A mutation is a slight change made to the program’s code to introduce a bug or regression. These altered code versions are called mutants. After the mutations have been inserted, the mutated versions of the program are run with the existing test suite. If tests fail, it means that the m...
it’s implicitly done by java runtime and we are not supposed to add a return type to it. If we add a return type to a constructor, then it will become a method of the class. This
The public Getters and Setters For example, in our Student class. To allow other classes toreadthe value of a private variablefirstName, we need to create aget methodcalledgetFirstName(). This is what we calledgetteroraccessor method. Other classes now can invoke these public accessor methods ...
