1- Arrays can be created to store values of multiple data types at one place.     True     False 2- To copy the contents of one array to another you must copy the individual array elements.     True     False

Java

True or False: Whereas in many languages the elements stored in arrays must all be of the same type, elements in Javascript arrays can all be of different types, including null and undefined.   a. false b. true

The intNum array is declared as follows: Dim intNum(,) As Integer = {{6, 12, 9, 5, 2}, {35, 60, 17, 8, 10}}. The intNum(1, 4) = intNum(1, 2) - 5 statement will _____________________. a. replace the 10 amount with 12 b. replace the 5 amount with 7 c. replace the 2 amount with 4 d. None of the above.

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…

The Java language definition demands that all references to array elements be checked to ensure that the index or indices are in their legal ranges, is an example of VS ____. (one word answers) Blank # 1 Blank # 2 A A/

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.  Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations.   Remember to validate the input and display an error message if the user inputs invalid data.  Documentation and the screenshot(s) of the results.  Example:  1  2  3 4  5  6 7  8  9 the result will be :  1  4  7 2  5  8 3  6  9

Write the pseudocode statement that will make a variable testAverage equal to the average of the first 3 scores in an array testScores.

Can you write it in Java, add comments    Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value.
