Using a conditional expression, write a statement that increments numUsers if updateDirection is 1, otherwise decrements numUsers. Ex: if numUsers is 8 and updateDirection is 1, numUsers becomes 9; if updateDirection is 0, numUsers becomes 7. Hint: Start with "numUsers = ..". 1 import java.util.Scanner; 2 3 public class UpdateNumber0fUsers { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int numUsers; int updateDirection; 4 7 8 9. numUsers scnr.nextInt(); %3D 10 updateDirection scnr.nextInt((); %3D 11 12 /* Your solution goes here */ 13 Create a conditional expre and non negative otherwi System.out.println("New value is: } + numUsers); %3D 14 is negative. 15 import je.util.Scanner 16 }

The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.
- Java Overview In this task, you should try using the Scanner class to read data from the keyboard. This data should be stored in variables in your program and then printed on screen. Task You should write a class called Story that should include a main method. This programs should create a fairy tale for a child. The program is based on a completed story, but some words must be replaced with such as the user may enter. The fairy tale you are going to based on are the following: The little ant (1) There was once a small, small ant that lived with its (2) and its (3) siblings in an anthill, by a large (4) in the forest. The little ant is called (1). For the most part, (1) and his siblings used to work on carrying (5) and (6) to the stack, but today it was (7), so (1) was free. The words that are crossed out are the words that your program should ask the user for. In total, there are seven entries the user must make. The program must save these entries in separate variables and then…Write an expression that continues to bid until the user enters 'n'. 367012.2549490.qx3zqy7 1 import java.util.Scanner; 2 3 public class AutoBidder { public static void main (String [] args) { Scanner scnr 4 = new Scanner(System.in); char keepBidding; int nextBid; 7 8 nextBid 0; 'y'; 10 keepBidding 11 *) { while (* Your solution goes here nextBid + 3; 12 13 nextBid System.out.println("I'll bid $" + nextBid + "!"); System.out.print("Continue bidding?
