Question 1[JAVA] Add a method in the Main class named getLines() that takes a filename as a String and returns each line in the file in an array. Have each element of the array be a String. Do not include the newline at the end of each line. Use a BufferedReader object to read the file contents. Note, the contents of input.txt will be different (including the number of lines) for each test case. Example: getLines( "input.txt" ) returns (an...
PLEASE INCLUDE COMMENTS In java Create a Java Program Add the following comments at the beginning of the file: Your name. The name of the class(es) used in the program. The core concept (found below) for this lesson. The date the program was written. Include a recursive method separate from the main method that will add together all of the even numbers between and including 1 and the value the user supplies. For instance, if the user enters 10 then...
Write a Java code to define an interface called FrugalList which contains a method named pushBack. The method pushBack takes an Object type argument and returns a boolean value.
Please do in java as simply as possible with code available for copy and comments Write a program that reads a file (provided as attachment to this assignment) and writes the file to a different file with line numbers inserted at the beginning of each line. Throw an exception if the file does not exist. An error message should result. For example if file input is: This is a test File output should be 1. This is a test I...
Java Code please read comments and add the code to required lines....LINE 1 to LINE 5 ********************************************************************** * Program Summary: This program demonstrates these basic Java concepts: * - Creating an array based on user input * - Accessing and displaying elements of the array * * The program should declare an array to hold 10 integers. * The program should then ask the user for an integer. * The program should populate the array by assigning the user-input integer...
Programming 5_1: Create a Java class named <YourName>5_1 In this class create a main method, but for now leave it empty. Then write a Java method getAverage which takes an array of integers as it’s argument. The method calculate the average of all the elements in the array, and returns that average. The method should work for an array of integers of any length greater than or equal to one. The method signature is shown below: public static double getAverage(...
Intro to Java Programming Write a method named isDivisible that takes two integers, n and m, and that returns true if n is divisible by m, and false otherwise. Include your isDivisible() function as a method in Functions. In the main static method, demonstrate isDivisible() works by testing that it returns both possibilities correctly for a few different pairs of numbers. Include comments before your test code describing what's going on. The definition of divisibility is "One whole number is...
****WRITE A JAVA PROGRAM THAT : Write a method named stretch that accepts an array of integers (that the user inputs) as a parameter and returns a new array twice as large as the original, replacing every integer from the original array with a pair of integers, each half the original. If a number in the original array is odd, then the first number in the new pair should be one higher than the second so that the sum equals...
This is JAVA language Create a .java class called MoreArrayFun.java with only a main method. This program will use the ArrayManager class. The final version of the program is described below, but initially use it to test your ArrayManager class as you write it. Complete the ArrayManager class as specified below: The class will have exactly two instance variables: An array of integers A count of the number of elements currently in the array The class will have...
***Please give the java code for the below and add comments for different areas for a dummy to understand*** This java program will combine the techniques of handling arrays, decision control statements, and loops. Your program should accomplish the following: Build an array that holds characters (size 35) Load the array with random capital letters (use random generator) Your program should present a menu to the user allowing for the following “actions”. To “search” for a target letter of the...
