i'm learning java programing, i want to use while term but there is an error : illegal start of type :( what can i do?


public class WhileOrnek {

int i = 0 ;

System.out.println("i = " + i);
i++ ;

System.out.println("Sayma islemi tamamlandi.");
}
}

The problem is that the code needs to be inside a method inside the class. Try the following:
public class WhileOrnek
{
    public static void main(String[] args)
    {
        int i = 0;
        while (i < 5 )
        {
            System.out.println("i = " + i++);
            System.out.println("Sayma islemi tamamlandi.");
        }
    }
}
(I haven't tried to compile the code so please forgive any syntax typos.)

Vince.

A Turkish friend here has just translated the second println text for me, which suggests the following minor modification:
public class WhileOrnek
{
    public static void main(String[] args)
    {
        int i = 0;
        while (i < 5)
        {
            System.out.println("i = " + i++);
        }
        System.out.println("Sayma islemi tamamlandi.  (Counting process finished.)");
    }
}
