what are the uses of assert keyword?

Hi Sarje,

An assertion is a statement in the JavaTM programming language that enables you to test your assumptions about your program.

For example, if you write a method that calculates the speed of a particle, you might assert that the calculated speed is less than the speed of light.

The assertion statement has two forms.

a) assert Expression1 ;

b)assert Expression1 : Expression2 ;

Expression1 is a boolean expression., Expression2 is an expression that has a value


Use this version of the assert statement to provide a detail message for the AssertionError.

The system passes the value of Expression2 to the appropriate AssertionError constructor, which uses the string representation of the value as the error's detail message.

Thanks & Regards,
Riju.
