in java eclipse. Please add comments in each step. I have stared the code please in the same code add the following question. Thank you I have done this part(this is only for reference): Part 1: a. Create a 1D array of integers to store 50 integers. b.Store values from 0 to 49 into the array you just created. c.Create a new String Object using no-arg constructor. d.Using for loop append the array elements one by one to the String (one per loop iteration) e.Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). E.g. “It took ______ nanoseconds to append 50 integers to the String This part is what I want please. 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.)) E.g. “It took ______ nanoseconds to append 50 integers to the StringBuilder 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 The image is the code started. I'll appreciate your help. I have asked the same questions multiple times.

I have done this part(this is only for reference):
Part 1:
a. Create a 1D array of integers to store 50 integers.
b.Store values from 0 to 49 into the array you just created.
c.Create a new String Object using no-arg constructor.
d.Using for loop append the array elements one by one to the String (one per loop iteration)
e.Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)).
E.g. “It took ______ nanoseconds to append 50 integers to the String
This part is what I want please.
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.))
E.g. “It took ______ nanoseconds to append 50 integers to the StringBuilder
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 |
