I need to write a program called Deleted_position.java that has a method with one int array as a parameter, and an integer position, where 0

Write a class method named countOccurences that returns the number of times a particular integer occurs in an array of integers. The integer and the array will both be parameters.

Based on the information in the screenshots, please answer the following question below. The language used is Java and please provide the code for it with the explanation. Create a testing class named “PlanTest”. Under this class, there needs to be another static method besides the main method: You will need to create a static method named “prerequisiteGenerator” under “PlanTest”, which return a random 2D array containing prerequisite pairs (e.g., {{1, 3}, {2, 3}, {4, 2}}). The value range of a random integer is [0, 10] (inclusive). This method will accept an integer parameter, which specifies the length of the returned array: int[][] pre = prerequisiteGenerator(3); // possibly {{1, 3}, {2, 3}, {4, 2}} Under the main method, you will need to use prerequisiteGenerator to generate random prerequisite pair lists, and perform tests on plan method at least three examples by printing proper messages. Given 4 courses and prerequisites as [[1,0], [2,0], [3,1]] It is possible to take all…

Write a program called Range_array.java that has a method with one integer array and two integers position1 and position2 as parameters, where 0<=position1<=position2<=a.length-1. The method should construct and return an array that is identical to the given array, but with the values in position1 through position2 deleted. The output should look exactly like what is pictured below please. The code must be editable, and all variables defined within please.

Write a program called Deleted_position.java that has a method with one int array as a parameter, and an integer position, where 0<=position<=a.length-1. The method should construct and return an array that is identical to the given array, but with the value in position deleted (Note that the resulting array should have length 1 less than the given array).  The output should look like exactly what is pictured below please.

Could i get help with this java program where you have to write a static method which reverses an integer array. The array will be a parameter to the method. Put the method in a Test class Your method would be called as follows int [] num = {2, 3, 5, 7, 11, 13, 17}; // Call the method to reverse the array Test.reverse(num); Your method should not print anything. It will be called by the following program: import java.util.Scanner; public class Main { public static void main(String [] args) { // Create a scanner object Scanner in = new Scanner(System.in); System.out.print("How many numbers: "); int len = in.nextInt(); int [] num = new int[len]; System.out.print("Enter " + len + " numbers: "); for(int i = 0; i < num.length; i++) num[i] = in.nextInt(); Test.reverse(num); System.out.print("The numbers reversed are:"); for(int i = 0; i < num.length; i++) System.out.print(" " + num[i]); System.out.println(); } } This program will read in the array and use your method to reverse the…

Write a complete Java program named Transpose that contains the following:   The main method asks the user to provide n - the number of rows and m – the number of columns for a rectangular matrix of integers from 2 to 10. The main method calls the matrixSetUp() method which creates a rectangular matrix of specified dimensions and populates it with random integers from 0 to 99. Hint: You can use Math.random() to generate random numbers. The main method prints the matrix created by the matrixSetUp () method in the form of a matrix. Hint: in order to print the array in the example format, you can use Arrays.toString(matrix[row]) to print each row. The main method calls the matrixTranspose() method that creates and returns a transpose of the initial matrix. Hint: matrix transpose means: ����������[���][������]=�[������][���] The main method prints the transpose of the matrix.

Define an empty array with 4 elements inside the "main" method. The value '-1' from the user to this arrayRecord the numbers entered by the user in order until they arrive. User array with 4 elementsAfter adding, write the required method so that it can continue adding elements. This method will take the array as a parameter, expand the size of the array and return the array variable.will return. Using this method you defined, the user can add elements to the array.make it continue.

This question is in javaYou are walking along a hiking trail. On this hiking trail, there is elevation marker at every kilometer. The elevation information is represented in an array of integers. For example, if the elevation array is [100, 50, 20, 30, 50, 40], that means at kilometer 0, the elevation is 100 meters; at kilometer 1, the elevation is 50 meters; at kilometer 2, the elevation is 20 meters; at kilometer 3, the elevation is 30 meters; at kilometer 4, the elevation is 50 meters; at kilometer 5, the elevation is 40 meters. a) Write a method called dangerousDescent that determines whether there is a downhill section in the hiking trail with a slope of more than -0.05. The slope is calculated by the rise in elevation over the run in distance. For example, the last kilometer section has a gradient of -0.01 because the rise in elevation is 40 - 50 = -10 meters. The distance covered in 1000 meters. -10 / 1000 = 0.01. Your method should return true if there exists a dangerous…

Write a java method called switchThem that accepts two integer arrays as parameters and switches the contents of the arrays. Take into account that the arrays may be of different sizes.
