Write a program to display properties of Mobile using class & object in the oops concept

Share Your Love

Hello guys, welcome to lingarajtechhub.com . Today we are going to discuss display properties of Mobile using class & object in the oops concept.

Code:

 package com.Mobile_oops_class_obj.java;

import java.util.Scanner;

public class Mobile {
	String Model, colour;
	
	void Mobile_input() {
		System.out.println("Enter value of model & colour:");
		Scanner sc=new Scanner(System.in);
		Model=sc.next();
		Colour=sc.next();
	}
    void Mobile_Display() {
    	System.out.println("Mobile model:"+Model);
    	System.out.println("Mobile Colour:"+colour);
    	
    }
	public static void main(String[] args) {
		Mobile m=new mobile();
		m.Mobile_input();
		m.Mobile_Display();
	}

}

Line-1:

  •  package com.Mobile_oops_class_obj.java;

 It is a java package , this package is created in a java project and it contains classes inside the package.

Line-3:

  • import java.util.Scanner;

In java, Scanner is a class. util package used for obtaining the input of the data  types like int, double, float , char  and strings.

Line-5:

  • public class Mobile

Mobile” is the class-name , class is a template used to create objects & class-name first letters must be capital. It is public means we can use this outside of the package.

Line-6:

  • String Model,colour

Here Model , colour are the variable and String is a class. It is not a data type.

Line-8:

  • void Mobile_input() {

            System.out.println(“Enter value of Model & colour :”)

 In this line  we create a method whose name takes Mobile_input().system is a predefined  class .Out is a static variable of type printstream present in system class. Println shows the result.

Line-10:

  • Scanner sc=new Scanner(System.in)

Scanner is a class and sc is the instance of the object which is the new Scanner . System.in is an argument.

Line-11:

  • Model =sc.next();
  • colour=sc.next();

 Model , colour are the variables that we take and sc is our instance name which is created for an object and next() is a method of a Scanner object that reads in a string of digits or char and converts them into an String type.

Line-14:

  • void Mobile_Display() {

            System.out.println(“Mobile model:”+Model);

System.out.println(“Mobile colour:”+colour); 

       }

In this line  we create a method whose name takes Mobile_display().system is a predefined  class .Out is a static variable of type printstream present in system class. Println shows the result.

Line-19:

  • public static void main(String[] args) 

It is a main method in which we can execute a program.

  •  public : It is an access modifier. The main() is public because we can access main() outside of the class , if main() can’t be public then JVM(Java Virtual Machine) can’t be called main() & code can’t be executed. 
  •  Static : static is a keyword in which the main method has to be static in which JVM can load the class into memory and call the main method without creating an instance.
  •  Void : Void is a data type. It means no return type. 
  •  main(): Main is a function. 
  •  String [] args : string means collection of characters ,String[] args represents a collection of Strings that are separated by a space and can be typed into the program on the terminal directly.

Line-20:

  • Mobile m=new Mobile()

Here “m” is the instance variable.It is created to assign the default values to the instance variables of the class when an object is created.

  • m.Mobile_input()

“m” is the instance variable which is created. “ .” is the connector Mobile_input() is a method where our input values will be stored.

  • m.Mobile_Display();

“m” is the instance variable which is created. “ .” is the connector .Mobile_display() is a method where our result will be stored.
