: Write a Java program to find and print all prime numbers between 1 and a given positive integer 'n'. Your program should take 'n' as input from the user and then output all the prime numbers between 1 and 'n'. A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself. Example: Input: n = 20 Output: 2, 3, 5, 7, 11, 13, 17, 19 You can use a method to check if a number is prime or not, and then iterate through the numbers from 1 to 'n' to find the prime numbers..
ISP-Java Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. For coding simplicity, output a space after every integer, including the last. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first.
Write an application that reads an integer value from the user and prints the sum ofall even integers between 2 and the input value, inclusive. Print an error message ifthe input value is less than 2. Use Java. Sample Run Examples: Example 1:the user enters 14Output: Sum: 56Example 2:the user enters 1Output: Error number must be greater than 1
This is the question: only using the "while loop" Write a java program which asks the user to enter name and age and calls the following methods: printName(): Takes name as parameter and prints it 20 times using a while loop. printAge(): Takes age as parameter and prints all the numbers from 1 upto age. Write a java program that will print first 10 multiples of 3 in a single line.
Write a program to ask user to enter number of codes. Assign a letter for each code and possibility. Create a Huffman code for each letter.Please write program in java
Write an application that asks a user to type an even number or the sentinel value 999 to stop. When the user types an even number, display the message “Good job!” and then ask for another input. When the user types an odd number, display an error message, "x is not an even number", and then ask for another input. When the user types the sentinel value 999, end the program. import java.util.*; public class EvenEntryLoop { public static void main (String args[]) { // Write your code here } }
in java Use scnr.nextInt() to read integers from input into inputData until 1000 is read. For each remaining integer read before 1000, if the integer is non-positive, output the integer followed by a newline and add the integer to sumOfSelected. Ex: If the input is -23 13 -5 -4 -17 1000, then the output is: -23 -5 -4 -17 The sum of all non-positive values is -49 Note: The sentinel value is 1000.
Write a java program that simulates rolling a pair of dice 10,000 times and counts the number of times doubles (two of the same number) are rolled for each different pair of doubles. Use a loop, if-else statements and a random number generator. After the 10,000 iterations, print out the following results: Value of the first die Value of the second die Total number of dice rolls Number of snake eyes rolls (ones) Number of double two rolls Number of double three rolls Number of double four rolls Number of double five rolls Number of double six rolls
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…
