第八次上机练习

3、定义一个笔记本类，该类有颜色（char）和cpu
型号（int）两个属性。

package yukikaze;
public class mhm {
    public static void main(String[] args) {
        m nbc=new m('黑',1080);
        System.out.println("颜色；"+nbc.getColor()+"   "+"cpu:"+nbc.getCpu());
        m nbc2=new m();
        nbc2.setColor('红');
        nbc2.setCpu(1060);
        System.out.println("颜色；"+nbc2.getColor()+"   "+"cpu:"+nbc2.getCpu());
    }
}

package yukikaze;

public class m {
    private char color;
    private int cpu;

    public m() {
    }

    public m(char color, int cpu) {
        this.color = color;
        this.cpu = cpu;
    }

    public char getColor() {
        return color;
    }

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

    public int getCpu() {
        return cpu;
    }

    public void setCpu(int cpu) {
        this.cpu = cpu;
    }
}

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 yukikaze;
public class mhm {
    public static void main(String[] args) {
        m p=new m("zhangsan",1.73,33);
        p.sayHello();
        m p2=new m("lisi",1.74,44);
        p2.sayHello();
        }
}

package yukikaze;

public class m {
     private String Name;
        private double Tall;
        private int Age;

        public void sayHello(){
            System.out.println("你好我们名字叫"+Name);
        }
        public m() {
        }

        public m(String name, double tall, int age) {
            Name = name;
            Tall = tall;
            Age = age;
        }

        public String getName() {
            return Name;
        }

        public void setName(String name) {
            Name = name;
        }

        public Double getTall() {
            return Tall;
        }

        public void setTall(Double tall) {
            Tall = tall;
        }

        public int getWeight() {
            return Age;
        }

        public void setWeight(int weight) {
            this.Age = weight;
        }
}
