Problem
In the IDE to the left, the class MP3 is already defined. Use this class to do the
following things:
Create the class Podcast that inherits from H93
• Override the constructor such that the podcast has the following attributes:
• name - a string that is the name of the podcast
| title -a string that is the title of the episode
• length - an integer that has the length of the podcast in seconds
genre - a string that is the genre of the podcast
• date - a string that represents when the podcast was released to the public
Expected Output
Declare an instance of the Podcast class as shown below.
// add code below this line
Podcast p - new Podcast("Planet Money", "Hollywood"s Black List", 146e, "econon
// add code above this line
The table below shows the method calls (left) and the output (right). Your class
will be expected to work with all of these method calls.
Method Call
Return Value
System.out.println(p.displayName());
The name is Planet Money
System.out.printin(p.displayTitle());
| The title is Hollywood's Black List
System.out.printin(p.displaylength());
The length is 24 minutes and 20
seconds
System.out.printin(p.displayGenre());
