public class Assert extends Object
Utility to make asserts.

In most case this asserts verify if the object is null. There are a variety of methods that throw differents exceptions.
One of the thrown exception is AssertException, but this is not mandatory.

If some of this methods throw exception this is usually due to a software error, normally a exception that the user-programmer has not fullfilled the contract.
The messages does not have to specify the place where contract is break or which contract is broken. The trace (that always is printed) indicate the place and the exception class. In the doc of method that throw the exception you can obtain more info about it.
The names and behaviour match with JUnit, the difference is the thrown exceptions.
