Simple answer required

I have had troubles with getting messages such as:

C:\Java>java Temperature

Exception in thread"main" java.lang.NoClassDefFoundError: Temperature

I have found that using the following code I can type in java Temperature

C:\Java>set classpath=%classpath%;.;

The only other way I have found to run my programs is to use the code:

C:\Java>java -cp . Temperature

My question is do I have to use the "set classpath" or the " -cp . " everytime I open the command prompt?

Please help

Thank you

Jonathan.
