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]

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 ]
1. Code a method that will read in values from the user. 2. Add the following:  Allow the user to enter any number of positive integers  Store them in an array or array list  Let the user enter -1 to end their list of values.  Add error checking to make sure they enter positive values or a -1.
In main: Declare an array capable of holding five Strings. Populate the array by entering five first names all on one one line separated by spaces (see sample output but use different names). Use a foreach loop (see page 255) to process the array and display the names on one line separated by spaces. Pass the array to a void method. In the void method: Sort the array. Create an arraylist of Strings. Use a loop to populate the arraylist with the Strings in the array that was passed it. Insert another name (you choose it) at the start of the arraylist. Remove the name at the end of the arraylist. Use a foreach loop to process the arraylist and display the names on one one line separated by spaces.
TASK 1 Write a Java method that returns the index of the smallest element in an array of integers. If the number of such elements is greater than 1, return the smallest index. Use the following header: public static int indexofLargestlestelement(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the index of the smallest element, and displays the index.
3. write a method called insert that inserts an element into an integer array. It should take 3 parameters: an int array, the number to be inserted and the index it should be inserted at. It should return a new array that has the element inserted at the index (the new array should have a length 1 longer than the original array).
a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b. Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4] b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array. class Main {public static int[] createArray(int a, int b) {}public static void main(String[] args) {}}
Q1: Write a program to accomplish the following tasks:- a) Write a method to print the ArrayList in the reverse order b) Write a method to sort the ArrayList, and display the data after sorting c) Write a method to print the largest and the smallest element in the ArrayList d) In the main method ask user to enter 10 integers, store them in the ArrayList, pass the ArrayList to above methods, and then display the result
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).
Create a class containing the main method. In the main method, create an integer array and initialize it with the numbers: 1,3,5,7,9,11,13,15,17,19 Pass the array as an argument to a method. Use a loop to add 1 to each element of the array and return the array to the main method. In the main method, use a loop to add the array elements and display the result. Note: In the loops, use the array field that holds the length of the array and do not use a number for array length.
