$\}$Last are the actual instructions from the assignment e$.$ Make sure there are no syntax errors then press the green Run button at the top of Eclipse. We see that one of our test passed and one failed. And in the Failure trace, we see the expected and the actual results.

f$.$ Fix the setProdPrice$($double$)$ method of the Product class so it handles values less than zero as described by our rules. Think about if you are not setting the value to check, so You need need to figure out where to add the change.$($Tips: Constructor$)$

g$.$ Make sure there are no syntax errors then press the green Run button at the top of Eclipse. Did both test pass this time?
