3.6 Explain what an overloaded method is and give an

example.

3.7 Explain what an overridden method is and give an

example.

3.8 Explain what accidental overloading is and the

preferred Java method for preventing it.

3.9 If an overridden method in a subclass needs to call the

overridden superclass method, how is this accomplished?

3.10 True or False? It is legal for a method in a class to

overload another method also in the same class. Explain.

3.11 True or False? It is legal in a class for a method to

override another method also in the same class. Explain.

3.12 True or False? It is legal in a subclass for a method to

overload a method in the superclass. Explain.

3.13 True or False? It is legal in a subclass for a method to

override a method in the superclass. Explain.

3.14 True or False? It is legal in a superclass for a method

to overload a method in a subclass. Explain.

3.15 True or False? It is legal in a superclass for a method

to override a method in a subclass. Explain.

3.16 In a subclass constructor, the superclass default

constructor is called automatically before the statements of

the

subclass constructor begin executing. Suppose we wish to

call a different superclass constructor (i.e., not the default

constructor) from the subclass constructor. Explain how

this is accomplished and give an example.

3.17 Explain how an abstract class differs from a concrete

class.

Solution

3.6 )What is method overloading in Java :

Method overloading in Java is a programming concept

when programmer declares two methods of the same name

but with different method signature, e.g. change in the

argument list or change in the type of argument. method

overloading is a powerful Java programming technique to

declare a method which does a similar performance but

with a different kind of input. One of the most popular

examples of method overloading is System.out.println()

method which is overloaded to accept all kinds of data

types in Java. You have println() method which takes

String, int, float,double or even char in output. All of those

methods are collectively referred as an overloaded method

in Java.

The difference between method overloading and overriding

is also a popular Java interview question. In next section,

we will some important points about method overloading in

Java and then a simple example of how to overload a

method in Java.
