- Type up the code, execute and submit the results ONLY. 1. Enter a valid array index2. Enter an invalid array index3. Enter a letter instead of an integer – NOTE: Using the general error will show you the type of exception was caught, and you can then update your code to catch that type of error.4. Try putting the “Exception e” before the IndexOutOfBoundsException eob what happens and are you able to run the code – what happens?1) Demonstrate that when a ten element array, a, is passed, if the the called method can change the value of each element, and those changes will also change the array elements in main(); the called method must not have a return statement Before passing the array, have main() display it, and write it to a file named beforechangeAfter the change, display it and write its contents to a file named afterchange After the called method completes, main() displays the contenets of both files, beforechange afterchange Before populating array, a, from the keyboard, verify the entry is what the program expects Note:- Please type and execute this java program as soon as possible and also need an output for this java program.write a function called fillArrayFromFilethat will read numbers from a file that contains one double per line into an array(up to the size of the array) and then returns the number of doubles successfully readfrom the file. You may assume that the file contains valid doubles
- Computer Science Write a program that uses 3 command line arguments to search a list of float numbers in a file and prints out the result of whether the number was found or not on the console. Also, it prints the array in the reverse order (not sorted but reverse order of how the numbers were read in). The first argument is the name of the input file which has the numbers to be searched, the second is an integer specifying how many numbers are in the input file and the third argument is the float number being searched for. Use dynamic memory allocation for the array and use a function (that returns a boolean value) to do the searching. Also make sure in the beginning of your program, that the program will execute only if exactly three arguments (other than executable name itself) are specified. at the command line.Write a Java code that creates two files with the names file4 and file4a. create two int arrays with 10 elements each with the names arrfile4 and arrfile4a; these arrays are to have different values write the contents of arrfile4 to file4write the contents of arrfile4a to file4aWrite a program that takes an integer array and perform following operations sum, average, percentage,. The user must non zero integers. If they were not an integer, the program would throw a NumberFormatException if user try to input string instead of integer value. If denominator were Zero, the program would throw an ArithmeticException and Display the exception.

The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.
