Homework 3: Input Validation 1 Objectives control structures console-based user input using Scanner class writing complete programs using two classes: client and supplier 2 User Interface Specification This is a console-based I/O program. Display should go to System.out (print or println) and the program will get user input using the Scanner class. The flow of execution should be as follows: When the program starts, display a one-line introduction to the user Display a menu with 5 options 1. validate zip...

In java, write a program that gets 10 integer numbers from the user using user input, and then calculates and display the sum of the numbers that have been read. Program Requirements: Write the program in three versions with three loops. Put all three loops in the main method of your source code. version1: use a while loop. version2: use a do-while loop. version 3: use a for loop. For each version, use a loop to input 10 int numbers from the user...

(java) Write a While loop that prompts the user for only even numbers. Keep prompting the user to enter even numbers until the user enters an odd number. After the loop ends, print the sum of the numbers. Do not include that last odd number. You should not store the numbers in an array, just keep track of the sum. Make sure to use a break statement in your code. You may assume that a java.util.Scanner object named input has...

(Java) Rewrite the following exercise below to read inputs from a file and write the output of your program in a text file. Ask the user to enter the input filename. Use try-catch when reading the file. Ask the user to enter a text file name to write the output in it. You may use the try-with-resources syntax. An example to get an idea but you need to have your own design: try ( // Create input files Scanner input...

A class Scanner in Java can be used to get user input and its methods can be used after the following statement is executed: Scanner input = new Scanner(System.in); One of its methods nextDouble() returns the next double value from the keyboard. Now you are requested to write a method enterHeight() which displays the message "Input height: " and uses the method input.nextDouble() to get the user input. The process should be repeated until the input is non-negative. Finally the...
