How to cube in java - Java Program to Find Cube of a Number

How to cube in java: In the previous article, we have seen Java Program to Check if Number is Divisible 5 and 11

In this article we will see how to find cube of a number using Java programming language.

Java Program to Find Cube of a Number

Cube of a number represents multiplying the number with itself for 3 times.

For example

Cube of 3 = (3*3*3) = 27

Cube of 15 = ( 15*15*15) = 3375

Let’s see different ways to find cube of a number.

By Using Static Input Value
By Using User Input Value
By Using User Defined Method

Method-1: Java Program to Find Cube of a Number By Using Static Input Value

Approach:

Declare an integer variable say ‘number‘ and initialize a value to it.
Find cube by multiplying the number with itself for 3 times.
Print the result.

Program:

public class Main 
{
   public static void main(String args[])
   {
      //a number declared
      int number = 5;
      //finding cube of number by multiplying it 3 times with itself
      //and printing result
      System.out.println("Cube of number: "+ (number*number*number));
   }
}

Output:

Cube of number: 125

Method-2: Java Program to Find Cube of a Number By Using User Input Value

Approach:

Declare an integer variable say ‘number‘ and take the value as user input by using Scanner class.
Find cube by multiplying the number with itself for 3 times.
Print the result.

Program:

import java.util.*;

public class Main 
{
   public static void main(String args[])
   {
      Scanner sc=new Scanner(System.in);
      
      //taking a number input from user
      System.out.println("Enter a number: ");
      int number = sc.nextInt();
      //finding cube of number by multiplying it 3 times with itself
      //and printing result
      System.out.println("Cube of number: "+ (number*number*number));
   }
}

Output:

Enter a number: 
15
Cube of number: 3375

Method-3: Java Program to Find Cube of a Number By Using User Defined Method

Approach:

Declare an integer variable say ‘number‘ and take the value as user input by using Scanner class.
Call user defined method findCube() and pass the number as parameter.
Inside method find cube by multiplying the number with itself for 3 times.
Print the result.

Program:

import java.util.*;

public class Main 
{
   public static void main(String args[])
   {
      Scanner sc=new Scanner(System.in);
      
      //taking a number input from user
      System.out.println("Enter a number: ");
      int number = sc.nextInt();
      //calling user defined method findCube()
      findCube(number);
   }
   
   //findCube() method to find cube of a number
   public static void findCube(int number)
   {
      //finding cube of number by multiplying it 3 times with itself
      int cube = number*number*number;
      //printing result
      System.out.println("Cube of number: "+ cube);
   }
}

Output:

Enter a number: 
6
Cube of number: 216
