3. Write 5-6 lines of code to open a PrintWriter and write out the contents of the plants array into a text file named plants.txt

(Flattening arrays with flatten vs. ravel) Create a 2-by-3 array containing the first six powers of 2 beginning with 2^0. Flatten the array first with method flatten, then with ravel. In each case, display the result then display the original array to show that it was unmodified. Please use Python and keep it simple.

(Intro to Java) Open a new Java file called ArrayMethods.java. Read the Javadoc comment for each method below and write the method according to the description in the comment Once you are getting the correct output for all tests inside of main, upload your source file to Canvas public class ArrayMethods {    /**     * Displays the contents of an array on the console     * with each element separated by a blank space     * Prints a new line character last     * @param nums the array to print to the console     */    public static void printArray(int[] nums) {        return;    }        /**    * Assuming an array of integers, return true if 1    * is the first element or 1 is the last element    * Note: you may assume that you will be given an array    * of at least length 1    * is1FirstLast([1, 2, 10]) → true    * is1FirstLast([10, 1, 2, 1]) → true    * is1FirstLast([13, 10, 1, 2, 3]) → false    * @param numbers the array of int numbers    * @return whether or not 1 is the first or…

(in java) (with a screenshot of the code please) write a java program that contains 2 arrays, one for 10 students names and the other for their grades  they must be all entered by the user -the names array will be a 1d array (single array) -the grades array will be a 2d array and it will have 3 rows and 10 columns, the first one is will represent the first exam, the second will represent the second exam, and the third one will represent the final exam finally, you will do a loop that will calculate the sum of all exams for each student
