a. Declaring string array:
The statement which is used to declare “String” array with the values “Mercury”, “Venus&...
Explanation of Solution
b. Loop to display each element in the array:
//Class definition
public class Sample {
// define main function
public static void main(String[] args) {
// Declaration of string array
String[] scientists = {"Einstein", "Newton", "Copernicus", "Kepler"};
// Loop to read each element in scientists array
for(int i = 0; i<scientists.length; i++)
// Display contents of the scientists array
System...
Explanation of Solution
c. Loop to display total length of the all strings present in the array:
//Class definition
public class Sample {
// define main function
public static void main(String[] args) {
// Declaration of string array
String[] scientists = {"Einstein", "Newton", "Copernicus", "Kepler"};
// Declare and initialize the variable
int total = 0;
// Loop to read each element in scientists array
for(int i = 0; i<scientists.length; i++)
/* Using the length() method read the length of strings present in the array */
total += scientists[i]...

- 5. Create an array that contents 10 integer elements, and let user randomly input 10 values and put into the array, Sorts array elements in ascending order, and then print out the array element.arrow_forwardDeclare an integer and an array of doubles called pointValues The array can hold 110 doubles Ask the user how many points they want to enter (up to 110) Get the number from the user Fill the array with with user input (HINT: use a loop and prompt for input) For example if the user entered 100 you would write a loop to have the user enter the 100 pointValues one by onearrow_forwardArrays where the index is a string value.

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.)).

Make sure that you preallocate the vector!arrow_forward
- Grade Book A teacher would like to assign a letter grade to a student, based on student's test score. Write a program to help this teacher managing her students' test score. Use the following grading scale to assign a letter grade to a student. Test Score Letter Grade 80 - 100 A 70 - 79 B 60 69 C 50 - 59 0- 49 F Your program must have an array of string objects to hold the student names and an array of int to hold the student scores. Let the teacher determines the number of students and ask the teacher to enter the information for each student. Your program should have the following programmer-defined functions: getInput () - to read the students name and scores from user getGrade () - to determine the letter grade corresponding to the score getReport () - to determine the maximum, minimum, average and standard deviation of the scores Display an error message if the teacher enter mark below 0 or above 100, and keep asking for a valid value. The program should also be capable of…arrow_forwardQuestion 1 Write a program that declares an array of 100 doubles. The program asks the user to enter a number N between 100, and then: initializes the first N elements of the array to random numbers between 1 and 100. calculates the average of these numbers and displays it. A final loop displays the elements of the array, each on a line, with an indication as to whether that number is lower or higher than the average. For example, if the numbers generated are 5, 28, 3, 8, 15, 7, 22, 6, 1, 4, then the program will print: Average = 9.9 5 28 3 8 15 7 22 6 1 4 11 11 11 -- 11 11 1- —— 11 lower than average higher than average lower than average lower than average higher than average lower than average higher than average lower than average lower than average lower than averagearrow_forwardWrite the JavaScript Code to achieve the following: Declare three variables—one number and two strings. The number should be 120 and the strings should be “5150” and “Two Hundred Thirty”. Create a new array with three numbers and two strings or words. Use the alert () function to display the following string, properly escaped: Steve’s response was “Cool!”. Create a loop statement.arrow_forward
