to exit his program. — TylerH, Mar 17 '19 at 22:40

If you truly intend to exit the program, then there's nothing wrong with `System.exit(0)`. Why are you seeking an alternative? — Dawood ibn Kareem, Mar 17 '19 at 23:20

    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        //System.exit(0);
        break;
    }
    return message;
}
public String answerR2()
{
    answer = answer.toLowerCase();
    if (answer .equals ("time"))
    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        //System.exit(0);
        break;
    }
    return message;
}
public String answerR3()
{
    if (answers == 20)
    {
        message = "\nCorrect!";
    }
    else
    {
        message = "\nIncorrect!";
        //System.exit(0);
        break;
    }
    return message;
}

Try to use Break instead of System.exit(0);

Did you test this? – Dawood ibn Kareem Mar 17 '19 at 23:10 — Dawood ibn Kareem, Mar 17 '19 at 23:10
