Method that returns String and receives LocalTime

  • 772

I have a method that receives a LocalTime object, and that returns a String , the objective of this method is that when receiving a time it is for example --> 13:00 returns("It is 13 o'clock") , another example would be - -> 17:08("It is 17 and 8"). Where should I start? Passing the LocalTime object to a String?

EDIT I ​​think I've already got the answer, I'm posting it in case someone wants to know.

private static String generaTextoHora(LocalTime tiempo){

    Integer hora = tiempo.getHour();
    Integer minutos = tiempo.getMinute();
    String mensaje = "";
    if(minutos==00){
        mensaje = "son las " + hora + " en punto";
    }else if(minutos>0 && minutos <15){
        mensaje = "son las " + hora + " y " + minutos;
    }else if(minutos==15){
        mensaje = "son las " + hora +" y cuarto";
    }else if(minutos>15 && minutos>30){
        mensaje = "son las " + hora + " y " + minutos;
    }else if(minutos==30){
        mensaje = "son las" + hora + " y media";
    }else if(minutos>30 && minutos<=59){
        mensaje = "son las" + hora + " y " + minutos;
    }
    return mensaje;
}

  1. As always, refer to the documentation for the class you want to use.

    LocalTime

    There you will see methods like getHour(), getMinute(), orgetSecond()

    You will then be able to return a String based on those fields. Something like:

    public String getLocalTimeMessage(LocalTime localTime) {
    int hour = localTime.getHour();
    int minute = localTime.getMinute();

    String message = "Son las ";
    message += hour;

    if (minute == 0) {
        message += " en punto";
    } else {
        message += " y " + minute;
    }

    return message;
}

  2. A String should never be equalized using == since it is an object .equals() should be used to compare. @lois6b

    Use the toString() method which will convert it to a string like:
    - "HH:MM"
    - "HH:MM:SS"
    - ...
    - "HH:MM:SS.999999999"

    Then you can separate with a split(:");

    public string mensajeHora(LocalTime tiempo){

    String[] mensaje = tiempo.toString().split(":");
    String hora  = mensaje[0];
    String minutos = mensaje[1];
    String mensajeTexto = "";

    if(minutos == "00"){

        mensajeTexto = "Son las " + hora + " en punto");
    }else{
        mensajeTexto = "Son las " + hora + " y "+ minutos);

    }

    return mensajeTexto;

}
