Need some help with OSX Java (Terminal)

I've recently switched to a mac book and am attempting to compile and run some of my old java scripts to figure out how everything works with the mac and terminal.

Anyhow while I use the javac command I am getting tons of errors. Very basic simple coding is giving me upwards of 100 errors for basic loops. What am I doing wrong?


Here is the my command:

Matthew-lastname-MacBook-Pro-2:~ Matt$ javac Documents/Professional/java/LabOneAssignment.java
Documents/Professional/java/LabOneAssignment.java:20: illegal character: \0

^
Documents/Professional/java/LabOneAssignment.java:20: illegal character: \0

^
Documents/Professional/java/LabOneAssignment.java:20: illegal character: \0

^
Documents/Professional/java/LabOneAssignment.java:20: illegal character: \0

(this error x 100 with ^ carrot gradually moving over)


Very very basic code I'm testing this with:


/**
* This is the main method for this class
*
*
* @author XXXXXX
* @param args
*/

public class LabOneAssignment {
public static void main(String[] args) {
int one;
String name;
one = 25;
name = "Fred";
System.out.println("The integer is: " + one + "\n"
+ "The name is: " + name);
}
}

here is some more info:


machine:~ Matt$ java -cp ./ testcheck.java

Exception in thread "main" java.lang.NoClassDefFoundError: testcheck/java

Caused by: java.lang.ClassNotFoundException: testcheck.java

would it make a difference if the files were written on windows in jEdit and then transferred to OSX? The path still points to them unless its an issue with the text file itself...

I don't think it likes your "\n". Perhaps it's treating it as an escape character.

I'm at a loss, I tried to compile this simple code as well:

machine:~ Matt$ javac Documents/java/testcheck.java

/**
* This is the first class in the first lab of the first semester of Java!
*
* @author XXXX
*
*/
public class testcheck {

/**
* This is the main method for this class
*
* @param args
*/
public static void main(String[] args) {

System.out.println("Hi there!");

}

}


Resulted in the same errors as above...

Since trying this on my mac book I have gotten errors such as this, but compiling / running with DOS has worked as intended.

additional info:

All scripting was done in jEdit

machine::~ Matt$ java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)

I'll try to move code to eclipse and compile it through that and see if it will bipass this all but I really have no idea why this isn't working.

It's as if I don't have the development kit, but with java native on OS X I should have everything I need?

I have figured out the problem. I originally wrote these codes in jEdit (Windows). I transferred the files to OS X and opened them, edited them and even re saved them overwriting the previous files. It was not until I made completely new files and cut the code, pasted it into a word pad and then into jEdit.

Just a weird oddity I guess... several hours later...

Windows machines add different line separators than unix/mac (\r\n vs \n)...pass the same file onto a mac and the file might not behave properly (this can get to be serious pain in other situations - such as writing a perl/php script on windows to transfer and run on a linux server)

On other OS's based on linux/unix (like OS X is) I've used the command dos2Unix to remedy this.

Not sure if that command comes standard with OS X or not, but if not you can probably add it.
