- Functions with 2D Arrays in Java Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7. First line contains the size of the array 8.

The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method. Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2 Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average. If the number of elements in an array is odd don't modify the last number of the array. Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…

The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument.

Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]

In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by “O”) at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection (“Left”, “Right”, “Up”, or “Down”). Based on these directions, you will try tomove the player.• If the location is valid (represented by “_”), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by “X”), you will tell the…
- Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. Output all elements of userCounts in reverse order, following each element with a space, including the last. After the final output, end with a newline. Ex: If the input is 4 54 56 75 7 then the output is: Array contents in reverse: 7 75 56 54 Note: The loop should start with i = userCounts.length - 1 and end with i = 0. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserLog { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; inti; numVals=scnr.nextInt(); int[] userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } System.out.print("Array contents in reverse: "); /* Your code goes here */ } }TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).
