Document

Validate an argument, throwing IllegalArgumentException if the test result is false.

This is used when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.

 Validate.isTrue( (i > 0), "The value must be greater than zero"); Validate.isTrue( myObject.isOk(), "The object is not OK");

For performance reasons, the message string should not involve a string append, instead use the #isTrue(boolean,String,Object) method.
