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

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

Code:

package com.Tv_oops_class_obj.java;
import java.util.Scanner;
public class Tv {
	int size;
	String Company;
	
	void Tv_input() {
		System.out.println("Enter value of size & Company:");
		Scanner sc=new Scanner(System.in);
		size =sc.nextInt();
		Company=sc.next();
	}
    void Tv_Display() {
    	System.out.println("TV size:"+size);
    	System.out.println("TV Company:"+Company);
    	
    }
	public static void main(String[] args) {
		Tv t=new Tv();
		t.Tv_input();
		t.Tv_Display();
	}

}

Line-1:

package com.Tv_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-2:

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-3:

public class Tv

“Tv” 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-4:

int size

Here size is the variable and int (Integer) is a data type of the variable.

Line-5:

String Company

Here the Company is the variable and String is a class. It is not a data type.

Line-7:

void Tv_input() {

System.out.println(“Enter value of size & Company:”)

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

Line-9:

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-10:

size =sc.nextInt();
Company=sc.next();

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

Line-13:

void Tv_Display() {

System.out.println(“Tv size:”+size);

System.out.println(“Tv Company:”+Company);

}

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

Line-18:

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.
