These logfiles contain the last 1000events/messages as well as their status codes.The Logfile FormatBy default, the logfiles are all called ‘logfile.txt’. Each logfile is exactly 1000 lineslong.Each entry in the file consists of 4 fields:1. a line number (starting at 0)2. a POSIX timestamp3. a message/event type4. an event descriptionEach field (line number, timestamp etc.) is separated by a space, except for thedescription which ends with a full stop.Log events come in three different types: NOTIFY, WARNING, and ERROR. Task 1: Display Because the logfiles are so big, we would only like to display a certain number oflines at a time. We prompt the user to choose start and end line numbers andprint all the lines from start to end (inclusive).The input constraints are as follows: 0 start end 999You can safely assume that the inputs will fall within that…Write a Java GUI application to capture travel information between two locations.

- Linux commands: In this part of the lab, you will run Linux commands, capture their output in a format that shows the command and its results in an easy way (command-> new line-> output - > new line-> new line-> command, .... etc). In your output file, make sure to print out the name of your user account and todays date. It should look something like this "My Student Account is " , "Todays Date is ". Can someone please help with this ?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() { } }You will create a new console application, using Visual Studio using C#, that you will call carscount. You will create a text file that will have 5 names of cars and then add one extra car by using push method. This file should be called car.txt and it should be placed inside the Debug folder of your carscount application. You will create a simple program to access this carscount file using streams. In a new line, a text that would say “There are X cars in the park” where X will be the number of lines (number of names of cars plus the extra one) you read from the carscount file. Output "There are 6 cars in the park”.
