OneSurvivor :
I have to assign a random amount of objects in this program, and currently the only way I know to do this is something like this:
if (star.returnZones() == 1) {
this.createPlanet(planet1, star);
}
else if (star.returnZones() == 2) {
this.createPlanet(planet1, star);
this.createPlanet(planet2, star);
}
else if (star.returnZones() == 3) {
this.createPlanet(planet1, star);
this.createPlanet(planet2, star);
this.createPlanet(planet3, star);
}
else if (star.returnZones() == 4) {
this.createPlanet(planet1, star);
this.createPlanet(planet2, star);
this.createPlanet(planet3, star);
this.createPlanet(planet4, star);
}
else if (star.returnZones() == 5) {
this.createPlanet(planet1, star);
this.createPlanet(planet2, star);
this.createPlanet(planet3, star);
this.createPlanet(planet4, star);
this.createPlanet(planet5, star);
}
I am sure this is a far more efficent way to do this, where each one does something along the lines of this. I will be using the term asAbovePlus to mean everything above, plus one more thing.
if (star.returnZones() == 1) {
this.createPlanet(planet1, star);
}
else if (star.returnZones() == 2) {
asAbovePlus
this.createPlanet(planet2, star);
}
Is there a way to do something like this in Java? It would really help out.
njzk2 :
Start by removing the duplicates:
int zones = star.returnZones();
if (zones >= 1) {
createPlanet(planet1, star);
}
if (zones >= 2) {
createPlanet(planet2, star);
}
...
You can see that in the example where zones == 2
, it does execute the 2 blocks, so you keep the same functionality.
Then, you can see that this is actually a loop. Start by putting the planets in an array:
Planet[] planets = new Planet[] {planet1, planet2, ...};
for (int i = 0; i < star.returnZones(); i++) {
createPlanet(planets[i], star);
}
