[Solved] string & system.out.println and other functions doesn’t work [closed]

Question

EDIT: Classnames starts with a capital letter on Java

System.out.println();

In this case you can also use the Logcat console,

Log.v(TAG, your_value_var);

I give you anothers comments and advices.

First of all I think you should download a Java language paper from the beginning, there you would see and you could clarify all these doubts and you could solve all the language problems.

Secondly I would advise you to download the latest version of Android Studio, the one you are using is a bit old, maybe with bugs and others, Android Studio 3, made many changes for our benefit.

And finally I advise you here Stackoverflow when you ask a question is because we have tried to solve the problem in many ways by other ways and we have tried many times, things like these are not wonder here, but we see that you are very new, and that’s how we all started.

Welcome to the Community.

I hope it helps you improve.
