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

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.
