Java Programming: Question 12 Not sure how to do this question. Help of any input and output would be appreciated.

This is the question - Write an application that accepts any number of String values from a user until they enter zzz or have entered 15 strings, and display them in ascending order. This is the code I have but it is wrong becuase I didn't get a single check right -  import java.util.*; public class StringSort2 {     public static void main(String[] args) {         // Write your code here         Scanner sc = new Scanner(System.in); String s = ""; System.out.print(""); ///loop works until string input is zzz or string length is greater than 15 while (true){     String input = sc.nextLine();     if(input.equalsIgnoreCase("zzz") || input.length()>15)         break;         s=input; }   } }

JAVA PPROGRAM ASAP   Please create  this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade.    Chapter 9. PC #8. 8. Sum of Numbers in a String (page 610) Write a program that asks the user to enter a series of numbers separated by commas. Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty.   Test Case 1     Enter a series of numbers separated only by commas or type QUIT to exit:\n7,9,10,2,18,6ENTERThe sum of those numbers is 52.00\nEnter a series of numbers separated only by commas or type QUIT to exit:\nENTEREmpty string.\nEnter a series of numbers separated only by…

In Java:  Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
