Program 1.1

i am stragling to create a working directory, i've tried to do this: Creat a Path

MyDirectory;c:\Program Files\Java\jdk1.6.0_21\bin

The following program was stored under MyDirectory with the name SimpleProgram.java

Quote

public class SimpleProgram {
public static void main(string[] args) {

System.out.printIn("A proverb: ";

String proverb = "Practice makes perfect: ";
System.out.print(proverb);

int characterCount = proverb.length();
System.out.printIn("The proverb has " + characterCount + "characters.";
}
}

javac does compile ok and java does run ok

But if i try to type: javac SimpleProgram.java
the output is:
javac: file not found: SimpleProgram.java
usage: javac <option> <source files>
use -help for list of possible option

WHERE do i go wrong?

Sorry i've got it, i was not writting it in full. I was suppose to type:
cd c:\MyDirectory \ javac SimpleProgram.java
