public class TemperatureConversionProgramUsingSwitchStatementExample {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter 1 for Fahrenheit to Celsius \n"
+ "Enter 2 for Celsius to Fahrenheit conversion : ");
int operation = scanner.nextInt();
System.out.print("Enter temperature : ");

/*
* Perform temperature conversion using switch statement in Java.
*/
switch (operation) {
//Fahrenheit to Celsius temperature conversion
case 1:
convertedTemperature = ((temperature - 32) * 5) / 9;
System.out.println(temperature + " Fahrenheit " + " in Celsius = "
+ convertedTemperature);
break;
//Celsius to Fahrenheit temperature conversion
case 2:
convertedTemperature = (9 * temperature / 5) + 32;
System.out.println(temperature + " Celsius " + " in Fahrenheit = "
+ convertedTemperature);
break;
default: // optional
System.out.println("Enterd temerature is Invalid");
break; // optional
}
}
}
/*OUTPUT
Enter 1 for Fahrenheit to Celsius
Enter 2 for Celsius to Fahrenheit conversion : 1
Enter temperature : 100
100.0 Fahrenheit in Celsius = 37.77778
*/
/*
Enter 1 for Fahrenheit to Celsius
Enter 2 for Celsius to Fahrenheit conversion : 2
Enter temperature : 37.77
37.77 Celsius in Fahrenheit = 99.986
