in java eclipse. Please add comments. I have stared the code please in the same code add the following question. Thank you  f. Create a new StringBuilder Object using no-arg constructor. g. Using for loop append the array elements one by one to the StringBuilder (one per loop iteration) h. Record a run-time it took to append all integers to the StringBuilder (record run-time of 2.g.)) i. Repeat the testing with 500 and 5,000 elements by again creating new integer arrays with 500 and 5000 sizes respectively. j. Record and display the run-time it took to append all integers to the String and StringBuilder respectively. k. Submit the screenshot of results and a small summary in the form of a table below : Time / size 50 500 5,000  String        StringBuilder

Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {   const int NUM_VALS = 4;   int courseGrades[NUM_VALS];   int i;    for (i = 0; i < NUM_VALS; ++i) {      cin >> courseGrades[i];   }    /* Your solution goes…

please add comment in the code. Answer the questions in java eclipse. Thank you

Hello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method.  Max sure the the last sorted and returned value as the same!
