First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "StringSlicer" (without the quotation marks) that uses methods to: Get a String from the user at the command line Populate an ArrayList of Character data (the wrapper class), with each char in the String represented as a separate Character element in the ArrayList Output each Character to the command line, each on a separate line NOTE: For this assignment and all future assignments that deal with methods, you should be calling the appropriate method to do the task indicated, rather than implementing the task logic in the ma

Need help with this in Java Implement a "To Do" list. Tasks have a priority between 1 and 9, and a description (which you can come up with on your own, say, "wash dishes"). The program is going to prompt the user to enter the tasks by running the method add_priority_description, the program adds a new task and prints the current list with priority 1 tasks on the top, and priority 9 tasks at the bottom. The program will continue to ask the user if they want to add another tasks, and repeat the add_priority_description method, or enters Q to run the quit method to quit the program. Sample output (not limited to) 1. Study for the final 1. Take the final 2. Watch Justice League with friends 3. Play ball 9. Wash Dishes 9. Clean room. There is a possibility of two tasks having the same priority. If so, the last task that was entered gets to be printed first. Use HEAP in your solution. (Java)

Update it to create a class Student that includes four properties: an id (type Integer), a name (type String), a Major (type String) and a Grade (type Double). Use class Student to create objects (using buttonAdd) that will be read from the TextFields then save it into an ArrayList. Perform the following queries on the ArrayList of Student objects and show the results on the listViewStudents (Hint: add buttons as needed): d) Use lambdas and streams to calculate the total average of all Students grades, then show the result. 1.

Execute the following statements over initially empty ArrayList myList one after another (cascade).

in Jave create a method work() with the follow instructions: If the work() method is passed a non-null then it must return a new List that contains some or all of the elements in data. The elements of the new List must be aliases for (not copies of) the objects in the List it is passed. If there are no sign attributes (i.e., the array is null or has 0 elements) then the work() method must return an empty List. If any of the conditions represented by the sign attribute holds for a particular element that that element must be included in the result (i.e., the conditions must be combined using a logical OR). The elements in the returned List must be in the same order they appeared in the original List (though not all elements must be in the result). public List<T> work(List<T> g){

The WalkingBoard class represents a board with a figure standing on position x,y. Each position also has a value associated with it. Initialise the board in two different ways: either make it size×ばつsize or use the given dimensions and initial values. About the second way: The rows may not be uniform: they may have differing numbers of columns in them. Don’t simply take the argument array: create its copy in the field. All values are set to BASE_TILE_SCORE, or to the given value if that’s bigger. Operations. getPosition: returns the values of x and y in an array. getTile: returns the value of the of the board position. Let this condition be checked by the helper method isValidPosition. If it is an invalid position, throw an IllegalArgumentException. getTiles: returns the values of all the board positions. Don’t let the field contents be accessed from the caller: create and return an exact copy of the structure. getXStep and getYStep: helper methods, they indicate how far (-1,...

In python Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one racer has finished the race. Examples: Copy the following if __name__ ==...

Task 2: Write a static method which takes an ArrayList of Strings and an integer and changes the ArrayList destructively to remove all Strings whose length is less than the integer argument. So if the integer argument is 4 and the ArrayList is: tomato cheese chips fruit butter tea buns pie The output tomato cheese chips fruit butter is:
