Step by step
Solved in 3 steps with 1 images
- write a for-each loop that prints all the elements in a collection of Student objects called role. what is required for that loop to work?A for construct is a kind of loop that operates on items included in a list. Because of this, it continues to operate for as long as there are objects to be processed in the system. Is this statement correct or does it include an error?A for construct is a type of loop that works with the things in a list. Because of this, it will keep running as long as there are items in the system to be handled. Does this statement make a mistake or is it correct?
- What criteria should be used to evaluate an ArrayList's performance?Unique Words Summary Specifications:You are tasked to implement an abstract data type class which takes in a given input file called input.txt, and processes, identifies and sorts all unique word instances found in the file. Sample InputHi hello hi good bye goodbye Bye bye good say Sample OutputBye Hi bye hello hi say The input.txt file is found along with the zip folder where this instructions file also came along with. Note: you are not allowed to use pythonic lists, and its methods and functions, and string methods. However the use of the file handling methods (read readlines and readline) are allowed for this project.How can you evaluate the state of an ArrayList to assess how effectively it is functioning?
- A map interface's list collection viewsWrite 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. 1 #include HNm in 10 m DO G 2 3 int main(void) { 4 5 6 const int NUM_VALS = 4; int courseGrades [NUM_VALS]; int i; 7 8 for (i = 0; i < NUM_VALS; ++i) { scanf("%d", &(courseGrades[i])); 9 } 10 11 12 13 14 15 } /*Your solution…Write a for loop to print all elements in courseGrades, following each element with a space (including the last).

- write a while loop that uses an explicit iterator that prints all the elements in a collection of Student objects called role.Use the right loop for the right assignment, using all the follow- ing loops: for, while without hasNext(), while with hasNext() and do-while. So I cannot use array. it has to be done in java.In this java assignment, we will need to use arraylists so we can store data for an employee. If the user wants to enter data for more than one employee, it should print like this: Employee ListId Name ----------------------- 1. First Name 2. Bob Smith If the user only enters one employee, it should print out a paystub for that employee that would look like this (with overtime coming into play as well, paying an extra 50% beyond 40 hours): ------------------------------- Id - 1 Name - First M. Last Address - 1234 Main St, City, St, Zip Phone - 1234567890 Email - sample@gmail.com Hours worked - 45 Hourly Rate - $10 Regular Pay, 40 hours at $10/hr - $400 Overtime Pay, 5 hours at $15/hr - $75 Gross Total - $475 ------------------------------ Federal tax (20%) - $95 State Tax (5%) - $23.75 Fica Tax (3%) - $14.25 ------------------------------ Net Check - $342 The program should have one class per .java file all calling to a main.java file using getters and setters.
