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:\n
7,9,10,2,18,6ENTER
The sum of those numbers is 52.00\n

- The String class is a mutable class. O True O Falsearrow_forwardForms 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.arrow_forwardCcxxarrow_forward
- Active GMatrix S1C17 Question Write a python program that takes a string as an input from the user and checks if there are any groups of THREE consecutive vowels, The input string will be a random combination of small letter and capital letter characters. Then replace all the three consecutive vowels with # character. So, the presence of such a group is ensured. Sample Input1 FJAUjsioAstu Sample Output 1 FJAUJS###stu Explanation 1: Since i, 'o' and 'A' are three vowels and they appear in the input string consecutively. So all those three characters are replaced by # character in the output. Sample Input2: asoUiBPqteeastW Sample Output 2 as###BPqt###stw Explanation 2 Here, 'o', U' and i' form a group of three consecutive vowels and again 'e', 'e', and 'a' form another such group. So all of them are replaced by # character. But the single 'a' at the very beginning is not replaced since it is not included in any group of three. PELL ...

PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTERarrow_forwardString personName is read from input. Output personName left aligned with a width of 6, followed by " Taylor". End with a newline. Ex: If the input is Juno, then the output is: Juno Taylorarrow_forward4. Word Separator:Write a program that accepts as input a sentence in which all of thewords are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses. *python codingarrow_forward

Morse Code Converter Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes. Write a program that asks the user to enter a string, and then converts that string to Morse code and prints on the screen. Use hyphens for dashes and periods for dots. The Morse code table is given in a text file morse.txt. When printing morse code, display eight codes on each line except the last line. Codes should be separated from each other with one space. There should be no extra spaces at the beginning and at the end of the output. Uppercase and lowercase letters are translated the same way.

If there is more than one word print only the first. Your print statement should read: "The shortest word is x" Where x = the shortest word. The word should be all uppercase.arrow_forwardPrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output…arrow_forward
