Public class Channel { Private String description; Private String imgPath; Private String audpath; Private MediaPlayer mediaPlayer; Public Channel (String Description, String imgPath, String audPath) { This.desc = description; This pathToImage = imgPath; This.audPath = audPath; mediaPlayer = new MediaPlayer(); } } Problem Solving 2 A channel is created with the following attributes: о A description like "VOLTRON: DEFENDER OF THE UNIVERSE". • ○ The path to an image file that is a still image from the show. о The path to an audio file like a .WAV or .mp3 Each channel should create its own Media Player that can be used to control playback of its media. Use the space to the left to define a Channel class. Include fields and a constructor. ○ You do not need to worry about any other methods at this time. Problem Solving 3 The Channel class should provide any methods necessary for controlling the playback of its audio clip, including: • A method to play the clip. • A method to stop the clip. • • A method to increase the volume by 0.1 up to a max of 1.0. A method to decrease the volume by 0.1 down to a min of 0.0. • A method to get the current volume (a value between 0.0-1.0 inclusive). Use the space to the right to implement the last two methods in your Channel class. The Media Player provides methods that you will find useful: • setVolume (double v) public void decreaseVolume() { double minVolume = 0.0; double volAfterDecrease = mediaPlayer.getVolume() - 0.1; double minOfBoth = Math.min (minVolume, volAfterDecrease); mediaPlayer.setVolume (minOfBoth); } public double getCurrentVolume() { return media Player.getVolume(); } • getVolume () You may want to review the online documentation for the MediaPlayer. } public void changeChannel (int channelNumber) { Problem Solving 4 Assume that you have the following fields: private Channel () channels; private Channel currentChannel; Write a method in your main GUI class that, given a channel number, changes to the specified channel. • If it's the same channel that is currently playing, don't change it! • Otherwise: ○ Stop any audio that is currently playing. о о о 00 о Play the audio for the new channel. Display the channel number and description somewhere in the GUI. Display the still image somewhere in the GUI. Challenge: Set the volume on the new channel to the same as the last channel.
