Write a program that removes all non alpha characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld 512334.3517088.qx3zqy7 LAB ACTIVITY 4.17.1: LAB: Remove all non alpha characters 1 import java.util.Scanner; 2 3 public class LabProgram { 4 5 6 public static void main(String[] args) { /* Type your code here. */ LabProgram.ja

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:"); scanner.nextInt(); int factorial = fact(num); System.out.println("Factorial of int num = entered number is: "+factorial); } static int fact(int n) { int output; if(n==1){ return 1; } output = fact(n-1)* n; return output; } }

Java - How to make this a horizontal statement with a newline. Whenever I use System.out.println, it makes the output vertical instead of horizontal. What am I doing wrong? Program below. import java.util.Scanner; public class LabProgram {   public static void main(String[] args) {      int i;      String InputString;            Scanner sc = new Scanner(System.in);            InputString = sc.nextLine();            char[] strArray = new char[InputString.length()];            for(i = 0; i < InputString.length(); i++){            strArray[i] = InputString.charAt(i);      }            for(i = 0 ; i< InputString.length() ; i++)            if(strArray[i] >= 'a' && strArray[i] <= 'z' || strArray[i] >= 'A' && strArray[i] <= 'Z')      System.out.print(strArray[i]); (the problem line)      }}

8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…
