Object passing in Java

Object passing in Java

Give a simple example to illustrate

Requirement: enables you to get data from objects of the associated Car class by associating two classes with the person object

A person class, a Car class,

==> Person Class

class person{//  Setting Variables     private int pid;     private string pname;    private int page;     private car carname;       //   Multi-Parameter construction method      public person (string pname, int page) {         this.setpname (pname);         this.setpage (page);     }        public string getinfo () {         return  "Name: "  + getpname ()  +  "\ r"  +   "Age:"  + getpage ()  +  "\ r";    }         public void setcarname (Car carname) {         this.carname = carname;     }    public car getcarname () {         return this.carname;    }         public void setpname (String pname) {         This.pname = pname;    }    public string getpname () {        return this.pname;    }         public void setpage (int page) {         this.page = page;    }     Public int getpage () {        return this.page;     }    }

car  class

class car{    private string cname;    private  person pname;    //  Constructor     public car (String  CNAME) {        this.setcname (CNAME);    }         public void setpname (Person pname) {         this.pname = pname;    }     Public person getpname () {        return this.pname;     }        public void setcname (String  cname) {        this.cname = cname;     }    public string getcname () {         return this.cname;&Nbsp;   }        public string getcarinfo () {         return  "car Name:"  + getcname ();     }}

==> Test Class

public class Testdemo {public static void main (string[] args) {person p = new person ("Tom", 20); Car car = new car ("BMW");p. Setcarname (car); Car.setpname (P); System.out.println (P.getinfo ());//Gets the contents of its Car object through the Person object System.out.println (P.getcarname (). Getcarinfo ());//Through The Car object gets the contents of the Person Object System.out.println (Car.getpname (). Getpname ());}}
