第八周上机作业

1.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。

class text3{

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

    public NoteBookComputer() {
    }

    public NoteBookComputer(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;
    }
}

2.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。

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

    }
}
public class person {
    private String Name;
    private double Tall;
    private int Age;

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

    public person(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;
    }
}
