Question

Q Search ask #1 Creating a New Class 1. In a new file, create a class definition called Television. 2. Put a program header (comments or documentation) at the top of t // The purpose of this class is to model a television // Your name and today's date 3. Declare the 2 constant fields listed in the UML diagram. 4. Declare the 3 remaining fields listed in the UMIL diagram. 5. Write a comment for each field indicating what it represents 6. Save this file as Television java. 7. Compile and debug. Do not run. ask #2 writing a Constructor 1. Create a constructor definition that has two parameters, a manufacturer's brand 2. Inside the constructor, assign the values 3. Initialize the poweron field to false (power is off), the vo l ume to 20, and the 4. Write comments describing the purpose of the constructor above the method 5. Compile and debug. Do not run and a screen size. These parameters will bring in information. corresponding fields. channel to 2. header taken in from the parameters to the Task #3 Methods 1. Define accessor methods called getvolume, getChannel, getManufacturer, and getScreenSize that return the value of the corresponding field. Define a mutator method called setChannel that accepts a value to be stored in the channel field. 2. 3. Define a mutator method called power that changes the state from true to false or from false to true. This can be accomplished by using the NOT operator (!). If the boolean variable powerOn is true, then !powerOn is false and vice versa. Use the assignment statement poweron= !poweron ; to change the state of powerOn and then store it back into powerOn (remember assignment statements evaluate the right hand side first, then assign the result to the left hand side variable. 4. Define two mutator methods to change the volume. One method should be called increaseVolume and will increase the volume by 1. The other method should be called decreaseVol ume and will decrease the vol ume by 1. 5. Write javadoc comments above each method header Copyright © 2016 Pearson Education, Inc., Hoboken NJ
