SPARETIRE(Java SpareTire類使用實例)

下面是一個Java SpareTire類的實例:

public class SpareTire {private int diameter;private String brand;public SpareTire(int diameter, String brand) {this.diameter = diameter;this.brand = brand;}public int getDiameter() {return diameter;}public void setDiameter(int diameter) {this.diameter = diameter;}public String getBrand() {return brand;}public void setBrand(String brand) {this.brand = brand;}public void inflate() {System.out.println("Inflating spare tire");}public void changeBrand(String newBrand) {System.out.println("Changing spare tire brand from " + brand + " to " + newBrand);this.brand = newBrand;}public static void main(String[] args) {// 創建一個SpareTire對象SpareTire spareTire = new SpareTire(16, "Goodyear");// 調用對象的方法System.out.println("Spare tire diameter: " + spareTire.getDiameter());System.out.println("Spare tire brand: " + spareTire.getBrand());spareTire.inflate();spareTire.changeBrand("Michelin");System.out.println("New spare tire brand: " + spareTire.getBrand());}}

這個SpareTire類表示一個備用輪胎,它有一個直徑和品牌屬性,以及一些操作這些屬性的方法。在main方法中,我們創建一個SpareTire對象,并調用它的方法來獲取和修改屬性,并執行一些其他操作。最后,我們打印出修改后的屬性值。
