public void setSu(Double su) {
this.su = su;
}

public String getPingpai() {
return pingpai;
}

public String getColor() {

}

public Double getSu() {
return su;
}

@Override
public String toString() {
return "Car [pingpai=" + pingpai + ", color=" + color + ", su="
+ su + "]";
}
}

package Help3;

public class CarTest {

public class Car {
private String brand;
private String color;
private double speed;

public Car(String _brand, String _color) {
brand = _brand;
color = _color;
speed = 0;
}

public String getBrand(){
return brand;
}

public String getColor(){
return color;
}

public void setColor(String newcolor){
color = newcolor;
}

public double getSpeed(){
return speed;
}

public void setSpeed(double newspeed){
speed = newspeed;
}

}

public class CarTest {

public static void main(String[] args) {
// TODO Auto-generated method stub
Car myCar = new Car("Benz", "black");
System.out.println(myCar.getBrand());
}

}

注意class Car放到Car.java里，class CarTest放到CarTest.java里

//car类文件
Class Car{
private String brand;

private String color;
private double speed;
public Car(String brand,String color){
this.brand=brand;
this.color=color;
this.speed=0.0d;

}
public String getBrand(){
return this.brand;

}
public String getColor(){
return this.color;

}
public setColor(String color){
this.color=color;

}
public double getSpeed(){
return this.speed;

}
public setSpeed(double speed){
this.speed=speed;

}
}

//主类文件
Class CarTest{
public static void main(String[] args){
Car car=new Car("benz","black");

}

}
纯手打，可能有编译错误

public class Car {
private final String brand;
private final String color;
private Double speed;

Car (String brand , String color ) {
this.brand = brand;
this.color = color;
this.speed = 0d;
}

public static void main(String args[]){

}
}

public class TestCar {
public static void main(String args[]){
Car car = new Car("benz", "black");

}
}

按你的要求写的两个类
