Complete the class StringMethods using String methods. Remember that all the String methods are accessors. They do not change the original String. If you want to apply multiple methods to a String, you will need to save the return value in a variable.

Complete the class by doing the following

• print the word in lowercase
• Print the original word
• in the original word, replace 
  "e" with "3" ( Use the unmodified variable word)
• print the new word
• In the new word, replace
  "t" with "7"
• print the new word
• In this new word, replace
  "L" with "1" (uppercase L with the number 1),
• print the final word (with all the replacements)
• print the length of the final word
• the code to print the original word is already included for you. Do not change that statement
  
  You will need to use the replace() method multiple times. Then print the final string. Remember that replace is an accessor method. It returns the changed version of the string. If you want to do something with the returned string - like use replace on it again - you need to save the return value in a variable.

You are given a word in the starter file and Codecheck will test with that word and with a different set of letters

I made a mistake when doing the draft for this problem so I am changing the directions to match what is expected. See below. (Feb 9, 2016)

For the draft, print the word in lowercase and then print the original word. Leave the code where I print the original word.

This problem originally asked for Cinco de Mayo. I made a mistake in my solution. When you create the second object, use May 1 and then it will pass Codecheck. My apologies for having to create Uno de Mayo rather than Cinco de Mayo. (Changed Feb 2, 2016)

In this problem you will complete an application to calculate how many days are left until May Day on May 1, 2016. Use the Day class presented in the Udacity. It is in Codecheck as well

Here is the set up.

• Create a new Bluej project in the cs46a/homeworks/hw02/draft folder. You can call it hw2b_cinco_draft
• Make a class Day in the project and copy in the Day code from Codecheck. You will not modify this class at all.
• Make a class DaysLeftPrinter in the project and copy in the code from Codecheck. This is where you will add your code.

Now you are ready to do the assignment. In the main method:

• Create a Day object representing the current day and assign it to a variable, today . You do that by using the  new Day() constructor with nothing in the parentheses. (See the Day API). That will create a Day object with today's date. You will get a different object if you run the program again tomorrow.
• Create a Day object representing  May Day. This object will be the same every time you run the program.
• Print the second Day using this statement
  
  System.out.println(cincoDeMayo.toString());
  
  
• Calculate the number of days that Cinco de Mayo is from today. You can use methods of the Day class to do this
• Print the number of days
• Don't change the print statement that is already at the end of the class

For the draft: Create a Day object representing the current day and assign it to a variable named today. (Don't change the print statement)

When you are ready to work on the final, copy the Bluej project hw2b_cinco_draft into the cs46a/homeworks/hw02/final folder. Change the word draft to final. Open the project hw2b_cinco_final in Bluej and complete the assignment.

Draw the word COAT using the Line and Ellipse class from the Udacity graphics package. Download and unzip the graphics packages if you have not done so. The URL is in the syllabus area of Canvas.

Create a new Bluej project. Select Project->Import ... Navigate to the graphics files and add to your project. Be sure the folder you import contains the files directly and does not contain an extra folder. Your workbench should look like this.

Create a class called CoatViewer in the project. Add a main method to the class. There is no starter file this time

Your drawing should follow these specifications. The code goes in the main method.

• Each letter is 30 pixels wide and 40 pixels height
• There is a 5 pixel gap between letters
• The upper left hand corner of the C is at (20,10). This means the top left hand corner of each letter will have a y coordinate of 10.
• Draw the C in red. Use the pre-defined constant in the Color class.
• Fill the ellipse for the O (Do not draw it). Use a custom color where red is 240, green is 248, and blue is 255.
• Draw the A in magenta. The legs of the A are vertical and connected at the top. The crosspiece is parallel to the top and connects the middle of the legs. Use the pre-defined constant in the Color class.
• Draw the T in green. The vertical line starts at in the middle of the top of the T. Use the pre-defined constant in the Color class.

It is a good idea to figure out the coordinates of each letter before starting to draw. Trial and error is not efficient here.

For the draft, draw the C and the O. (You will fill the O in the final version)
