The Java compiler type-checks the arguments to each varargs method to ensure that the arguments are of the same type or object reference. However, the compile-time checking is ineffective when two specific parameter types are used: {{Object}} and theor generic type {{T}} parameter types are used \[[Bloch 2008|AA. Bibliography#Bloch 08]\]. Another requirement for providing strong compile-time type checking of variable argument methods is to be as specific as possible when declaring the type of the method parameter.
