Hey all :D

[Goldjava]

What are some examples of tasks you'd tell the computer to do via the operating system interface?

Answer: Pretty much every single every day task. (ie. open Firefox, open minesweeper, type "hello")

is that right?

also fix this:

public class Cube 
{
   public static void main()
   {
      double height = 3.0;  \ inches
      double cube_volume = height * height * height; 
      double surface_area = 8 * height 
      System.out.println("Volume = " cube_volume);
      System.out.println("Surface area = " + surface_area;
   } 
 
 
I have so far:
 
 
{
   public static void main(String[] args)
   {
      double height = 3.0;  \ inches
      double cube_volume = height * height * height; 
      double surface_area = 8 * height 
      System.out.println("Volume = " cube_volume);
      System.out.println("Surface area = " + surface_area;)
   } 
}

You're on the right track for fixing that code. A couple small hints: What denotes a comment in Java? Also, what denotes the end of a line of code?

hi Goldjava,

Do you really dont know do fix this?? Or you are just kidding

Sure, those are examples. But also more basic stuff like "read the file xyz from the harddrive and show it to me".

also fix this:

We can help YOU fix it, if you like. We won't do it for you.

public class Cube 
{
   public static void main()
   {
      double height = 3.0;  \ inches
      double cube_volume = height * height * height; 
      double surface_area = 8 * height 
      System.out.println("Volume = " cube_volume);
      System.out.println("Surface area = " + surface_area;
   } 
 
 
I have so far:
 
 
{
   public static void main(String[] args)
   {
      double height = 3.0;  \ inches
      double cube_volume = height * height * height; 
      double surface_area = 8 * height 
      System.out.println("Volume = " cube_volume);
      System.out.println("Surface area = " + surface_area;)
   } 
}

Just follow what Laharl said - comments and command separators are what you have to fix.

By the way, please use [CODE] ... [/code] tags when posting code - it makes life so much easier. I've added them in this case.

Grades 11 and 12 I spent learning Java myself as my teacher sucked but now in 1st year university I forgot most of the easy stuff as it is 'too easy' if you know what I mean ;D

 public class Cube
{
public static void main(String args[])
{
double height = 3.0; // inches
double cube_volume = height * height * height;
double surface_area = 8 * height
System.out.println("Volume = " + cube_volume);
System.out.println("Surface area = " + surface_area);
}

You're close, but there's still one thing missing. I expect if you try to compile, the compiler will tell you what is going wrong...
