Question

Pick a pair of concrete classes in the JDK in a parent-child relationship and discuss a few polymorphic and/or overloaded methods.

Do not use Object as the parent class - it is too trivial to address the issues to be addressed here, and in any case, Object is the final parent of all classes in Java.

Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

1)you can take instance of JButton magnificence javax.swing.JButton.java

2) AbstractButton.java is parent class for JButton(javax/swing/AbstractButton.java)

3) In JButton class there are 2 overloaded features

(Funtion with equal call and special parameters)

those are 2 constructors (Initilization of class)

//JButton Constructor with Button textual content and Button background Icon
public 1x1.gifJButton(String text, Icon icon) {

}

//JButton Constructor with on Button (Default history can be used)
public 1x1.gifJButton(String text) {

}

4)The above I defined is assemble time polymorphism (equal approach names)

5)And also RunTimeException.java and ArithmaticException.java are in Inheritence relationship

Kindly revert for any queries

Thanks.
