Question

Write two small code segments to calculate the cube value of an integer. The first code segment should calculate the cube value without using the Math library, the second should use the Math library in the calculation 5.

Answer 1

//TestCode.java
import java.util.Scanner;

public class TestCode{
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.println("Enter a number: ");
    int n = scanner.nextInt();

    System.out.println("Cube without using Math library = "+ (n*n*n));
    System.out.println("Cube using Math library = "+ (Math.pow(n,3)));
  }
}
