The code is supposed to promt the user to enter the temp,
then output the temp in degrees C and F, and format in to two decimal places.
I'm having trouble filing in the blanks.:(

The code is supposed to promt the user to enter the temp,
You seem to have that working okay.

then output the temp in degrees C and F, and format in to two decimal places.

System.out.printf("num = %.2f %n", F,C);
// try
System.out.printf("F = %.2f  C = %.2f%n", F, C);

I'm having trouble filing in the blanks
Which blanks now?

[tool_010]

I feel so pathetic, cause this code is so simple. THANKS FOR HELPING ME!!!!!
Should there be any other statements for C?
The format to dec looks good but is the output for C and F right or do I need something else?
GD. I suck @ this.

Here's the syntax error that I'm getting.

Is there a file named Celsius.class in the folder where you are entering the java command? The java command can't find it.

[tool_010]

No sir. I created this class.

[tool_010]

class name

[Norm]

What is the full filename of the class file you created?

[tool_010]

Celsius.java

[Norm]

There is confusion between source and class files.
Celsius.java is the source file, not a class file.

To execute it you need first to compile it with the javac command:
javac Celsius.java
If there are no errors, javac will create Celsius.class.
Then you can execute it by entering: java Celsius

[Supamagier]

and if it can't find javac... use

"path/javac"

, including the ""
