Noob question about a statement in a Java program
- by happysoul
I am beginner to java and was trying out this code puzzle from the book head first java which I solved as follows and got the output correct :D
class DrumKit
{
boolean topHat=true;
boolean snare=true;
void playSnare()
{
System.out.println("bang bang ba-bang");
}
void playTopHat()
{
System.out.println("ding ding da-ding");
}
}
public class DrumKitTestDriver
{
public static void main(String[] args)
{
DrumKit d =new DrumKit();
if(d.snare==true)
{
d.playSnare();
}
d.playTopHat();
}
}
Output is ::
bang bang ba-bang
ding ding da-ding
Now the problem is that in that code puzzle one code snippet is left that I did not include..it's as follows
d.snare=false;
Even though I did not write it , I got the output like the book. I am wondering why is there need for us to set it's value as false even when we know the code is gonna run without it too !??
I am wondering what the coder had in mind ..I mean what could be the possible future use and motive behind doing this ?
I am sorry if it's a dumb question. I just wanna know why or why not to include that particular statement ? It's not like there's a loop or something that we need to come out of. Why is that statement there ?
