Java Program to Find Cube of a Number

In this program, we will learn to code the Java Program to Find Cube of a Number. Let’s understand How to calculate cube of a number in Java Programming Language. In the previous program, we have learned to code the Java Program to Find Square of a Number.

We are going to solve this Java Program to Find Cube of a Number using two approaches as follow

  • Using Math.pow() fuction
  • Using “*” operator

Now, let’s get straight into the code of the Java Program to Find Cube of a Number.

Java Program to Find Cube of a Number

Using Math.pow Function

Let’s see the code of the Java Program to Find Cube of a Number using Math.pow() function.

import java.util.*;
import java.lang.*;

class Main
{
	public static void main (String[] args)
	{
		    Scanner sc = new Scanner(System.in);
		    System.out.println("Enter the number: ");
		    int num = sc.nextInt();
		    
		    //Calculating the cube of the number
		    int cube = (int) Math.pow(num,3);
		    
		    System.out.println("Cube of the number "+num+" is "+cube+" .");
		 
	}
}

Output

Enter the number: 7
Cube of the number 7 is 343 .

How Does This Program Work ?

        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the number : ");
        int num = sc.nextInt();

In this program, we have taken the input of the number we want to calculate the cube of using the Scanner class in Java.

                    //Calculating the cube of the number
		    int cube = (int) Math.pow(num,3);

Then, we have used the Math.pow() function in Java to calculate the cube of the number. The Math.pow() function returns a double value, so, to store the number in int type we have explicitly typecasted it.

		    System.out.println("Cube of the number "+num+" is "+cube+" .");

Then, we displayed the result.

This is the Java Program to Find Cube of a Number using Math.pow() function. Now, let’s see another approach using “*” operator.

Java Program to Find Cube of a Number

Using “*” Operator

Let’s see the code of the Java Program to Find Cube of a Number using “*” operator.

import java.util.*;
import java.lang.*;

class Main
{
	public static void main (String[] args)
	{
		    Scanner sc = new Scanner(System.in);
		    System.out.println("Enter the number: ");
		    int num = sc.nextInt();
		    
		    //Calculating the cube of the number
		    int cube = num * num * num;
		    
		    System.out.println("Cube of the number "+num+" is "+cube+" .");
		 
	}
}

Output

Enter the number: 11
Cube of the number 11 is 1331 .

This is the Java Program to Find Cube of a Number using “*” operator.
