Note: Please answer the question in Java only: The Problems - contains only problems from the last 2 contests Separate Un-Attempted, Attempted and All cards Problem Difficulty Rating - The Featured drop-down menu has different difficulty ranges so you can try problems that best suit your experience. Popular topics and brands Like most users, Chef didn't know that he could add problems to his personal to-do list by clicking the magic "+" symbol in the upper right corner of each problem page. But once he found out about it, he went crazy and added a lot of problems to his to-do list without looking at their difficulty rating. Rajesh is a beginner and ideally should only try to solve problems strictly below 10001000. Given the difficulty rating list of problems in Chef's to-do list, please help him determine how many of these problems Chef should remove from his to-do list so he is left with only problems with a difficulty rating of less than 10001000. Input 1 4 999 1000 1001 1002 Output…

Small Program assignment based on basic java features (Class, Object, Constructor, Method, Output, If-else, Loop, Array Etc)    Note: USe all the topic what mention in above and dont copy from bertlyby .i post this question 3rd time so please give me correct answer

New java code can only be entered lines 4 - 10.

basic java code, self-learner here so pls do use more // comments ya if needed pls label the solution with the question label

Problem: Bugs are simple creatures that only know how to walk towards other bugs. Bugs maintain information about their (x, y) position; by which it can tell if they are standing next to other bugs. Watch the following video: bug movement. Create a java project that simulate bugs movement. You need to write a class “Bug" that models a bug moving along a straight line and it can turn to change its direction counterclockwise (i.e. 90 degree to the left; north → west → south → east → north). In each move, its position changes by one unit in the current direction. Details of the "Bug" class is described below. Your simulator should read information of an unknown number of “Bug" objects from an input file called “Bugs.txt". Each line represents a bug and the initial position and facing direction of this particular bug. Keeping the first bug position as a reference the simulator should move the second bug next to the first bug forming a cluster and its final position and direction should be…

Java Question - For some reason, my code seems to always output an error in the Java Compiler. I am not sure what's the mistake. If you could fix the problem, I would appreciate it. The code and error message is in the pictures. Thank you.

Cannot compile on java the problem is chapter 5, PC #10 page 346 in starting out with java early objects version 6 by Tony Gaddis. I believe that there is a bracket missing in the text on your site as I keep getting a parsing error at the final line of the code on the "Test" program.  I have tried to place it where I thought it should belong but that just caused more errors.  I will attach the code to this request

ompiling and Executing a Java Program Summary In this lab, you compile and execute a prewritten Java program. Instructions Execute the program. There should be no syntax errors. Modify the program so it displays "I'm learning how to program in Java.". Execute the program. Modify the Programming class so it prints two lines of output. Change the class name to Awesome. In Java, the file name must match the class name, so change the file name to Awesome.java. Add a second output statement that displays "That's awesome!". Execute the program.

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…

Grey lines (start-13 & 17-end of code) can NOT be changed.  New JAVA code must go inbetween code

Instructions The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. An example of the program is shown below: Enter name Juan Hello, Juan!   Task 1: The DebugThree3 class compiles without error.   Task 2: The getName() method accepts user input for a name and returns the name value as a String.   Task 3: The displayGreeting() method displays a personalized greeting.   Task 4: The DebugThree3 program accepts user input and displays the correct output.

Part 4:  Methods The following is Java pseudocode.  For this exercise, you can assume the input function provides an appropriate integer value.  Line numbers are provided on the left.  System.out.print will print the information to the same line.  System.out.println will print the information and then go to the next line.  // is a comment.  Do not worry about public static.  Code execution starts with the main method.    For each method used, make sure to provide a separate table showing what the values are and how they change (i.e. tracing through the code).  All variables passed in have values.  Don’t worry about showing how the input() method works.     7    public static int test1(int x1, int x2){  8           9         if(x1==0){ 10            x1=10; 11         } 12         if(x2==0){ 13            x2=10 14         } 15          16         return x1*x2; 17    } 18     19    public static int test2(int x2, int x1){ 20         return x2-x1; 21    } 22    public static int input(){…

new java code can only be added after line 17.

Do not attempt, if you are using other's work. I'll give multiple dislikes for plagiarism and also will report your account. Give unique answer others are wrong. Question: Write a Java program that takes user input for two numbers, multiplies them, and prints the result. Ensure that your program is user-friendly, handling different data types, and providing meaningful output. Submission Guidelines: Use appropriate variable types for user input and the result. Implement input validation to handle unexpected user inputs. Print a clear and informative message along with the result.

I need help with this question in my intro to Java class. I have included what I have so far but I am not getting what I should be and dont know what I am doing wrong.

OverviewIn this task, you should write a program that asks the user to enter one or more sentences. The program counts and prints on the screen how many sentences, words and characters the user wrote. TaskWrite a java program that prompts the user to write a text with one or more sentences. The program will then print on the screen how many sentences, words and characters the user entered. You can assume that:•    one sentence:always ends with a period (.), an exclamation point (!), a question mark (?) or the user presses 'enter' on the keyboard.• words:always separated by a space () or the user presses 'enter' on the keyboard.•    a sign:is any character in the text (string) that the user enters.Tip• StringTokenizer, String.split and / or Scanner.

JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
