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); } }
