what is the java code to convert feet into meters? we have a homework problem that we need to make a program that u input feet and it converts to meters

i just need the code that identifys the input number and converts it then System.out.println (whatever the value is)

There is actually a built in class that allows you to do this, it is called.

convertFeetToMeters(feet) so just call that with the argument feet.

I assume you know how to do input output.

just find what the ratio is and multiply the input by that number

ie:

1 foot = 0.3048 meters

1 meters = 3.2808399 feet

I'm not sure if java has some spiffy built in conversion funtion since I've never coded in java......

huh what? im gettin compile error

heres what i have so far, dont i have to identify the value of whats being inputted?

public class second {

public static void main (String[] args){

public static final double feet2meters = 0.305;

System.out.println(output)

}

}

huh what? im gettin compile error
illegal start of expression

public static final double feet2meters = 0.305;

not sure there, like I said I've never programmed in java but it's probably just syntax... or some lame rule about doubles.... besides you don't need a double for that, you are wasting memory //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I dont believe that you can have main inside of a class. take out that class and try to recompile, also make sure you have your imports correct. I have not programmed in jave in a long time, sorry. You will learn quick to not like it.

i already dont like it //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

yah I ditched CS because it was too much of a PITA... I still know 5 languages but I'm self taught and I'm sure my code would make a professor cry.... but then again I never want to be someones *****... I want to be the boss //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

what I would do is just take a working program, gut it and drop in the code to get the input and hard code the multiplication..... quick and dirty....

also need a ; after your output line...

will i have to learn this crap if i choose to major in compter science?

Definitly, I think most colleges make you start out with Jave then you move to C++(which is great), and you will learn Assembler(Which is a pita but useful.)

how hard is learning computer science? im great with computers i can build them if u give me the parts and i can maintain a computer so it has absolutely no viruses and no bullshit programs you dont need installed. given that much information, should computer science be a breeze for me? im debatnig between majoring in Real Estate (to become a real estate appraiser), computer science (to become a software engineer), or engineering (because i love cars).

CS is a lot of math and logical thinking, its not about being able to take apart and put together a computer.. It involves a lot of computational theory and discrete math. Don't go into CS unless you are very comfortable with logic and math.

That code is meaningless, you haven't defined what that variable output is. Infact I don't even know where you are going with that code, where is the input coming from? The command line?

you want a 2 yr degree in like computer repair or something, NOT computer science...
