I follow the dummies book and i written :

import java.util.Scanner;

class EchoLine {

public static void main(String args[]) {
Scanner keyboard = new Scanner(System.in);
System.out.println(keyboard.nextLine());
keyboard.close();
}
}

The error shown :

Must declare a named package because this compilation unit is associated to the named module 'MyNewProject'

The console tab shown :
Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: C:\Users\Leow\myfirst-eclipse-workspace\MyNewProject\bin
Caused by: java.lang.module.InvalidModuleDescriptorException: EchoLine.class found in top-level directory (unnamed package not allowed in module)

Anyone can advise what wrong ?

Thanks

Yes, You need to place your class file in a package, default package does not work with modular projects.
