What type of object is created by the OpenText method? a. File b. SequenceReader c. StreamWriter d. None of the above.
If you call the File.CreateText method and the specified file already exists, what happens to the existing file?
create an image file programmatically. Your image file should be called OnTheFlyPy.ppm and the code you write to create should be in a public static void makePPM() method defined in the provided Main.java class.
Your OnTheFlyPy.ppm should be be 100 pixels wide and 100 pixels tall and the PPM header lines should be correct.
The first two rows and last two rows in the OnTheFlyPy.ppm should be red (Red=255, Green=0, Blue= 0).
The first two columns and last two columns in the OnTheFlyPy.ppm (except for the part that overlaps with the red pixels you created in the previous part) should should be blue (Red=0, Green=0, Blue= 255).
The remaining pixels in your OnTheFlyPy.ppm image should be white (Red=255, Green=255, Blue= 255). Here is a picture of what your final image should look like:
import java.io.*;
public class Main{ public static void main(String[] args) { makePPM(); } public static void makePPM() {
} }

Disguise the selected word, and display it 4. Ask the user whether to continue, i.e., whether to repeat steps 2, 3, and 4, or quit the application Once the user chooses to stop the application: 5. Display the total number of vowels hidden 6. Display the total number of consonants hidden 7. Display termination message The user will be asked whether to continue playing and will indicate that another game is to be played by answering ‘y’ or ‘Y’ in response to the question, “Want to play again?” asked by the program after displaying each chosen word and its disguised version. If the user’s response is any character other than ‘y’ or ‘Y’, the totals are displayed and then the application termination message is displayed. See examples below.
