DUDE!! You just saved my day! I just started doing java and never used the cmd. This class I'm in doesn't even show you how to use command prompt to find or access files. It just assumes that you know how to do it. I been searching youtube this whole time and you give the BEST and SIMPLEST way to do it. NICE JOB MAN!

7:00 For source files containing packages 8:00 -d flag for package folders 8:20 dot flag - represents folder then give the name of the source file 8:30 example of the above 8:48 Overview of what needs to be called 9:30 Running the program in the terminal 9:55 For programs containing sub-packages - use full stop to denote a sub-folder followed by its name e.g. one.two = top-level folder called 'one', sub-folder called 'two'.

Hi, my java program has those import packages such as "import java.io.FileInputStream; import java.io.FileNotFoundException;" and some custom SAP frameworks designed by DEVs to perform certain tasks. what could be done in this case, if we need to compile java program with this packages.

So i have a executable file on a flash drive that needs a password to open. Once open it has a java program file (.java), is there a way to run that file through cmd? Have been looking around and haven’t found much. Thanks

[@snoopie51]

Nice video! But everything worked up until I got a class not found error message?

[@ashwinsights3952]

Hey the video is awesome :) and also i have an doubt that why we r putting -d ??

[@LearningLad]

thanks By default, javac will output the class file in the same directory as the source file. we can change this behavior by using the "-d" option. It will make javac to output the class file into the specified directory

[@ashwinsights3952]

@@LearningLad thanks for clearing this doubt :D

[@christy4217]

Nice video

[@LearningLad]

Thanks

[@goldenraisins]

I got an error message that says "'javac' is not recognized as an internal or external command, operable program or batch file." Does that mean I don't have javac installed? I am able to run programs just fine on my IDE, so I'm reluctant to think that's what it is. I would appreciate your help!

[@LearningLad]

If Java is installed then you need to set the path environment variable

[@nicolaslacortiglia9710]

It says javac isn't recognized as an internal or external command when I try to use it

[@LearningLad]

after installing java make sure that you have set the path environment variable

[@jeddf.torrecampo5851]

Why i am getting 'javac' is not recognize? Pls help

[@LearningLad]

If Java is installed properly then check the path environment variable
