i'm trying to create J2ME app with J2ME sdk 3.0 with command line and i'm confused on how to compile and preverify my source code.can anyone show me how to please ?
Pretty much all IDE's allow you to run and compile the code inside them, rather than having a separate pipeline to edit the text files, compile them and run them.
For example, in IDEA you have a "Run" menu that you can use to access all those functionalities.
I suggest that, especially if you are inexperienced, you switch from a "manual" process using separate tools (text editor, compiler, runner) to a more unified one, that will sort out most of the details for you letting you focus on the writing of the code / logic.
