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...
Homework Assignment on Mimir: Read in a file "numbers.txt" into a Java program. Sum up all the even numbers over 50. Print the result to the console using System.out.println(); The file will only have numbers. Code: import java.io.FileNotFoundException; import java.io.FileReader; import java.util.Scanner; /** * * @author David */ public class ReadingFiles { /** * @param args the command line arguments */ public static void main(String[] args) throws FileNotFoundException { // TODO code application logic here...
You will write a single java program called MadLibs. java. This file will hold and allow access to the values needed to handle the details for a "MadLibs" game. This class will not contain a maino method. It will not ask the user for any input, nor will it display (via System.out.print/In()) information to the user. The job of this class is to manage information, not to interact with the user.I am providing a MadLibsDriver.java e^{*} program that you can...
Write a program that will check a Java file for syntax errors. The program will ask for an input-file name and output-file name and will then copy all the code from the Java input file to the Java output file, but with the following changes: 1. Any syntax error found in the Java input file will be corrected: a. Missing semicolon b. Missing compound statements (curly braces) c. All comments have to start with // and end with a period....
1) Consider the following Java program: 1 public class HelloWorld { 2 // My first program! 3 public static void main(String[] args) { 4 System.out.println("Hello, World!"); 5 } 6 } What is on line 1? a. a variable declaration b. a statement c. a method (subroutine) definition d. a comment e. a class definition 2) Which one of the following does NOT describe an array? a. It can be used in a for-each loop. b. It has a numbered sequence...

4.3Learning Objective: To read and write text files. Instructions: This is complete program with one Java source code file named H01_43.java (your main class is named H01_43). Problem: Write a program that prompts the user for the name of a Java source code file (you may assume the file contains Java source code and has a .java filename extension; we will not test your program on non-Java source code files). The program shall read the source code file and output...
# Java import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.stage.Stage; public class Test extends Application { @Override // Override the start method in the Application class public void start(Stage primaryStage) { // Create a button and place it in the scene Button btOK = new Button("OK"); btOK.setOnAction(e -> System.out.println("OK 1")); btOK.setOnAction(e -> System.out.println("OK 2")); Scene scene = new Scene(btOK, 200, 250); primaryStage.setTitle("MyJavaFX"); // Set the stage title primaryStage.setScene(scene); // Place the scene in the stage primaryStage.show(); // Display the stage...
the answer must be in java. thank you Question 2 [8 points] Consider the class Class A below: class Class A implements Serializable{ int a; static int b; transient int c; String s; // Constructor public Class A (int a, int b, int c, Strings){ this.a = a; this.b = b; this.c = c; this.s = s; Complete the class Test to test the serialization and deserialization of the objects of class Class A. State the possible variable values following...
Complete the following Java program by writing the missing methods. public class 02 { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("Enter a number: int n = scan.nextInt(); if (isOdd (n)) { //Print n to 1 System.out.println("Print all numbers from "+n+" to 1"); printNumToOne (n); } else { System.out.println(n + " is //End of main()
