Define a class person(pid,pname,gender,age).create n objects of person class using parametrized constructor and display using toString() method.

In this tutorial we are going to learn how we can Define a class person(pid,pname,gender,age).and also create n objects of person class using parametrized constructor and displaying by using toString() method.

Note :-

• return statement of  "True" is String not a boolean True.

Program :-(Define a class person(pid,pname,gender,age).create n objects of person class using parametrized constructor and display using toString() method)

import java.util.*;

class person

{

int pid,age;

String pname,gender;

person()

{

}

person(int p,int a,String pname,String gen)

{

this.pid=p;

this.age=a;

this.pname=pname;

this.gender=gen;

}

public String toString()

{

System.out.println("Person id is :"+pid);

System.out.println("Person Age is :"+age);

System.out.println("Person Name is :"+pname);

System.out.println("Person gender is :"+gender);

return "true";

}

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter How many Person details you want to store ?");

int n=sc.nextInt();

person p[]=new person[n];

for(int i=0;i<n;i++)

{

System.out.println("Enter Person Id :");

int pid=sc.nextInt();

System.out.println("Enter Person Age :");

int age=sc.nextInt();

System.out.println("Enter Person Name :");

String name=sc.next();

System.out.println("Enter Person gender :");

String gender=sc.next();

p[i]=new person(pid,age,name,gender);

}

for(int i=0;i<n;i++)

{

System.out.println("**********Person Details are ***********");

p[i].toString();

}

}

}

Output :-
