That is, all default constructors in public and protected classes should be turned into explicit constructor declarations with the appropriate access modifier.

The guidance manufacturers can then write software that invokes the methods described in the interface to command the car. Typically, a company sells a software package that contains complex methods that another company wants to use in its own software product. Right off the bat. Drawbacks Though this helps implement consistency throughout your software to a significant degree, it does not implement true interfaces -- but emulates them.

For example, a method that takes an index and uses an array internally should not be documented to throw an ArrayIndexOutOfBoundsException, as another implementation could use a data structure other than an array internally.
