Do not create packages. Use the default package

Complete the class RectangleWork given to you. You will find it at the Codecheck URL below.

You will use the Rectangle class in the Java library. You will need to import java.awt.Rectangle. To look at Rectangle's public interface type java api rectangle into Google or other search engine

Do the following:

Create a rectangle with a width of 100 and a height of 60 at x = 50, y = 150.
Get the x coordinate using one of Rectangle's methods and print it.
Call the translate method to move the rectangle 10 pixels in the x direction and 20 pixels in the y direction.
Print the new x and y in this format: x, y (Rectangle has methods to get x and y)
Call the grow method of the Rectangle to make the rectangle 50 units wider leaving the height unchanged. Be sure to read what the grow method does.
Print the new width using one of Rectangle's methods

In this problem you will use various String methods. Complete the class StringsForAll given to you. You will find it at the Codecheck URL below

print 4 times the length of the given word (use a string method - do not just print 20 or 24 or ...). Note: There is a String method length() which returns the length of the String
print the uppercase version of the word (do not change the original word)
replace "s" with "$" Do not change the original word
print the changed word and the original word on the same line separated by a space
replace "r" with "12" in the changed word
replace "a" with "4", in the new changed word
print the string with all the replacements
print the original word.

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 must use the String replace method to replace characters. No credit for simply printing the word with replacements or replacing the entire word.

Note: When you submit your code to Codecheck, it will first run with the given word(rates) but then it will run again with a different word. You do not need to worry about that. It will happen automatically. If your code is correct, the second word will also execute correctly.

Codecheck URL

When UNIX was developed, the date January 1, 1970 was set as time 0 and time was measured from that point in seconds. Itis often calledmthe UNIX epoch. You will use the Day class from Chapter 2 Worked Example 1 to calculate the days from today to that date.

Write a program Timestamp which will calculate how many days in the past the epoch was from today (whatever day the program is run).

You will find the Day class at the Codecheck URL below.

Create a Day object representing today
Print it like this.
```
System.out.println(today);
```
Create an object representing the epoch date
Then print how many days ago the epoch day was. This will be a negative number.
