Question

Java程序设计，创建一个汽车类CarModel.java，

它里面有2个不同的构造函数，CarManufactory.java可以应用这些构造方法创建不同类型的汽车 CarModel.java设计要求如下： 定义style(String)，color(String)，category(String)注：括号中为变量类型 创建第一个构造函数，分别给以上变量赋值，要求为该构造函数定义三个形参，分别赋给相应的变量，形参的值在对象创建时给出 创建第二个构造函数，此构造函数过程为空 定义三个方法，分别返回style，color，cat

Answer 1

public class CarManufactory{
private String style;
private String color;
private String category;

public String getStyle(){
return this.style;
}
public String getColor(){
return this.color;
}
public String getCategory(){
return this.category;
}

public CarManufactory(String style,String color,String category){
this.style = style;
this.color = color;
this.category = category;
}
public CarManufactory(){}
}

Answer 2

public class CarManufactory {
private String style;
private String color;
private String category;
public CarManufactory(String style, String color, String category) {
super();
this.style = style;
this.color = color;
this.category = category;
}
public CarManufactory() {
super();
// TODO Auto-generated constructor stub
}
public String getStyle() {
return style;
}
public String getColor() {
return color;
}
public String getCategory() {
return category;
}
}

Answer 3

public class CarModel{

private String style;
private String color;
private String category;

public CarModel(String style, String color, String category) {
this.style = style;
this.color = color;
this.category = category;
}

public CarModel(){}

public String getStyle() {
return style;
}

public String getColor() {
return color;
}

public String getCategory() {
return category;
}

}
