used as an identifier

test145.java:7: not a statement
assert true;
^
test145.java:7: ';' expected

Hi Shekhar,
Please checkout pages 260 & 261 in K&B book. It helps.
From text...
Remember, assertions are diabled by default in 1.4, both at compile time and run time.
Hope this helps.

Try compiling and running your class with the -ea or -enableassertions parameter. Compiler sees this like

x true;

HTH,

Hi Sekhar
When you run your program on sdk 1.4 or above, u have a possibility to use assertion, but you should diasable them, 'cause by default they are not!
in compilation you should tape
> javac -source 1.4 Example.java
and for running
> java -ea Example.class
hope u understood me!
