Complete the application RectangleObject. A Rectangle object has been created for you in the starter file.

Do the following:

• Print area of the rectangle. You must use the Rectangle class' methods getWidth and getHeight. Do not use the numbers directly.
• Use the grow method to decrease the width by 20 and to increase the height by 40. (Remember that the grow method adds the both sides and to top and bottom of the Rectangle.) Print the new area. Again, use the getWidth and getHeight methods.
• Move the Rectangle 10 pixels to the the right and 30 pixels down. Get the left-most x value of the rectangle using getX and print it.

Hint: You can decrease the size of the Rectangle by using a negative number as a parameter in the grow method.

Note: Your code will be run twice - once with the values 50, 10 for width and height and once with two different values for width and height. You do not need to worry about that. It will happen automatically. If your code is correct, you will get the correct answers

For the draft, calculate and print the area of the original rectangle. Do not grow or translate

In this problem you will use various String methods. Complete the class StringPlay

• print the length of the given word minus 1. (use a String method. Don't just enter the number)
• print the uppercase version of the word (do not change the original word)
• replace "s" with "$", "a" with "@", and "e" with "3" in the original word. You will need to use the replace method multiple times.(Do not change the original word)
• print the string with 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 on strings of one character. No credit for simply printing the word with the replacements or replacing the entire word.

Note: When you submit your code to Codecheck, it will first run with the given word, 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,

For the draft, just print the length of the string mnus 1. Note: There is a String method length() which returns the length of the String

Finish the application SnowmanDrawing to draw a snowman consisting of 3 circles centered on top of one another with a hat on top. The centers of the circles fall on a vertical line. The drawing will looks like this:

The dotted rectangle is the bounding rectangle of the middle circle. It is not part of your drawing.

Specifications:

• The upper left hand corner of the hat is at 50, 10.
• The hatbox is 20 x 20. Fill it with black
• The line for the hat brim at the bottom of the hat extends 10 pixels further than the hatbox on each side.
• The diameter of the small circle is 20. The upper left hand corner of its bounding rectangle is at (50, 30)
• The diameter of the middle circle is 40 The upper left hand corner of its bounding rectangle is a (40, 50)
• The diameter of the bottom circle is 60. You figure out this one.

For the draft, fill the hatbox and draw the brim.
