abstract and var-arg

• abstract methods must be implemented by a subclass, so they must be inheritable. For that reason:
• abstract methods cannot be private.
• abstract methods cannot be final.
• The native modifier applies only to methods.
• The strictfp modifier applies only to classes and methods.
• Methods with var-args 
• As of Java 5, methods can declare a parameter that accepts from zero to many arguments, a so-called var-arg method.
• A var-arg parameter is declared with the syntax type... name; for instance: doStuff(int... x) { }
• A var-arg method can have only one var-arg parameter.
• In methods with normal parameters and a var-arg, the var-arg must come last.
