- There are five errors in this code. Correct the errors and make the code work. Explain what are the errors found. import java.util.Scanner; //Testing.java //Displays running total of numbers in lines of standard //input correct to two decimal places. //Uses an out of range number (100) to quit. public class TWODPS{ public static void main (String [] args) { Scanner input new Scanner (System.in); double total=0; boolean flag=true; System.out.println ("Use an out of range entry 100 to quit."); while (flag) { System.out.println ("Enter a number on a line:"); double d = input.nextDouble (); if (outofRange (d) ) { flag=false; else{ dispTwoDPs ("The number value is: ",d); total = total + d; dispTwoDPs ("The total is: ",total); System.out.println (); System.out.println ("Next."); } //end of else }//end of while System.out.println ("You quit."); }//end of main static boolean outOfRange (double d) { if (d>-100) return true; if (d>100) return true; return false; }arrow_forwardGreatest Common Divisor Two integers A and B have the greatest common divisor which is the largest positive integer that divides A and B, evenly, without a remainder. One way to find the Greatest Common Divisor is to consider the prime factors for A = 372 and B = 84 as shown below. 372 223 * 31 84 22*3*7 GCD (372,84) = 2²*3= 12 In a well-documented Python program, hmwk3Q3.py, query the user for two integers. Use a while-loop to find the remainder R when dividing A by B.Replace the value of A with the value of B and replace the value of B with the value of R.Continue this process within the while-loop until the value of B is zero. At that time the value of A will be the GCD. In a comment, provide the response to your program when A= 98,025,733,547 and B = 2,345,109,894,323.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
- Questio Write a program that receives a series of characters from the user, the program stops if the user enters the same character two consecutive times, the program should display the number of entered characters at the end of the program (the last duplicated character is counted only once): Sample Run: Enter your characters: asbnmkrr we got 7 characters please wirte it in java using loops please answer it in java using netbeans.arrow_forwardIN JS PROGRAMMING LANGUAGE Your local bank has decided to upgrade its ATM machines by incorporating motion sensor technology. The machines now interpret a series of consecutive dance moves in place of a PIN number. Create a program that converts a customer's PIN number to its dance equivalent. There is one dance move per digit in the PIN number. A list of dance moves is given in the code. Examples danceConvert("0000") danceConvert("3856") ["Shimmy", "Shake", "Pirouette", "Slide"] → ["Slide", "Arabesque", "Pop", "Arabesque" ] -arrow_forwardstrobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Find all strobogrammatic numbers that are of length = n. For example, Given n = 2, return ["11","69","88","96"]. def gen_strobogrammatic(n): Given n, generate all strobogrammatic numbers of length n. :type n: int :rtype: List[str] return helper(n, n) def helper(n, length): if n == 0: return [™"] if n == 1: return ["1", "0", "8"] middles = helper(n-2, length) result = [] for middle in middles: if n != length: result.append("0" + middle + "0") result.append("8" + middle + "8") result.append("1" + middle + "1") result.append("9" + middle + "6") result.append("6" + middle + "9") return result def strobogrammatic_in_range(low, high): :type low: str :type high: str :rtype: int res = count = 0 low_len = len(low) high_len = len(high) for i in range(low_len, high_len + 1): res.extend(helper2(i, i)) for perm in res: if len(perm) == low_len and int(perm) int(high): continue count += 1 return…arrow_forward
- Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);arrow_forwardJAVA 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…arrow_forwardХ3: inlTol0 Write a function in Java that implements the following logic: Given a number n, return true if n is in the range 1..10, inclusive.
