Java but I need it with while loop
Step by step
Solved in 3 steps with 3 images
- Write a Java program for Zeller’s Algorithm, which can be used to determine the day of the week for any date in the past, present, or future. The program should request the user to enter the date values (month, day, and year). Next, the program should apply the algorithm (see below), and display the appropriate day of the week. The program should loop until the user enters 0 for a month. Use the pre-test while loop with sentinel-value structure while (month!=0). In addition, validate that the month is between 0 and 12; and that day is between 1 and 31. Use the while loop structure for error checking.Write a Java program that inputs three integer variables (called a, b, and c) that represent the length of the sides of a triangle. Your program should store the type of the triangle in an enumeration variable (called type), and display the value of the variable type. Here are the steps to follow: 1- Defines an enumeration to represent the different triangle types: EQUILATERAL, ISOSCELES, SCALENE, and ERROR. The type ERROR is added in case that the value of any triangle sides is less than or equal to zero. 2- Declare then input the three integer variables a, b, and c using a scanner object called keyboard. 3- Declare the enumeration variable type. 4- Determine the type of the rectangle (i.e. Assign a value to the variable type) 5- Print the value of the variable type. NOTE: If all sides are equal, the rectangle is EQUILATERAL. If only two sides are equal, the rectangle is ISOSCELES, otherwise the rectangle is SCALENE. Note that the type of the rectangle should be ERROR if the length…Write a program that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence.
- Use Java Implement a game of Pig where the user plays against a "hold at 20 or goal" computer player that rolls until a 1 ("pig") is rolled, or the turn total is greater than or equal to 20, or the score plus the turn total is greater than or equal to 100. The first player is chosen randomly. An empty input (i.e., Enter) indicates that the user wishes to roll. Any entered line of non-zero length indicates that the user wishes to hold. Before the game, randomly select which player the user will be, and print the line "You will be player #.", where # is the user's player number. Then, print an instruction line "Enter nothing to roll; enter anything to hold." Before each turn, print a line with "Player 1 score: " and player 1's score. Print another line with "Player 2 score: " and player 2's score. Finally, print a line with "It is player #'s turn.", where "#" is replaced by the current player number. Play starts with player 1 and then alternates. For each roll, print a line with…Write a program in Java to take an infix mathematical expression. The expression will contain single- or double-digit numbers, ‘+’, ‘-‘, ‘*’, and ‘/’ operators, and parenthesis. First check the validity of the expression with respect to the position of opening and closing parenthesis. If the expression is not valid then display appropriate message, otherwise, convert that infix expression to corresponding postfix expression, evaluate that postfix expression and print the final result. You can use relevant Java built-in classes in your code. The sample inputs/ outputs are given below: Sample inputs and outputs: (User’s inputs are shown in bold) Sample 1 Enter the mathematical expression: 15*(8–3*2)+16/4) The expression is invalid Sample 2 Enter the mathematical expression: 15*(8–3*2)+16/4 The postfix expression: 15 8 3 2 * - * 16 4 / + The final result: 34Write a program in Java to take an infix mathematical expression.

- java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.) Design: (Describe the major steps for solving the problem.) Coding: (Go over your code step by step) Testing: (Describe how you test this program). In other words run your code with sample outputs.Write a Java program that displays a shape representing capital letter of N as shown in the examples below. The program should ask the user to enter an integer number size greater than or equal to 4 representing the size of the letter N in terms of number of rows and columns. Appropriate error message should be displayed if the user input for size is invalid.Please &-. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ik.?
- Write a program that takes a positive integer as the height of the triangle and prints an alphabetical triangle, using lowercase English letters as shown below. Each subsequent row of the triangle should increase in length by two letters. Make sure your program validates the user input. If the user does not input a positive integer, print "Invalid input."Im stuck on this java code. The code is supposed to ask user for a string. Characters that are number, are doubled and replaced with the sum. The characters that are upper are replaced with lower and lower are replaced with upper. It should keep asking user for string until user input Q to end the program. example 1: original: 3rD converted: 6Rd ex 2: original: 6sJ converted: 3Sj (when a value is doubled and its than 9, the two digits are added. so 6 * 2 is 12. And then add the two digits. so 1 + 2 = 3.) I'm having problem with the code that its not reading where it replace the lower to upper and vice versa. this is my code so far: import java.util.Scanner;public class Convert {public static void main(String[] args) {Scanner input = new Scanner(System.in);String original, converted;while (true) {System.out.print("Original String (input):");original = input.nextLine();if (original.equals("q") || original.equals("Q")) {break;}char[] chars = original.toCharArray();for (int i = 0; i <…I need help with this question Write a Java program that prompts the user to enter a word then prints the number of vowels in thisword.
