Java Java Basics Getting Started with Java Receiving Input

console vs. system

Just start the Java track.

I noticed that they teach you console.printf("Hello Word") But, I download eclipse and it does not recognize it. It uses System.out.print("Hello World").

My question is:

  1. "Are the Java commands different using different programs?"
  2. "Is it an eclipse format?"
  3. "What is the correct one?"

That is known thing, both here:

And in Stack overflow detailed explanation why Console can't be used in any IDE:

Since you haven't passed any code or errors, I just inferred that is the problem that you have.

So in two words: do not use Console object in IDE, when you press run button.

You have to use BufferedReader or Scanner for that.

For why questions read more in forums above, it is pretty explanatory...

BTW, before digging into Eclipse, I suggest learning Intellijidea, because if you are on Java Track, soon you'll get to 'Local DEvelopment Environments' Course:

where Craig will teach a lot of helpful tricks. No such great tutorial you will find ever on the web, at least my opinion.
