I can run javac only at j2sdk1.4.1_02\bin folder. I can't run it outside.
I tried to fill the variables path like d:\j2sdk1.4.1_02\bin in system > Advance > Environments variables. But it was in vain.
Next, however I type the java codes exactly and correctly as the same as in the textbook, some can't be run and errors poped out like "NoSuchMethodError :main"
Help me, please.
