Cant compile/run java program

seamore · 04-14-2022, 11:17 PM

I just download and expanded a jdk

tar xzvf jdk-8u311jdk-8u311-linux-x64.tar.gz

I went into the bin directory and tried to run the standard hellow world java program

When I ran javac* helloWorld.java I got the message “bash: .javac: cannot execute binary file”

All the files in the bin directory are -rwxr-xr-x

helloWorld.java:

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello world!");
}
}

You need to set JAVA_HOME and PATH.

Your posts contain no information, dropping in an error message is not enough to help you.
So please tell us exactly what did you execute, what's happened. Please post full output, not only a few lines.

Or just look for pages on the net containing your error message (cannot execute binary file), like this:

As a start:

Code:

set | egrep 'PATH|JAVA_HOME'

Did you literally put an asterisk after the javac? That looks wrong.

Thank all of you for the help.
I installed a jdk one version below and things worked.
