I’m using the Geany to do so. However, I was unable to compile the simple Hello World!. With some researches I found two reference links, being them:
https://www.guj.com.br/t/ola-mundo/51431/13
Javac does not compile. java .
With the first link, I was able to find the solution to the build error by adding -classpath . between the javac and Helloworld.java. However, searching on this, I bumped into the second link, however, I am using the Debian 10, and I couldn’t connect the points very well. If it’s not uncomfortable, I can clarify my (maybe) silly doubt, here?
See on the island of Geany:
The error presented:
philip@debian:~/Documents/java/java1$ javac Mundo.java
Mundo.java:4: error: cannot find symbol
System.out.printfln("Hello World!");
^
symbol: method printfln(String)
location: variable out of type PrintStream
1 error
Already in the tab of Compiler, he shows this error:
After I used the remote javac -classpath . World.java, in the current folder of my file .java it starts to compile normally, as if there were no mistake. Whenever I go to compile a file .java, should I do this procedure or is it some bad setup?
And what error occurs? And why are you using the
--classpathif it’s just a simple helloworld?. It’s important [Edit] and add a [mcve] of the problem, with a step by step of what you have already done and explain clearly and objectively where you failed.

Hello Philip. Do not use images to show codes and logs as images. Thank you for understanding.

Just for the record, There is no
System.out.printflnif you will not pass values with the parameters. It is a typo in your code. Just for the record, there’s no need to specify the -classpath if you’re not going to point to anything that’s going to be loaded.– Guilherme Nascimento
Yes, I’m sorry. I was testing printf and the println, ai in this example I ended up mixing the two kkkk. But even correcting, presented the same error.

Ah, I got it wrong again... it doesn’t exist at all, it was a "popular" site that had the wrong information. Well, to use
printfonly use if you need: https://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html#syntax / if you do not useSystem.out.println("Hello World!");– Guilherme Nascimento
Okay, thank you. But could you tell me what this is for classpath. ?
