dog()
{
for (int i=1;i<10;)
System.out.println(i);
}
this function will never end ,it will print endless1 because it do nothing after the judgement i<10
but why the function below runs ok?
public static void print(Collection c)
{
for (Iterator x=c.iterator();x.hasNext();)
System.out.print(x.next()+" ");
System.out.println();
}
