I need help with this.

[onox37]

I need to know what it does and how to finish it. My friend gave it to me for a challenge because I told him I knew javascript and I have no idea what it is.

 

package ConsoleApplication1;

import java.math.*;

import java.util.*;

import java.io.*;

 

/**

* Summary description for Program

*/

public class Program

{

public static void main(String[] args)

throws IOException

{

BufferedReader console = new BufferedReader(new InputStreamReader(System.in));

String input = console.readLine();

int i = 0;

String out = "";

int cof;

int power;

int l = input.length();

while (i <= l - 1)

{

 

cof = 0;

power = 0;

if (input.charAt(i) == '+')

{ out = ""; }

 

if (input.charAt(i) == 'x')

{

//shasfjdlkvhasjlkvhjklhlvhjlhvjashvjklhalashdvjklasdhvjklhghg

//System.out.println(out);

 

if (out == "cos")

{

System.out.print("-sin");

}

//asvdhjkasghdvjgvvhgggdjklshdjklsdhfjklshdfjklasdhflsdhflkah

try

{

cof = Integer.parseInt(out);

}

catch (NumberFormatException e) { }

 

i++;

 

if (input.charAt(i) == '^')

{

out = "";

i++;

while (input.charAt(i) != '+' && i <= l - 1)

{

out += input.charAt(i);

i++;

 

}

 

power = Integer.parseInt(out);

cof *= power;

power -= 1;

System.out.print(cof);

System.out.print("x^");

System.out.print(power);

if (i != l - 1)

{ System.out.print("+"); }

 

}

else

{

System.out.print(cof);

if (i != l - 1)

{ System.out.print("+"); }

}

out = "";

 

}

 

String f = "1";

int g;

 

//try

//{f+=input.charAt(i);

//g=Integer.parseInt(f);

out += input.charAt(i);//}

 

//catch (NumberFormatException e){}

 

 

i++;

 

 

}

}

}

My friend gave it to me for a challenge because I told him I knew javascript and I have no idea what it is.

 

Why did you take the challenge, if you knew nothing about the code your friend was challenging to complete? That wasn't very smart was of you to do. ???

 

This looks allot like vb.net to me; but I could be wrong - it's been a long time since I had that class in college.

 

Good Luck With Your Challenge!

hey dude, that is java not javascript.

 

what is the prize for that challenge? Haha...

[phpQuestioner]

I though it could possibly be java, but I wasn't sure; never learned java.

[jos.]

I am pretty sure that It is a primitive calculator..... Maybe not... I think it just spits out what ever you put in ... tell you friend that he should learn better variable naming practices.
