how to use assert

Eric

I would like to use the assert keyword, but my compiler doesn't seem to
recognize it. It's also not in the api (only the AssertionError is).

What am I missing? I'm using 1.4.1_05 on windows.

Thanks

From Sun's documentation
(http://java.sun.com/j2se/1.4.1/docs/...ml#compiling):

"Compiling Files That Use Assertions
In order for the javac compiler to accept code containing assertions,
you must use the -source 1.4 command-line option as in this example:

javac -source 1.4 MyClass.java
This flag is necessary so as not to cause source compatibility
problems. "

You also need to enable assertions when you start up the JVM with the -ea
flag
'java -ea MyClass'
