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]...

Starting Out with Java: From Control Structures through Objects (7th Edition) (What's New in Computer Science)
- An array is a single statement that declares a variable and provides array values as its content. Choose one: a.literal b.builder d.index C.elementarrow_forwarddo the following: - Create an array of the following temperature readings: 36, 5, 10, 24, 40, 31 - use a loop to find the sum of the elements in the array. -find the average of the numbers. if the average is more than 30 display the message "TOO HOT" on screen otherwise check if the average is between 15 and 30 display the message "MODERATE" otherwise display the message "TOO COLD".arrow_forward5. 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_forward
- A single statement that declares a variable and specifies array values as its content is called an array Select one: a.literal b.constructor C.element d.indexarrow_forwardIn order to access each element in an array, the Do...Loop statement needs to know the highest subscript in the array. True or False?arrow_forward2. Creates an array of Triangle type of size 10. Prompts the user to enter the index of the array, then displays the area of corresponding element value. If the specified index is out of bounds, display the message Out of Bounds.arrow_forward
- Declare a variable named num with an initial value of 0. Create a while loop that will print "Keep going" as long as the value of num is less than 5. Use window.alert() for displaying the output. Create a function named showProd that returns the product of n1 and n2. Using the new keyword, create an array named info with three (3) values: your first name, your nickname, and your last name.arrow_forwardIn visual basic Write a For…Next loop that will printout each value in the array from problem 4.arrow_forwardHomework - identical arrays for one-dimensional: Write a test program which prompts a user to enter the size of two arrays as well as to fill their elements. After that, the program checks the same contents of the elements of the two arrays. If these arrays are equal, the program displays message which is "The two arrays are identical". If not equal, displaying "The two arrays are not identical". Write an equals method that reads two arrays and displays these messages above.arrow_forward
- Declare 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. O a. Associative O b. Positive O c. Numeric O d. Nonearrow_forwarda. 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 Stringarrow_forward
