Write a method that finds the largest element in an array of double values using the following header: public static double max(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the maximum value, and displays the maximum value.
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]
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}

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 ]arrow_forwardPseudocode 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 numMultiplesarrow_forward
- 8. Repetition Use Python Language Write a method that takes in an array as a parameter and counts the repetition of each element. That is, if an element has appeared in the array more than once, then its 'repetition' is its number of occurrences. The method returns true if there are at least two elements with the same number of 'repetition'. Otherwise, return false. Input: {4,5,6,6,4,3,6,4} Output: True Explanation: Two numbers repeat in this array: 4 and 6. 4 has a repetition of 3, 6 has a repetition of 3. Since two numbers have the same repetition output is True. Input: {3,4,6,3,4,7,4,6,8,6,6} Output: False Explanation: Three numbers repeat in this array:3,4 and 6 .3 has a repetition of 2, 4 has a repetition of 3, 6 has a repetition of 4. Since no two numbers have the same repetition output is False.arrow_forwardRotate Right k cells (use python) Consider an array named source.

- Part III Write a method takes one 2-dimensional int array parameter and returns one random column in given array.arrow_forwardMethod Details: public static void rotate(int[] array, boolean leftRotation, int positions) Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help.
