在Java中，創(chuàng)建類的實(shí)例對象是通過構(gòu)造方法實(shí)現(xiàn)的。首先，你需要確保類名遵循駝峰命名規(guī)則，即首字母大寫。構(gòu)造方法用于初始化對象屬性，通常在方法中通過傳入?yún)?shù)設(shè)置屬性值。然后，使用new關(guān)鍵字結(jié)合構(gòu)造方法調(diào)用來創(chuàng)建實(shí)例對象。下面是一個(gè)簡單的例子：public class Chetai {private double jiasu;private double jiansu;private double tingche;public Chetai(double jiasu, double jiansu, double tingche) { this.jiasu = jiasu; this.jiansu = jiansu; this.tingche = tingche;}public void setJiasu(double jiasu) { this.jiasu = jiasu;}public void setJiansu(double jiansu) { this.jiansu = jiansu;}public void setTingche(double tingche) { this.tingche = tingche;}public double getJiasu() { return jiasu;}public double getJiansu() { return jiansu;}public double getTingche() { return tingche;}public static void main(String[] args) { Chetai chetai = new Chetai(420, 300, 420); chetai.setJiasu(450); chetai.setJiansu(280); chetai.setTingche(400); System.out.println(chetai.getJiasu()); System.out.println(chetai.getJiansu()); System.out.println(chetai.getTingche());}}我建議，加速、減速、停車這些動作應(yīng)該有對應(yīng)的方法去設(shè)置速度。這樣不僅代碼結(jié)構(gòu)更加清晰，也便于維護(hù)。同時(shí)，你可以使用無參構(gòu)造函數(shù)，在使用set方法設(shè)置屬性。get方法獲取屬性值。你現(xiàn)在的水平剛開始學(xué)，加油了。
