How to convert String input to Float ? 1

[rpk2006]

Hi,

Please see my following code. At line 9, I am accepting user input, but I want to convert into float for calculation at line 11. How to do that ? I tried to repalce "String f" to "float f" at line 9, but it is giving error.

------------------------------------------------------------
package myprojects.temperature;

import java.io.*;

1 class Temperature
2 {
3 public static void main(String args[]) throws IOException
4 {
5 BufferedReader myIn = new BufferedReader(new InputStreamReader(System.in));

6 System.out.println("This program converts Temperature in Fahrenheit to Celsius"
7 System.out.println("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

8 System.out.println("Enter temperature in fahrenheit:"
9 String f = myIn.readLine();

10 // Calculation
11 float c = (f - 32) / 1.8;


12 // Display Result
13 System.out.println("Temparature in Celsius: " + c);
14 }
15 }
-------------------------------------- There is always a new solution for the same problem.

It's in the Javadoc for Float:

static float parseFloat(String s)
Returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.
