110 Pointsi followed the instruction but it just could not printf ?
hi all, i am a newbie and i am confused: i did type at upper screen as follow:
[[[```java import java.io.Console;
public class Introductions {
public static void main(String[] args) {
Console console = System.console();
// Welcome to the Introductions program! Your code goes below here
console.printf("hello, i am noob");
} }
however when i type at lower window as follow:
[[[treehouse:~/workspace$ java introductions.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
treehouse:~/workspace$ javac introduction.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
javac: file not found: introduction.java
Usage: javac <options> <source files>
use -help for a list of possible options
treehouse:~/workspace$ -help
bash: -help: command not found
treehouse:~/workspace$ javac introductions.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
javac: file not found: introductions.java
Usage: javac <options> <source files>
use -help for a list of possible options ]]]

Is this the code that you wrote for the challenge, Strings, Variables, and Formatting? Or are you writing this freely within Workspaces?

- when you compile, use "javac Introductions.java" NOTE THAT "I" in Introductions.java is uppercase.
- Next step is to run the code, use "java Introductions" NO NEED TO USE .java in the end or "javac"
