The program first reads integer recordingCount from input, representing the number of pairs of inputs

to be read. Each pair has a string and an integer, representing the recording's topic and duration,

respectively. One Recording object is created for each pair and added to ArrayList recordingList. Output

"Average recording duration: $",$ followed by the average duration of all the Recording objects as an

integer.

Enter the recording count: $3$

Enter pair $1$: Music $121$

Enter pair $2$: Medicine $85$

Enter pair $3$: Grammar $55$

Average recording duration: $87$

Note: the ArrayLIst has at least one element.

Create a Recording.java file:

public class Recording $\{$

private String topic;

private int duration;

public void setTopicAndDuration$($String newTopic, int newDuration$)\{$

topic $=$ newTopic;

duration $=$ newDuration;

$\}$

public int getDuration$()\{$

return duration;

$\}$

$\}$

Starter code:

import java.util.Scanner;

import java.util.ArrayList;

public class Recordings $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($System$.$in$)$;

ArrayList recordingList $=$ new ArrayList$()$;

Recording currRecording;

String currTopic;

int currDuration;

int sumDuration;

int recordingCount;

int i;

recordingCount $=$ scnr$.$nextInt$()$;

for $($i $=0$; i $<$ recordingCount; $++$i$)\{$

currTopic $=$ scnr$.$next$()$;

currDuration $=$ scnr$.$nextInt$()$;

currRecording $=$ new Recording$()$;

currRecording.setTopicAndDuration$($currTopic$,$ currDuration$)$;

recordingList.add$($currRecording$)$;

$\}$

sumDuration $=0$;

$/*$ Your code goes here $*/$

$\}$

$\}$
