I'm a newbie in this java and I just started classes, they sent us this exercise:
Exercise 3
Design a class called Reloj with the integer attributes: hora (24 hours), minuto and segundo , and the following methods:
A constructor that initializes the attributes to values passed as parameters.
A method called Increase that increases the time in a second.
For example:
17:53:59 will be 17:54:00
17:59:59 will be 18:00:00
4.A method called Decrement that decreases the time in a second.
For example:
17:53:00 will be 17:52:59
17:00:00 will be 16:59:59
5.A method called Hora12 that converts to String the time by concatenating its attributes and returns the string with the format of 12 hours ( hh:mm:ss AM/PM )
AM: (until 12 noon), PM (from 12 to 24 hours)
This is my code, Class Reloj :
public class Reloj {
int modo,hora, minutos,segundos;
int getmodo(){
return modo;
}
public void setmodo(int modo){
this.modo=modo;
}
int gethora(){
return hora;
}
public void sethora(int hora){
this.hora=hora;
}
public int getminutos(){
return minutos;
}
public void setminutos(int minutos){
this.minutos=minutos;
}
public int getsegundos(){
return segundos;
}
public void setsegundos(int segundos){
this.segundos=segundos;
}
public Reloj(){
modo=24; /*por defecto ponemos 24horas*/
hora=0;
minutos=0;
segundos=0;
}
public Reloj( int h, int m, int s){
this.modo=24;
this.hora=h %24;
this.minutos=m % 60;
this.segundos=s % 60;
}
public void ponerEnHora(int md, int hh, int mm, int ss){
modo=md;
hora=hh % 24;
minutos=mm % 60;
segundos=ss % 60;
}
public void incrementar(){
segundos++;
if (segundos==60){
segundos=0;
minutos++;
if(minutos==60){
minutos=0;
hora=(hora+1)%24;
}
}
}
public void decrementa(){
segundos--;
if(segundos<00){
segundos=59;
minutos--;
if(minutos<00){
minutos=59;
hora=(hora-1) %24;
}
}
}
public String verHora(){
String hms="Son las ";
if (modo==12){//modo 12 horas
hms+=(hora>12)?hora-12:hora;
hms+= ":"+minutos+":"+segundos;
hms+=(hora>=12)?"pm":"am";
}else{//modo 24h
hms+=hora+":"+minutos+":"+segundos;
}
return (hms);
}
}
MAIN watches class:
public class Relojes {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Reloj reloj1 = new Reloj();
reloj1.ponerEnHora(24,17,10,10);
System.out.println(reloj1.verHora());
reloj1.incrementar();
System.out.println(reloj1.verHora());
reloj1.decrementa();
System.out.println(reloj1.verHora());
}
}
I do not get the hours in 12H mode, everything else works, but that I print the 12h mode with AM or PM does not come out, to see if you can help me out.
