sir pahelp nmn po,,,ahm gagawa po kmi ng program na mag add ng 2 numbers,,
gagawa po kmi ng include file name as sum2.h and sum.h

e2 po ung sum2.h

class Sum
{
public:
Sum();
Sum(int xx,int yy);
int getX();
int getY();
void add(int xx, int yy);
int getSum() const;
private:
int x;
int y;
int sum;
};

e2 nmn po ung sum.h

#include "Sum2.h"
Sum::Sum()
{x=0;
y=0;
}

Sum::Sum(int xx, int yy)
{x=xx;
y=yy;
}

int Sum::getX()
{return(x);
}

int Sum::getY()
{return

;
}

void Sum::add(int xx, int yy)
{sum=xx+yy;
}

int Sum::getSum() const
{return (sum);
}

e2 nmn po ung main program:

#include "sum.h"
#include <stdio.h>
#include <conio.h>

void main()
{int a,b;
printf("Enter two numbers:");
scanf("%d %d",&a,&b);
Sum mySum(a,b);
mySum.add(mySum.getX(),mySum.getY());
printf("%d",mySum.getSum());
getch();
}

hndi ko po xa maparun,,declaration syntax error po,,anu po b mali ko? sna po matulungan nyu ako,,tnx po in advance!! :help:

Pa tulong po sa java ko.

Urgg, i need help with my combobox.

I've made 3 combobox.
1 for months , 1 for days, and 1 for years;

This is I what I plan,

if they choose january, the days will have 31, if february the days will be 28 only.

but I don't know how to change the items inside the combobox during runtime.

Code:

btnenter.addActionListener( // I just tried to use it in JButton
         new ActionListener(){
            public void actionPerformed(ActionEvent e){
               
               day.removeAllItems();
               day.addItem(days31); //days31 is a String that has 31 items. But when I use this there's an error in the output
            }
         }   
      );

Use java.awt.event.ItemListener instead of java.awt.event.ActionListener.

Snippet

Code:

import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;

JComboBox monthComboBox = new JComboBox();
monthComboBox.addItemListener(new ItemListener() {
	public void itemStateChanged(ItemEvent e) {
		...
	}
});

patulong naman po sa java.

kelangan ko po kasi gumawa ng program na mai-output kung ilan yung digits ng i.d number.

example:
Enter I.D number: 201010065
(sa isang variable lang dapat sya nakalagay)

ang output nya dapat "9".

tapos kelangan din sabihin ng program kung ilan ang odd tsaka even numbers dun.

Di ko po talaga alam kung pano gagawin dito. Sana po may makatulong. :pray:

nicktunac · Oct 1, 2011

@yash

ganun parin po.

day.addItem(day30); ganito kasi ginagawa ko.
day30 is string that compose by 1~30.

Di ko kasi alam proper syntax para jan.
ung actionListener pantest ko if iclick ko ung btnok magpapalit ung entry ng combobox

pede po pa add fb magtatanung lang ^_^

kung integer yung variable na ginamit mo para paglagyan ng input, int length = Integer.toString(IDnumber).length();

kung string naman, int length = IDnumber.length();

sana makatulong :thumbsup:

gawa ka ng character array of correct answers kunwari..

Code:

char ans[] = "abcabccbaa";

tapos check mo yung answer na ininput ng user sa array mo..

simula ans[0] hanggang ans[9].. yung [0] yung first question, marunong ka naman siguro mag compare ng characters di ba? hehe..

pag correct (pareho yung answer dun sa character array mo) lagay ka ng correct answer na counter.. tapos pagkatapos ng program, eh di yung value ng counter mo eh divide mo sa total number of questions para sa average..
