使用对象作为参数

public class Phone {
    private String color;
    private int price;
    private String brand;

    public Phone() {
    }

    public Phone(String color, int price, String brand) {
        this.color = color;
        this.price = price;
        this.brand = brand;
    }

    public String getColor() {
        return color;
    }

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

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

    public String getBrand() {
        return brand;
    }

    public void setBrand(String brand) {
        this.brand = brand;
    }
}
========================================

public class Phone1 {
    public static void main(String[] args) {
        Phone one=new Phone();
        one.setBrand("华为");
        one.setColor("金色");
        one.setPrice(8888);
        phone(one);
    }
    public static void phone(Phone phone1){
        System.out.println(phone1.getBrand());
        System.out.println(phone1.getColor());
        System.out.println(phone1.getPrice());
    }
}
