3、定义一个笔记本类,该类有颜色(char)和cpu
型号(int)两个属性。 [必做题]
• 3.1 无参和有参的两个构造方法;有参构造方法可
以在创建对象的同时为每个属性赋值;
• 3.2 输出笔记本信息的方法
• 3.3 然后编写一个测试类,测试笔记本类的各个
方法。

package chap1;

public class Main {
    public static void main(String[] args){
    }
     char colour;
        int cpu;
        public char getYs() {
            return colour='q';
        }
        public int getCpu() {
            return cpu=865;
        }
        public void shuchu() {
            System.out.println("颜色是:"+getYs()+"\t"+"cpu型号是:"+getCpu());
        }
}
package chap1;

public class Main {
    public static void main(String[] args){
    }
    char colour;
    int  number;
    note (){
    }
    note(char colour ,int number)
    {
        this.colour=colour;
        this.number=number;
    }
    void a()
    {
        System.out.println("颜色:"+colour+"型号"+number);
        
    }
     public static void main(String[] args)
     {
         note a =new note ('a',6589);
         a.a();
     }
}

5、定义两个类,描述如下: [必做题]
• 5.1定义一个人类Person:
• 5.1.1定义一个方法sayHello(),可以向对方发出问
候语“hello,my name is XXX”
• 5.1.2有三个属性:名字、身高、体重
• 5.2定义一个PersonCreate类:
• 5.2.1创建两个对象,分别是zhangsan,33岁,1.73
;lishi,44,1.74
• 5.2.2分别调用对象的sayHello()方法。

package chap1;

public class Main {
    String name;
    double height;
    int age;

   void note(String name, double height, int age) {
        this.name = name;
        this.height = height;
        this.age = age;
    }

    void sayHello() {
        System.out.println("hello,my name is  " + name+" "+height+"m"+" "+age+"岁");
    }
    public static void main(String[] args)
    {
    note a = new note();
     

    a.sayHello();
    

}
}
package chap1;

public class Main {
     String name;
        double height;
        int age;

       void note(String name, double height, int age) {
            this.name = name;
            this.height = height;
            this.age = age;
        }

        void sayHello() {
            System.out.println("hello,my name is  " + name+" "+height+"m"+" "+age+"岁");
        }
        public static void main(String[] args)
        {
        note a = new note();
         

        a.sayHello();
        

    }
    }
