Java Programming
1.What
are the benefits of inheritance? Explain the various forms of inheritance with
suitable code segments.
Ans.
Inheritance are code reusability and readability. When child class inherits the
properties and functionality of parent class, we need not to write the same
code again in child class. This makes it easier to reuse the code, makes us
write the less code and the code becomes much more vvvIts Half solved only

Ans.. The
traveling salesman problem consists of a salesman and a set of cities. The
salesman has to visit each one of the cities starting from a certain one (e.g.
the hometown) and returning to the same city. The challenge of the problem is
that the traveling salesman wants to minimize the total length of the trip.
The traveling
salesman problem can be described as follows:
