java - 如何使用 for 循环增加一项并减少第二项

Question

我想达到以下结果:如果速度增加 1，gasLiter 就会减少 0.25。有人可以帮忙吗？这是我的代码:

public class Gas extends Car{

    public Gas (String wheels, String frame, double engine, int maxSpeed) {
        super (wheels, frame, engine, maxSpeed);

        for (int speed = 0; speed<maxSpeed; speed++) {
            for (double gasLiter= 60; gasLiter <60; gasLiter-=0.25){

Answer 1

您需要一个循环:

double gasLiter = 60;
for (int speed = 0; speed < 800; speed++, gasLiter-=0.25) {

}

您还可以添加第二个停止条件:

double gasLiter = 60;
for (int speed = 0; speed < 800 && gasLiter >= 0; speed++, gasLiter-=0.25) {

}

我假设你原来的 gasLiter < 60条件是一个错误。
