public final class Assert

extends java.lang.Object

Assert is useful for for embedding runtime sanity checks in code. The predicate methods all test a condition and throw some type of unchecked exception if the condition does not hold.

Assertion failure exceptions, like most runtime exceptions, are thrown when something is misbehaving. Assertion failures are invariably unspecified behavior; consequently, clients should never rely on these being thrown (and certainly should not being catching them specifically).
