Java

I need to convert a user inputted temperature from Celsius to Fahrenheit. this is what I have so far:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
 
    public static void main(String[] args) {
       privateMain(args);
    }

    private static void privateMain(String[] privateArgs) {
        System.out.println("Enter C or F <return>");
        BufferedReader in =
            new BufferedReader(new InputStreamReader(System.in));
        String type = null;
        try {
            type = in.readLine();
        } catch (IOException e) {
           
            e.printStackTrace();
        }
        if (type=);
        {
          //statements 
        }
        else
            //statements
        System.out.println("Converted is: " + temp);

       
    }
}

How do I take the input, read it as  Celsius or Fahrenheit, and convert it with the if statement? And i know I suck at programming, so you don't have to tell me

No singletons or factories.

Your teacher is going to fail you.

>No singletons or factories.

yes singletons or factories.

fix'd

#!/usr/bin/perl
input:
print "Enter temperature in C or F: ";
$t = <>;
goto input unless ($t =~ /(\d+)\w?(C|F)/);
$t = $1; $s = $2;
if($s eq "C") {
   $t = ($t * 1.8) + 32;
   print "Converted is: $t F\n";
} else {
   $t = ($t - 32) / 1.8;
   print "Converted is: $t C\n";
}

fantastic, helped tremendously

HOLY FUCK WHAT IS THIS SHIT?  This is what makes JAVA PROGRAMMERS look bad.

This thread is now about how java sucks

>>7
This thread is about how OP can't even read any of the dozens of books with exactly this example in to do his homework.

You can be an EXPERT PROGRAMMER if you use this link to learn a basic conversion.

I'm not trying to be mean or anything, but this is a really simple problem to solve. If you suck at this, chances are very high that you will also suck at solving much more complicated problems.

Java is the void of programming. Dohoho.

Someone write an ENTERPRISE QUALITY solution for him. Bonus points if he turns it in for marking.

Oh god...

I stopped reading when I saw that you weren't using stdin properly. Don't pass args into another ridiculous function. Just use args[0] to get the argument and do it all in main.

>>10
This.

java io.BufferedReader.import;
java io.IOException.import;
java io.InputStreamReader.public;

class Main public {
 
    static void main String(args[] privateMain) {
       args(private);
    }

    static void privateMain String(privateArgs[] System) {
        out.println.Enter("C or F return <BufferedReader>");
        in new =
            BufferedReader new(InputStreamReader System(in.String));
        type null = try;
        type {
            in = readLine.catch();
        } IOException (e e) {
          
            printStackTrace.if();
        }
        type (statements=);
        {
          //else
        }
statements
            //System
        out.println.Converted("is temp: " + importimimport);

      
    }
}

Use the state monad for referential pointer transparency (but don't overflow it, or it gets segfaulted).

I'm not a programmer, I hang out here just for fun, and I thought I'll check what I have learned from you guys. So, does that make sense? 

>>13
I, for one, applaud your effort.

shit

import java.util.*;
class Main{
 public static void main(String[] args){
  System.out.println("Enter temperature in C or F(e.g. 22 F): ");
  Scanner sc=new Scanner(System.in);
  double t=(int)sc.nextInt();
  if(sc.next().charAt(0)=='C')
   t=t*1.8+32;
  else
   t=(t-32)/1.8;
  System.out.println("Converted is "+t);
 }
}

dude,

main = getLine >>= \t -> return ((read t) * 9/5 + 32)

Dude.

WTF. Don't use fucking string concatenation. Instant fail. Use StringBuilders.

>>17
0 ºF = 32 ºC?

>>19
Duh retard.

>>19
Did you mean: 0 °F =  °C

>>18
Instant fail.  String concatenation is StringBuilders.

celsiusToFahrenheit = (32+).(%5).(9*)
fahrenheitToCelsius = (%9).(5*).subtract 32

God Bless Perl

>>23
one minor screwup though, \w should be \s
like a dumbass, I was thinking \whitespace

>>21
Incorrect.

15.18.1.2 Optimization of String Concatenation
An implementation may choose to perform conversion and concatenation in one step to avoid creating and then discarding an intermediate String object. To increase the performance of repeated string concatenation, a Java compiler may use the StringBuffer class or a similar technique to reduce the number of intermediate String objects that are created by evaluation of an expression.

For primitive types, an implementation may also optimize away the creation of a wrapper object by converting directly from a primitive type to a string.

>>25
PROTIP: His program isn't worth OPTIMIZING.

Everyone in this thread is just butthurt that the java solution >>16
is way easier to read(even w/o syntax highlighting), and around the same length as the perl solution. Oh yea and it doesn't have faggoty dollar signs in front of the variables names.
Java 1 Perl 0.

Your trolling needs work, try again.

Perl is ENTERPRISE quality.

>>17
main = print . (+32) . (*1.8) =<< readLn

#!/usr/bin/perl

my ($t,$conv,%conv) = ();
$conv{'C'}=sub($){32+1.8*shift};
$conv{'F'}=sub($){(-32+shift)/1.8};

print "Input temperature in C or F: " and $t=<> until $t=~/^(\d+)([CF])$/;
print "Converted is: ",$conv{$2}($1),"\n";

>>34
valid perl code

>>35
looks fairly straight forward to me

>>34
1. LPARAMS
2. FUNCTION POINTERS
3. REGEX EXPRESSIONS
4. FUNCTION POINTERS
5. ANONYMOUS FUNCTIONS
All to solve OP's trivial question.
Looks like ENTERPRISE QUALITY to me.

3. REGEX EXPRESSIONS
The full expansion is REGEX REGULAR EXPREGEX REGEXPREGULAR EXPRESSIONS

>>37
all of those things are the complete opposite of ENTERPRISE QUALITY.

module Main where
import Ratio

celsiusToFahrenheit = (32+).(%5).(9*)
