1. What is the output of the following program? import java.util.Scanner; public class Factorial { public static void main(String args]){ Scanner scanner = new Scanner(System.in); System.out.printIn("Enter the number:"); int num = scanner.nextInt(); int factorial = fact(num); System.out.printIn("Factorial of entered number is: "+factorial); } static int fact(int n) { int output; if(n==1){ return 1; } output = fact(n-1)* n;

Please create a flowchart for the following program: // Import Scanner classimport java.util.Scanner; // Create a class Trianglepublic class Main{ // Method used to check given three sides form a valid triangle or not public static boolean isTriangle(double a, double b, double c) { // If sum of any two sides is greater than third side if((a+b > c) && (a+c > b) && (b+c > a)) { // Print triangle is valid System.out.println("Three sides form a valid triangle."); // Return true return true; } // If any of the above condition is false else {// Print triangle is invalidSystem.out.println("Three sides form a invalid triangle.\n"); // Return false return false; } } // Method used to compute the area of triangle public static double triArea(double a, double b, double c) { // Compute s double s = (a + b + c) / 2; // Compute the area of triangle double area = Math.sqrt(s*(s - a)*(s - b)*(s - c)); // Return the...

Hi, I am struggling a bit with this problem. (This is in Java by the way.) Provided code: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userText; // Add more variables as needed userText = scnr.nextLine(); // Gets entire line, including spaces. /* Type your code here. */ }}

JAVA CODE: check output

Edit the code below to print the volume of the room

Examine this code and determine what happens when it is run: 1 public class Test { int x; 2 3 public Test(String t){ System.out.println("Test"); } public static void main(String[] args) { Test test = new Test ("boo"); System.out.println(test.x); } 4 5 6 7 8 10 } The program has a compile error because Test does not have a default constructor. The program has a compile error because System.out.println method cannot be invoked from the constructor. ) The program runs successfully and prints out: Test O The program has a compile error because you cannot create an object from the class that defines the object.
