- Intro to Java Instuctions: Design and implement a program that reads a series of 10 integers from the user and prints their average For each of the 10 numbers input from the user: one at a time, prompt the user to enter a number. Then read input from the user as a string. Attempt to convert it to an integer using the "Integer.parseInt" method. If the process throws a "NumberFormatExeption", print an appropriate error message and prompt the user for the number again. Continue prompting and reading in number until 10 valid integers have been read Print "The average is" and then print the average of the 10 numbers Code: import java.util.Scanner; public class Lab1MainClass { public static final int VALUES_TO_READ = 10; public static void main(String[] args) { // local variables int[] values = new int [VALUES_TO_READ]; double average; Scanner scan = new Scanner(System.in); int values Read = 0; // how many numbers the user has given us, a count of where we are String userInput; // read…Java Lab 401120 Lab 7 Dec 21, 2020 1.

- JAVA Notes: all program codes should be written with method/s separated from the main() structure. Use a separate code files for each. Programming Problems: 1. Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, otherwise return false. Also write a program to test your method. 2. Write a program that prompts the user to enter a sequence of characters and output the number of vowels and consonants separately. (use the method isVowel written in problem 1). 3. Write a program that output inflation rates for two successive years and whether the inflation rates are increasing or decreasing. Ask the user to input the current price of an item and its price, one year and two years ago. To calculate the inflation rate for a year, subtract the price of the item for that year and from the price of the item from one year ago and then divide the result by the price a year ago.

If the PIN is not valid print an error message “INCORRECT PIN. TRY AGAIN.” and let the user enter the PIN again. But the user only has 3 tries to enter the correct PIN. If the user enters the wrong PIN for his/her 3 tries then print “YOU HAVE RUN OUT OF TRIES. ACCOUNT LOCKED.” And if the user enters the valid PIN within the 3 tries print “PIN ACCEPTED. YOU NOW HAVE ACCESS TO YOUR ACCOUNT.” Use a while loop to prompt the user to enter a valid PIN. Do not forget to print a prompt for the user asking to enter the PIN. Create a class named PinLockout which will have the main method. All your code goes inside the main method. Sample input and output: Sample 1: ENTER YOUR PIN: 2345 INCORRECT PIN. TRY AGAIN. ENTER YOUR PIN: 2356 INCORRECT PIN. TRY AGAIN. ENTER YOUR PIN: 7564 YOU HAVE RUN OUT OF TRIES.…
