import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// TODO code application logic here
Scanner userInput = new Scanner(System.in);
String name;
System.out.print("What is Your Name : ");
name = userInput.next();
System.out.printf("Your name is %s", name);
}
}
Works fine with no package and a renamed class.

Try changing the names and rebuilding it.

74,902 PointsExcuse me, but removing the class is not the answer!
As mentioned below java is a reserved identifier, it would be like using any keyword such as public, or static, etc

57,712 PointsHi Lewis,
Which class got removed?
I suggested renaming the class as the initial code sample had called it
Javawhich, as you say, is a reserved word. Is that what you are referring to?Cheers,
Steve.

74,902 PointsLewis Cowles
74,902 Pointswell both the package and the class are using reserved word
javaso it's applicable to both mateSteve Hunter

57,712 PointsIndeed - I didn't know if this was command line or IDE-based. IntelliJ didn't insist on a package so my code snippet didn't have that and I renamed the class. I think that got Tony up and running with whatever he wanted to do.
