I have a problem regarding java code
i want a code that display a message after a specific days
my idea is to use
int day;
final day = 31;
if (days <=31)
System.out.println ("Please restock");
that the idea…
somehow it seems illogical….
anyone can help please help…..
It is really a bad programming, but if you are a beginner you are allowed to do this mistake a couple of times!
Generally you could return more than one object in a java method by using an array. For example the following method returns an Object array:
Object[] testMethod() {
Object a,b;
........
........
Object[] obj = new Object[2];
obj[0]=a;
obj[1]=b;
return obj;
}
You can access the returned value by:
Object[] ret = testMethod(); System.out.println(ret[0]); System.out.println(ret[1]);
Here is my timer example, enjoy:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Timer;
public class TimerTest {
public static void main(String[] args) {
Timer timer = new Timer(1000, new Listener()); //creates a timer
//that ticks once every
//second and creates a new
//ActionListener timer.start(); //starts the timer while(true);
//Infinite loop that insures the program won't end
//if it wasn't here the program would end before the
//timer has a chance to start. } }
class Listener implements ActionListener {
private int minutes = 0;
private int hours = 0;
private int secs = 0;
@Override public void actionPerformed(ActionEvent e) {
secs++; if(secs == 60)
{ secs = 0; minutes++; if(minutes == 60) { minutes = 0; hours++; } }
System.out.println(hours + " : " + minutes + " : " + secs); } }
