assertions doubt

[Lucky J Verma]

I have basic doubts in assertions.


1.
Can we use assert as an identifier in java 1.4 .if we dont enable it .
2. In K &B chap 5 ,pg 378
it says ,with javac -source 1.4 abc.java ,asertions enabled .
but i beleive it means ,telling Compiler to compile or code with 1.4 compiler ,in which assertions are Keywords.
then how is this the way to enable assertions at compile time.
and in java 1.5 ,assertions are always keyworkds.

Hi

From 1.4 assert is a keyword.So irrespective of whether assertions are enabled or not,you cannot use it as an identifier.

To enable assertions
us java -enableassertions or java -ea

Just saying javac -source 1.4 does not enable assertions.

If you use source other than 1.4 or 1.5 alone,you could use assert as an identifier.

Please correct me if am wrong.

Thanks
