A bit new to methods and need a little bit of help. Swap Method Your task is to write a public static method named swap that takes a single parameter which is an array of doubles. This method should swap the first and last element in the array and then return the adjusted double array. You can assume that all arrays passed into the method are a length of 2 or more. For example, the test data provided when passed into the swap method should go from: {8.34, 7.221, 10.643, 93.2} to
2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates 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] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right 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] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Write method body of following methods: InsertNum(int num) // The function takes a number from user as input and it is intelligent enough to place the number at desired index of an array. For example if array has values from 1,3,5,7 and user entered 6 so the function will place 6 after 5 and before 7. (Use While Loop) InsertNum(int num,int position) // This function takes number and position from user and then place the number at desired position of array. Remember to ask from user if there is already a number at that position. (Code in C++)
Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples

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 ]
Fibonacci series, the numbers obtained by adding each number with the number before it. a)Define a method that takes the index value as a parameter and calculates the value for the corresponding index of the fibonacci series. example=: fib(3) = 2 , fib(6) = 8 b) Define a second method that takes an integer value as a parameter. In this method, create an array with the size of the value taken as a parameter, and save the corresponding values in the fibonacci series to each element of this array using the first method you created. exapmle=photo

Java: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting. Paste your code into the placeholder at the top of the file. I strongly recommend running this program before you submit your homework. The program is designed to help you catch common errors and fix them before submitting.…

JAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. 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…
Shift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right 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] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]
