Write an application that reads an integer value from the user and prints the sum of all even integers between 2 and the input value, inclusive. Print an error message if the input value is less than 2. Use Java.  Sample Run Examples:  Example 1: the user enters 14 Output: Sum: 56 Example 2: the user enters 1 Output: Error number must be greater than

in Java Tasks Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 3. The computer's choice is displayed. Tasks 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) C. If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps…

There are five errors in this code. Correct the errors and make the code work.

Write an application that prompts a user for the number of years the user has until retirement and then the amount of money the user can save annually. If the user enters 0 or a negative number for either value, reprompt the user until valid entries are made. Assume that no interest is earned on the money. Display the amount of money the user will have at retirement.   import java.util.Scanner; public class RetirementGoal {    public static void main (String[] args)    {       // your code here    } }
