Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;
class Converter {
Scanner input=new Scanner(System.in);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String unit="";
public void convertTemp(){
double temp=input.nextDouble();
System.out.print("Enter unit F or C: ");
try{
unit = br.readLine();
}
catch(Exception e){}
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();
}
}
public void convertDistance(){
double dis=input.nextDouble();
System.out.print("Enter unit KM or Miles: ");
try{
unit = br.readLine();
}
catch(Exception e){}
if((unit.equals("KM"))||(unit.equals("km"))){
double miles = dis * 0.621;
System.out.println(miles+" Miles");
}
else if((unit.equals("Miles"))||(unit.equals("miles"))){
double km = dis/ 0.621;
System.out.println(km+" KM");
input.close();
}
}
public static void main(String[] args){
Converter convert=new Converter();
System.out.print("Enter the Temperature: ");
convert.convertTemp();
System.out.print("Enter the Distance: ");
convert.convertDistance();
}
}

Thanks
