Java's sixth computer operation

3. Define a notebook class with
two attributes: color (char) and cpu model (int). [Will do questions]
• 3.1 and two no-argument constructor has the Senate; constructor can have parameters
at the same time create an object for each property assignment; [not] temporarily
• 3.2 notebook information output method
• 3.3 and Write a test class to test the various methods of the notebook class
.

package Rectangle;
public class book {
        char color;
        int cpu;
        public void com() {
            System.out.println ( "Color is" + color);
            System.out.println ( "cpu model is" + cpu);
     
        }
     
    }

package Rectangle;

public class Text {
    public static void main(String[] args) {
                // TODO Auto-generated method stub
                book p1 = new book();
                p1.color='c';
                p1.cpu=5;
                p1.com();
         
            }
         
        }

 

 

 

5, define two classes, described as follows: [will do questions]
• 5.1 definition of a human the Person:
• 5.1.1 define a method sayHello (), you can send out to ask each other
greeting "the Hello, My name IS XXX"
• 5.1 .2 has three attributes: name, height, and weight
• 5.2 defines a PersonCreate class:
• 5.2.1 creates two objects, namely zhangsan, 33 years old, 1.73
; lisi, 44, 1.74
• 5.2.2 calls the sayHello of the objects respectively ()method.

 package Rectangle;

public class person {
    String name;
    double height;
    int age;
    public void Hello() {
        System.out.println("Hello,my name is   "+name);
        System.out.println("my height is   "+ height);
        System.out.println("my age is  "+ age);
    }
    
}

package Rectangle;

public class PersonCreate {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        person p1 = new person();
        p1.name="zhangsan";
        p1.age=33;
        p1.height=1.73;
        person p2 = new person();
        p2.name="lisi";
        p2.age=44;
        p2.height=1.74;
        p1.Hello();
        p2.Hello();
         
    }

}
