brand new to eclipse and trying to follow the 'dexter' videos on youtube....

Q1: when i create a scrapbook and try something simple like
int a:
a= 5;
and then i try to inspect a i get error
a cannot be resolved to a variable

what am i doing wrong? i didnt define any classes so i dont think i need to import a package

question 2: if i import a package into the scrapbook ... can i see this ? how do i know I did it?

thx

Question 1: did you select both lines of code before doing Inspect...? It will evaluate whatever you have selected, so if you only selected the assignment line, it doesn't know about the first line where you declared a.
Question 2: The set of imports for a scrapbook page are configured (and viewed) by right-clicking in the scrapbook and choosing Set Imports... from the popup menu.

thanks Eric!
yep.. i see that i have to select all of the text (mulitple lines) that apply to creating the variable if i want to use the inspection button

is the purpose of inspect .. just to see the value of only 1 variable (ie the last variable typed without a ";" , ie. does inspect have a very limited value when coding/debugging?

for example... if I select this text to try to inspect the values of a and b I get an error because I guess the program fails on the line that just has 'b'?

int a = 5;

int b = 2;
b
a = a * 10;
a
