Write a Java program to Find the logarithmic value of a Number
This program calculates the logarithmic value of a number entered by the user using the Math.log() method in Java. Here's how the program works:
- The program starts by importing the java.util.* package which contains the Scanner class used for user input.
- The Logarithmic class is defined with a main method.
- Inside the main method, a new Scanner object X is created to read user input.
- A double variable num is initialized to zero.
- The program prompts the user to enter a number.
- The number entered by the user is read using the nextDouble() method of the Scanner class and assigned to the num variable.
- The program then calculates the logarithmic value of the number using the Math.log() method and prints the result to the console using System.out.print().
Source Code
import java.util.*;
public class Logarithmic
{
public static void main(String[] args)
{
Scanner X = new Scanner(System.in);
double num = 0;
System.out.print("Enter The Number : ");
num = X.nextDouble();
System.out.print("Logarithmic Value of Number is : " + Math.log(num));
}
}
Output
Enter The Number : 53
Logarithmic Value of Number is : 3.970291913552122
