Java

The code from the Java basics does not work in Netbeans IDE.

The console commands e.g. console.printf() and System.console() do not have red lines under the code but when I try to run it, an error comes up saying that the .printf method has a null value. Since it doesn't work I'm using the System.out.println() method instead, but I was wondering why the code doesn't work. I've copied it exactly as it is in the video but it doesn't work.

A quick google search told me that

Bug 111337 – java.io.Console not supported - NetBeans https://netbeans.org/bugzilla/show_bug.cgi?id=111337 תרגם דף זה 1 2007 - In both NetBeans 5.5.1 and 6.0 M10, java.io.Console is not supported. However ... from both JDK 1.7.0b16 and JDK 1.6.0_02b5: import java.io. Bug 235334 – cannot run the console from within Netbeans https://netbeans.org/bugzilla/show_bug.cgi?id=235334 תרגם דף זה 17 2013 - Console; import java.io. ... SocketException; import java.util.logging. .

But the high level answer is that you need to import the console first before using it.
