Thread: Array month/day/hour/min/sec incomplete java code

Hello all, I was asked by a friend of mine to help him out with a program he needs completed, unlucky for him I have not much experience with it myself.

Wondering how the complete code would look like, or perhaps an easier way to write the whole code for this program.
The idea is that the user inputs x number of months/days/hours/minutes/seconds... and a final array will display all this information in the proper format.

Meaning:
max sec display would be 59 seconds.
Max min display would be 59 minutes.
Max hour display would be 23 hours.
Max day display would be 29 (always assuming every month has 30 days).
Max month display would be 11. If it all happens to exceed the 11 months, then the corresponding number of years would be shown in the array as well.

So here is the code:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.StringTokenizer;
public class arreglohras {
 
    private String fecha;
    private int anio;
    private int mes;
    private int dia;
    private int hora;
    private int min;
    private int seg;
 
 
    public String getFecha() {
        return fecha;
    }
    public void setFecha(String fecha) {
        this.fecha = fecha;
    }
    public int getAnio() {
        return anio;
    }
    public void setAnio(int anio) {
        this.anio = anio;
    }
    public int getMes() {
        return mes;
    }
    public void setMes(int mes) {
        this.mes = mes;
    }
    public int getDia() {
        return dia;
    }
    public void setDia(int dia) {
        this.dia = dia;
    }
    public int getHora() {
        return hora;
    }
    public void setHora(int hora) {
        this.hora = hora;
    }
    public int getMin() {
        return min;
    }
    public void setMin(int min) {
        this.min = min;
    }
    public int getSeg() {
        return seg;
    }
    public void setSeg(int seg) {
        this.seg = seg;
    }
    public static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
 
    public static void main(String[] arg) throws Exception {
 
        arreglo cal1 = new arreglo();
        arreglo cal2 = new arreglo();
        arreglo cal3 = new arreglo();
 
        System.out.println("Introduce seg:min:horas:dias:meses");
        cal1.setFecha(in.readLine());
 
        System.out.println("Introduce seg:min:horas:dias:meses");
        cal2.setFecha(in.readLine());
 
        StringTokenizer token;
 
        token = new StringTokenizer(cal1.getFecha(), ":");
 
        String uno = token.nextToken();
        int numero = Integer.parseInt(uno);
        cal1.setSeg(numero);
 
        cal1.setMin(Integer.parseInt(token.nextToken()));
        cal1.setHora(Integer.parseInt(token.nextToken()));
        cal1.setDia(Integer.parseInt(token.nextToken()));
        cal1.setMes(Integer.parseInt(token.nextToken()));
 
        token = new StringTokenizer(cal2.getFecha(), ":");
 
        cal2.setSeg(Integer.parseInt(token.nextToken()));
        cal2.setMin(Integer.parseInt(token.nextToken()));
        cal2.setHora(Integer.parseInt(token.nextToken()));
        cal2.setDia(Integer.parseInt(token.nextToken()));
        cal2.setMes(Integer.parseInt(token.nextToken()));
 
        cal3.setSeg(cal1.getSeg() + cal2.getSeg());
        cal3.setMin(cal1.getMin() + cal2.getMin() + cal3.getSeg() / 60);
        cal3.setHora(cal1.getHora() + cal2.getHora() + cal3.getMin() / 60);
        cal3.setDia(cal1.getDia() + cal2.getDia() + cal3.getHora() / 24);
        cal3.setMes(cal1.getMes() + cal2.getMes() + cal3.getDia() / 30);
        cal3.setAnio(cal3.getMes() / 12);
 
        cal3.setSeg(cal3.getSeg() % 60);
        cal3.setMin(cal3.getMin() % 60);
        cal3.setHora(cal3.getHora() % 24);
        cal3.setDia(cal3.getDia() % 30);
        cal3.setMes(cal3.getMes() % 12);
 
        System.out.println("La fecha es:");
        System.out.println(cal3.getAnio() + " Años ");
        System.out.println(cal3.getMes() + " Meses ");
        System.out.println(cal3.getDia() + " Dias ");
        System.out.println(cal3.getHora() + " Horas ");
        System.out.println(cal3.getMin() + " Minutos ");
        System.out.println(cal3.getSeg() + " Segundos ");
 
 
    }
 
}

Here is the error message when compiling:

Ok based on the fact I practically didn't understand most of the code in the other program, I've decided to start a new one.

Here is the code I have done so far:

import java.io.*;
public class apples {
		public static void main(String[] args) throws IOException{
		BufferedReader in=new BufferedReader(new InputStreamReader (System.in));
 
		int array[]=new int[6];
 
		int year,month,day,hr,min,sec;
		int a,m,d,h,mn,s;
		String year1,month1,day1,hr1,min1,sec1;
 
/*		StringTokenizer token;
		token=new StringTokenizer(date,":");
		int cad1=Integer.parseInt(token.nextToken());
		int cad2=Integer.parseInt(token.nextToken());
		int cad3=Integer.parseInt(token.nextToken());
		int cad4=Integer.parseInt(token.nextToken());
		int cad5=Integer.parseInt(token.nextToken());
		int cad6=Integer.parseInt(token.nextToken());
 
		System.out.println("Introduce sec:min:hour:day:month:year");
        cal1.setFecha(in.readLine());
*/
 
		System.out.print("Introduce the number of years: ");
		year = Integer.parseInt(year1 = in.readLine());
		System.out.print("Introduce the number of months: ");
		month = Integer.parseInt(month1 = in.readLine());
		System.out.print("Introduce the number of days: ");
		day = Integer.parseInt(day1 = in.readLine());
		System.out.print("Introduce the number of hours: ");
		hr = Integer.parseInt(hr1 = in.readLine());
		System.out.print("Introduce the number of minutes: ");
		min = Integer.parseInt(min1 = in.readLine());
		System.out.print("Introduce the number of seconds: ");
		sec = Integer.parseInt(sec1 = in.readLine());
 
		System.out.println("Time\tAmmount");
 
		for(int time=0;time<array.length;time++){
			System.out.println(time+"\t"+array[time]);
		}
 
	}
 
}

Output:

Introduce the number of years: 50
Introduce the number of months: 11
Introduce the number of days: 8
Introduce the number of hours: 10
Introduce the number of minutes: 2
Introduce the number of seconds: 25
Time	Ammount
0	0
1	0
2	0
3	0
4	0
5	0

I thought up of two ways of getting the user to input the specified information into the arrays, one is by the token part and another is simply asking for each single piece and storing them into variables.

I'm having trouble since this is my first time ever doing arrays.. First of all I would want to have the output display a table, under Time there would be: years,months,days,hours,minutes,seconds.
As you can see it will display from 0 to 5.. I find that obvious. And second column displays always 0.

How do I go about having the first column display strings for years,months,days,hours,minutes,seconds... and how do i get the array to order the variables instead of getting 0's?

how do i get the array to order the variables instead of getting 0's?

You must assign values to each slot in the array:
array[ix] = aValue; // set element ix to aValue

You should Try reading the tutorial.
Go to this site: http://download.oracle.com/javase/tu.../java/TOC.html
and Find array

ok so here is the code I got so far:

import java.io.*;
public class apples {
		public static void main(String[] args) throws IOException{
		BufferedReader in=new BufferedReader(new InputStreamReader (System.in));
 
		int array[]=new int[6];
		int year,month,day,hr,min,sec;
		int a=0,mo=12,d=30,h=24,mi=60,s=60;
		String year1,month1,day1,hr1,min1,sec1;
 
		System.out.print("Introduce the number of seconds: "); // 168
		sec = Integer.parseInt(sec1 = in.readLine());
		System.out.print("Introduce the number of minutes: "); // 190
		min = Integer.parseInt(min1 = in.readLine());
		System.out.print("Introduce the number of hours: "); // 50
		hr = Integer.parseInt(hr1 = in.readLine());
		System.out.print("Introduce the number of days: "); // 81
		day = Integer.parseInt(day1 = in.readLine());
		System.out.print("Introduce the number of months: "); // 23
		month = Integer.parseInt(month1 = in.readLine());
		System.out.print("Introduce the number of years: "); // 5
		year = Integer.parseInt(year1 = in.readLine());
 
		int secA = sec/s;
		int secB = sec-(secA*s);
/*		System.out.println("min "+secA);
		System.out.println("sec "+secB);*/
		int minA = (min+secA)/mi;
		int minB = (min+secA)-(minA*mi);
/*		System.out.println("hour "+minA);
		System.out.println("minute "+minB);*/
		int hrA = (hr+minA)/h;
		int hrB = (hr+minA)-(hrA*h);
/*		System.out.println("days "+hrA);
		System.out.println("hour "+hrB);*/
		int dayA = (day+hrA)/d;
		int dayB = (day+hrA) -(dayA*d);
/*		System.out.println("month "+dayA);
		System.out.println("day "+dayB);*/
		int monthA = (month+dayA)/mo;
		int monthB = (month+dayA)-(monthA*mo);
/*		System.out.println("year "+monthA);
		System.out.println("month "+monthB);*/
		int yearA = year+monthA;
/*		System.out.println("years "yearA);*/
 
		String[][] title = {{"Time ", "Time "}, {"Unit", "Duration"}};
		System.out.println(title[0][0] + title[1][0]+"\t"+ title[0][1] + title[1][1]);
		String[][] Units = {{"Seconds", "Minutes", "Hours"}, {"Days", "Months", "Years"}};
		System.out.println(Units[0][0]+"\t"+secB);
		System.out.println(Units[1][0]+"\t"+minB);
		System.out.println(Units[2][0]+"\t"+hrB);
		System.out.println(Units[0][1]+"\t"+dayB);
		System.out.println(Units[0][2]+"\t"+monthB);
		System.out.println(Units[0][3]+"\t"+yearA);
 
 
		System.out.println("years: "+yearA+" months: "+monthB+" days: "+dayB+" hours: "+hrB+" minutes: "+minB+" seconds: "+secB);
 
	}
 
}

the error/output is the following:

Introduce the number of seconds: 168
Introduce the number of minutes: 190
Introduce the number of hours: 50
Introduce the number of days: 81
Introduce the number of months: 23
Introduce the number of years: 5
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
	at apples.main(apples.java:52)
Time Unit	Time Duration
Seconds	48
Days	12

I'm confident there are easier ways to putting all this code... something more compact, but unfortunately I lack that knowledge, so rewarding the current structure of my code, how should I go about fixing this error?


-----------------

Fixed... sorry it's really late here and I just noticed my silly mistaken, here is the correction:

		String[][] title = {{"Time ", "Time "}, {"Unit", "Duration"}};
		System.out.println(title[0][0] + title[1][0]+"\t"+ title[0][1] + title[1][1]);
		String[][] Units = {{"Seconds", "Minutes", "Hours"}, {"Days", "Months", "Years"}};
		System.out.println(Units[0][0]+"\t"+secB);
		System.out.println(Units[0][1]+"\t"+minB);
		System.out.println(Units[0][2]+"\t"+hrB);
		System.out.println(Units[1][0]+"\t"+dayB);
		System.out.println(Units[1][1]+"\t"+monthB);
		System.out.println(Units[1][2]+"\t"+yearA);
