Hi Friend,

Try the following code. I will really help you.

import java.io.*;
import java.util.*;
class TemperatureConverter {
public static void main(String[] args) throws Exception{
System.out.print("Enter the Temperature: ");
Scanner input=new Scanner(System.in);
double temp=input.nextDouble();
System.out.print("Enter unit F or C: ");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String unit = br.readLine();
if((unit.equals("F"))||(unit.equals("f"))){
double c= (temp - 32) / 1.8;
System.out.println(c+" Celsius");
}
else if((unit.equals("C"))||(unit.equals("c"))){
double f=(temp*1.8+32);
System.out.println(f+" Fahrenheit");
input.close();
}
}
}

Thanks
