JAVA on the eighth week

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; arg constructor may have 
to assign for each property while creating an object; 
methods • 3.2 output notebook information 
• 3.3 and then write a test class, Test the various 
methods of the notebook class . 



package zuoye;
import java.util.Scanner;

        public class arc{
            public static void main(String[] args){
                Computer c1 = new Computer();
                c1.showComputer();
                Computer c2 = new Computer ('Red', 32 );
                c2.showComputer();
            }
            
        }
        class Computer{
            private char color;
            private int cpu;
            public Computer(){
                
            }
            public Computer(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;
            }
            public void showComputer(){
                System.out.println ( "Notebook color:" + getColor ());
                System.out.println ( "Notebook CPU model:" + getCpu ());
                
            }
        }
            

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 zuoye;

public class person {
    String name;
    int age;
    double height;
    
    person(String name,double d,double height){
        this.name=name;
        this.age=age;
        this.height=height;
    }
    void sayHello(){
        System.out.println("hello,my name is xx" );
        System.out.println("name"+"height"+"age");    
    }

public class personCreate {

        public void main(String[] args) {
            person c1 = new person("zhangsan", 1.73, 33);
            person c2 = new person("lishi", 1.74, 44);

            c1.sayHello();
            c2.sayHello();
        }
    }
}
