Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Code in Python
Question: You are to write a Java program correctly that will prompt for and read 1 string entered by the user which may contain spaces, and display just the vowels in the string in the order they appear, and all other characters in the order they appear. Be sure to use the same format and wording as in the sample runs in the table below. The vowels are a, e, i, o and u. You can use the loop of your choice to solve the problem.

Design and implement an application that plays the Hi-Lo guessing game with numbers. The program should pick a random number between 1 and 100 (inclusive) and then repeatedly prompt the user to guess the number. On each guess, report to the user that he or she is correct or that the guess is high or low. Continue accepting guesses until the user guesses correctly or chooses to quit. Use a sentinel value to determine whether the user wants to quit. Count the number of guesses, and report that value when the user guesses correctly. At the end of each game (by quitting or a correct guess), prompt to determine whether the user wants to play again. Continue playing games until the user chooses to stop.
Write a complete Java program that performs the following tasks: 1. Ask the user to enter the last two digits of his/her student ID. 2. Break the number into two digits using arithmetic operators, then store the first and second digits in integer variables named digitl and digit2 3. Find and print the following: Note: • The product of digit] and digit2. The sum of digit1 and digit2 • The average of digit1 and digit2 • The maximum of the two numbers; digit1 digit2 using a method from the class Math.

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…

In java Develop a function that takes two integers and returns the sum of the values from the first to the second (the two inputs may be in any order). Call the function at least twice with different arguments Develop a void function PrintLineOfChar that accepts a single character and an integer. The function prints a single line of the character repeated the integer number of times. Call the function at least twice with different arguments.
#01.
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.
