Computer Science 1- Java

Please include all the code for my reference. This is my set up. PLEASE add comments for easier understanding. Paste the whole code as plain text as the answer. Only make changes to file "Light.java" and "Strand.java". PLEASE don't import anything new and keep it simple. The output of the program has to be the same as the sample runs in the rubric.

AP Computer Science Coding Assignment 9-Light/Strand Name Due Date: Sunday March 10 This assignment creates two class fles: one that represents a single colored ight bulb and the second that represents a strand of colored lights (think of lights people use to decorate First write class ca led Light that represents a single ght bulb. Make sure that your variables are PRIVATE and your methods PUBLIC. Make sure ALL METHOD NAMES MATCH the names below so they will work with the runner program. Also make BOTH files are commented at the top with the standard name, period& disclaimer AND that you comment the body of your code. Then write a class called Strand that represents a strand of lights. The Strand dass needs the Light dass to work properly. Test both files using LightStrandTester.java from Blackboard. Grading considerations, out of 50 points: Code is commented for every method in BOTH files: 10 points (S points each constructors in Light S points toString in Light: S points other methods in Light: 10 points 2 constructors in Strand: 5 points toString in Strand: S points other methods in Strand: 10 points Light ava Variables: boolean on- Represents whether the light bulb is on or off. Set to true if the light bub is on, false if off .boolean buntOut Represents whether the light is burnt out or working properly. Set to true if the light bulb is burnt out, false if it is working. String color-Represents the color of the light bulb with possible values of 'red, "blue", "green" and white.No other color values are allowed Methods LightD-Default constructor that sets the bulb to on, not burnt out, and "white Light boolean a, boolean b, String c)- This constructor sets the on variable to the parameter o. The burntOut variable is set to the parameter b. If buntOut is true, on is set to false, no matter what value is stored in o. The color variable is set to conly if c is "red, "green or "blue". The constructor ignores the case of the value in c, and stores the value as a lower-case String. If c holds any value other than "red green or blue", color will be set to white String toString returns a String with the Light in the format: off red burnt out on green not burnt out Notice there is one space between "off on and the value for color, and a tab before the "burnt out or "not burnt out .vold flip)-This method changes the bulb from on to off, or visa versa. If the burntOut variable is true, then the on variable may only be set to false. String getColor)- This method returns the color of the light bulb. vold setColor String c)-The color variable is set to c only if c is 'red, "green or "blue", ignoning case. The value stored for color should be lower case. If c holds any value ather than "red", "green or blue ignoring casel the method sets the color to "white boolean isOn)-Returns true if on, false otherwise . vold bumOut)-Sets burntOut to true and on to false. .boolean isBurntOuti) Returns true if burntout, false atherwise ArrayList strand-An ArrayList that stores a strand of ights. Strand)-Default constructor that creates the strand to an ArrayList holding one turned on white bulb, that is not burnt out Strandlint n) A constructor that sets creates AnrayList of size n, holding n white bu bs, that are all turned on and not burnt out. If nsO, then the strand should be set to size one, with a white bulb, on and not burnt out. String toString)-This method returns a String representation of the Light objects in the ArrayList, one per ine. For example: on green not burnt out off red not burnt out off green burnt out on blue not burnt out on red not burnt out vold setColor(String c) This method sets the color of al variable is set to c only ifc is "red green" or blue". It should ignore the case of the value in c. Ifc holds any value other than "red", "green" or "blue", color wilbe set to "white the ight bulbs in the entire Strand. The color . . void setMultiD-This method sets the color of a l the light bulbs in the entire Strand to the pattern "red green", "blue, "red","green", "blue", until the end of the Strand. .void turnOnD-This method turns on all the lights in the strand. Each individual bulb can only be turned on if it's buntOut variable is false vold turnoff)-This method turns off all the lights in the strand. .void bumOut int i-This method sets the Light at location i's burntOut variable to true int getsize)-returns the length of strand Sample Run 1 Czeate light ane with default eonatrueto est burnout on light1 2.
