class Auto {public int 轮胎数量;public String 汽车颜色;public double 车身重量;public double 速度;Auto() {// 无参构造}Auto(int 轮胎数量, String 汽车颜色, double 车身重量, double 速度) {// 有参构造this.轮胎数量 = 轮胎数量;this.汽车颜色 = 汽车颜色;this.车身重量 = 车身重量;this.速度 = 速度;}

Auto 类：

public class Auto {

private int num;//轮胎个数

private String coler; //颜色

private double weight; //重量

private double move; //速度

 

public Auto(){}

public Auto(int num){

 this.num = num;

}

public Auto(double weight){

 

 this.weight = weight;

}

public Auto(String coler){

 this.coler = coler;

}

 

public int getNum() {

 return num;

}

public void setNum(int num) {

 this.num = num;

}

public String getColer() {

 return coler;

}

public void setColer(String coler) {

 this.coler = coler;

}

public double getWeight() {

 return weight;

}

public void setWeight(double weight) {

 this.weight = weight;

}

public double getMove() {

 return move;

}

public void setMove(double move) {

 this.move = move;

}

 

}

实例化类：

public class Test {

 

 Auto a = new Auto();

 Auto a1 = new Auto(1);

 Auto a2 = new Auto("red");

 Auto a3 = new Auto(3.0);

 

}
