I'm trying to get started in this Java program:
1. Define the double variables name test1, test2, test3
2. Assign values three test scores to test1, test2, test3 (for example 98, 95, 97)
3. Calculate the average or test1, test2 and test3
I started with:
double test1 = "98"
double test2 = "95";
double test3 = "97";
and the program already tells me something is wrong.

it's a double. i.e. numbers with decimals trailing. 98 should be 98, not "98" it should be like this: double test1 = 98;

correct, the "" mean it is being defined as a string. but you want a double integer value. so you do not need the "".

I always like to go slow with them :P. Make them learn it. technically we should also say 98.0d is the standard. Only Double, Floats, and Longs really are classified... You can find it here! http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

Additional question: I got program without errors, but my average displays 96.6666666667. How can I make it only display 96.7? I know how to do it in C++, but not in Java.
