Cannot find symbol class, but why not?

[gnng]

Newbie to Java - I created a new class called Temperature and now am trying to write a class called TempDemo to test everything - but can't get past "linking" the two programs. I think I followed the format of my other programs by:

1) Naming the first program

public class Temperature

2) Using the following to tell the second program to go to this class

Temperature t = new Temperature();

When I do this it comes back with an error "cannot find symbol class Temperature". Can't figure this out! Here is the complete code. Thanks in advance for any help you can provide. Gary

FIRST PROGRAM

public class Temperature
{
	private double tempValue;
	private char scale;


	//constructors

public Temperature(double tempValue)
{
	this.tempValue = tempValue;
	scale = 'C';
}

public Temperature(char scale)
{
	 tempValue = 0;
	 this.scale = scale;//should this be C?
}

public Temperature(double tempValue, char scale)
{
	 this.tempValue = tempValue;
	 this.scale = scale;
}

public Temperature()
{
	 tempValue = 0;
	 scale = 'C';
}

//mutators or setters
 public void setTempValue(double tempValye)
	 {
	 	this.tempValue = tempValue;
	 }

public void setScale(char scale)
	 {
	 	this.scale = scale;
	 }

public void setBoth(double tempValue, char scale)
{
	this.tempValue = tempValue;
	this.scale = scale;
}

//getters

public double getTempValue() //not sure I need this but put it in so boolean works
{
	double tempValue = 0;
	return tempValue;
}

public double getTemperatureF()
{

	 double degreesF = (9 * (tempValue / 5)) + 32;
	 return degreesF;
}
public double getTemperatureC()
{

	 double degreesC = 5 *(tempValue - 32) /9;
	 return degreesC;
}

//boolean needed to 1) test whether two temps are equal, and 2) test if one temp is less han the other

public boolean equals(Temperature otherTemperature)
{
	return(this.getTempValue() == otherTemperature.getTempValue());

}
public boolean isLessThan(Temperature otherTemperature)
{
	return(getTemperatureF() < getTemperatureC());

}

public boolean isGreaterThan(Temperature otherTemperature)
{
	return(getTemperatureF() > getTemperatureC());
}

//toString

public String toString()
{
   return tempValue + " " + scale;
}
}

SECOND PROGRAM (HAVE NOT GOTTEN VERY FAR, I KNOW)

import java.util.*;


public class TempDemo
{

public static void main(String[] args)
{
	//use all of the constructors
	Temperature t = new Temperature();

}

}

Have you compiled the first program before using it in second class.

also make sure, both programs are in same directory.

Don't I feel like an idiot! It wasn't working because I took this project to school on a flash drive and it was saving the first program to that, and since I started the second program at home it was saving it on the hard drive. Like I said, total idiot!
