Conversion of Celsius to Fahrenheit and Vice Versa using JAVA

The Java code is right here to show. 
  1. import java.io.BufferedReader;  
  2. import java.io.InputStreamReader;  
  3. import java.util.Scanner;  
  4. class Demo {  
  5.     public static void main(String[] args) throws Exception {  
  6.         float Ctemperature, Ftemperature;  
  7.         Scanner in = new Scanner(System. in );  
  8.         BufferedReader br = new BufferedReader(new InputStreamReader(System. in ));  
  9.         System.out.println("1-Celsius to Fahrenheit..?");  
  10.         System.out.println("2-Fahrenheit to Celsius..?");  
  11.         System.out.println();  
  12.         System.out.print("Select any option: ");  
  13.         int select = Integer.parseInt(br.readLine());  
  14.         switch (select) {  
  15.             case 1:  
  16.                 System.out.print("Enter temperatue in Celsius: ");  
  17.                 Ctemperature = in .nextInt();  
  18.                 Ftemperature = (Ctemperature * 9) / 5 + 32;  
  19.                 System.out.println("Temperatue in Fahrenheit = " + Ftemperature);  
  20.                 break;  
  21.             case 2:  
  22.                 System.out.print("Enter temperatue in Fahrenheit: ");  
  23.                 Ftemperature = in .nextInt();  
  24.                 Ctemperature = ((Ftemperature - 32) * 5) / 9;  
  25.                 System.out.println("Temperatue in Celsius = " + Ctemperature);  
  26.                 break;  
  27.             default:  
  28.                 System.out.println("Wrong choice :(");  
  29.         }  
  30.     }  
  31. }
