我的目标是创建Dragster和Dragrace类。我的dragster类已经完成，但是我对如何完成我的DragRace类一无所知。主要方法应该显示这样的结果。
减速器特性：反应时间：0.6，扭矩：1000，牵引力：0.8286078156824775，燃烧时间：3
Dragster时间：6.663417763058126秒。
我必须创建一个包含5个Dragster的数组，然后显示每个数组的结果。
public class Dragster {
private int burnTime;
private double reactionTime;
private int torque;
private double traction;
public Dragster(double reactionTime, int torque, double traction, int burnTime) {
this.reactionTime = reactionTime;
this.torque = torque;
this.traction = traction;
this.burnTime = burnTime;
}
private double conditionTires(double time){
double effectiveness = 2.5*(Math.exp((time * time - (10 * time) + 25) / 50))/Math.sqrt(2 * Math.PI);
return effectiveness;
}
public void burnout(){
traction = traction * conditionTires(burnTime);
}
public double race(){
double TORQUE2TIME = 5000;
double raceTime = reactionTime + (1/(torque/ TORQUE2TIME)*conditionTires(burnTime));
return raceTime;
}
public String toString(){
return "Reaction Time:" + reactionTime + ", Torque:" + torque + "Traction:" + traction +
"Burn Time:" + burnTime;
}
}
public class DragRace {
private DragRace{
}
public static void main(String[] args){
ArrayList<Dragster> DragsterList = new ArrayList<Dragster>();
Dragster car1 = new Dragster(0.6, 1000, 0.9, 3);
Dragster car2 = new Dragster(0.4, 800, 1.0, 5);
Dragster car3 = new Dragster(0.5, 1200, 0.95, 7);
Dragster car4 = new Dragster(0.3, 1200, 0.95, 1);
Dragster car5 = new Dragster(0.4, 900, 0.9, 6);
DragsterList.add(car1);
DragsterList.add(car2);
DragsterList.add(car3);
DragsterList.add(car4);
DragsterList.add(car5);
DragsterList.toString();
}
}
我在dragrace课上迷失了下一步的工作。如果有人可以提供一些见识。
最佳答案
只需执行以下操作：
public void printResults() {
for (Dragster d: DragsterList) {
System.out.println(d.toString());
System.out.println();
System.out.println("Dragster time:" + d.race());
}
}
基本上，您只需要遍历列表中的每辆汽车，打印汽车并进行一次赛车。
