java

1. 创建 Phone 类

package class_object;

public class Phone {

    String brand;
    String color;
    double price;
    
    void call(String who){
        System.out.println("call "+who);
    }
    
    void sendMes(String message){
        System.out.println("send "+message);
    }
    
}

2.  创建使用 Phone 类 ,  对象装载数据传递到方法中

package class_object;
/**
 * 类 做为方法的参数
 */
public class ClassParam {

    public static void main(String[] args) {
        Phone p = new Phone();
        p.brand = "华为";
        p.color = "red";
        p.price = 4999;
        ts(p);
    }
    
    /**
     * 对象装载数据
     */
    public static void ts(Phone param) {
        System.out.println(param.brand);
        System.out.println(param.price);
        System.out.println(param.color);
        param.call("罗汉堂");
        param.sendMes("有内鬼,中止交易");
    }

}
