How to find the volume of cube using Scanner class

Hello guys, welcome to Lingarajtechhub. Today we are going to discuss how to find the volume of cube using Scanner class

Code:

package com.Arithmatic_operator.java;
import java.util.Scanner;
public class Volume_Cube
{
	 public static void main(String[] args) 
     {
		double volume,edge;
		Scanner sc=new Scanner(System.in);
        System.out.println("Entr the edge of a cube ");
		edge=sc.nextDouble();
		volume=edge*edge*edge;
		System.out.println("The volume of a cube  "+volume );
		
	}

}

Line-1:

package com.Arithmatic_operator.java;

–> it is a java package( com.Arithmatic_operator.java) which is collection of classes and this package is created in java project.

Line-2:

import java.util.Scanner;

–>Scanner is a class in java. util package used for obtaining the input of the primitive types like int, double, etc. and strings.

Line-3:

public class Volume_Cube

–> Here Volume_Cube is defined as a class which is a template used to create objects and to define object data types and methods .
–> And is defined as public because it accesses anywhere.

Line-5:

public static void main(String[] args)

–>It is a main method in which we can execute a program
–>public :it is a access modifier of the main function which is must be public so that the JRE which is (Java Run Time Environment)can access and execute this method.
–> If a method is not public, then access is restricted and its showing error
–> static is a keyword in which main method has must to be static in which JVM can load the class into memory and call the main method without creating an instance
–> void it means no return type
–> main() is function
–> string[]args : string means collection of charecters ,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-7:

double volume,edge;

–> Here we Declare 2 variable volume,edge which is double type.

Line-8:

Scanner sc=new Scanner(System.in);

–> Here scanner is a class and Sc is the instance of the object which is new Scanner.System.in is an argument.

Line-9:

System.out.println(“Entr the edge of a cube “);

–> It means System is a class name and out is an instance of the System println is print a new line

Line-10:

edge=sc.nextDouble();

–> Here edge is a variable that we take and sc is our instance name which is create for a object and nextDouble() is a method method of a Scanner object reads in a string of digits or char and converts them into a double type.

Line-11:

volume=edge;
