Hello,

Here are my error messages from javac -

C:\j2sdk1.4.2_02\bin>javac xx.java
xx.java:125: <identifier> expected
Vector<Object> king =new Vector<Object>();
^
xx.java:225: '(' or '[' expected
ArrayList<Object> queen = new ArrayList<Object>();
^
2 errors

Without the <Object> it compiles fine - I am on dialup so do I really
have to get 142-08?

Thanks,

LM

Generics (eg. Vector<Object>) are a feature of 1.5.0 (aka java 5.0) and
are not available in 1.4. So, yes, if you want those features you have
to update (to 1.5).

ICBW, but isn't it simply "java 5", with no revision? I think it's one of
those marketing hoohah moments. Very confusing from the get-go. Like
having "Java 2" with jdk revs in the 1's.

http://java.sun.com/j2se/1.5.0/docs/relnotes/version-5.0.html

"Both version numbers "1.5.0" and "5.0" are used to identify this
release of the Java 2 Platform Standard Edition. Version "5.0" is the
product version, while "1.5.0" is the developer version. The number
"5.0" is used to better reflect the level of maturity, stability,
scalability and security of the J2SE."

Of course, the -source parameter to javac accepts 1.5 and 5.

Thanks for the link. Clears it up a tad.

The really funny bit is if they do a "Solaris" next, and use 5.1 for
1.6.0.

Yes. The <Object> indicates the use of generics availible only in 1.5 or
higher.
