36. Write a JAVA program to input two strings from the user and print all the characters present in both strings. If any character is present more than once in both the strings, then print the character again.

17.Write a Java program that prompts the user to input an integer greater than 0 which represents the size/height of the triangle shape. The program should print the following triangle shape according to the user input by alternating 'f' and '+' characters. Invalid error message must be displayed if the size is less than 1. Example: if the size of the shape = 4, then the p program should output: ! !+! !+!+! 1+1+1+1

14. Create a JAVA program to read a multi-word string from the user and then find the length of the largest word in the string. Testcase: {"This a Java Programming Problem."} Output: {11}

1. Write a Java program to implement the following: a. Display the menu which consists of list of "three choices". User has to select any one option from the list and the output should be displayed. b. In the first choice implement the concept of if-else c. In the second choice implement the concept of while loop using break statement d. In the third choice implement the concept of for loop Hint: a) Use switch statement b) Display menu should be like this: *** MENU *** 1. if-else 2. while loop using break 3. for loop

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.

1. Write a Java program that takes as input any change expressed in cents and computes the number of half-dollars, quarters, dimes, nickels, and pennies to be returned. Use as many half- dollars as possible, then quarters, dimes, nickels, and pennies, in that order. Sample output: The change you entered is 648. The number of half-dollars to be returned is 12. The number of quarters to be returned is 1. The number of dimes to be returned is 2. The number of nickels to be returned is 0. The number of pennies to be returned is 3.

ii) Write an algorithm for a program that reads a word and prints whether it is short (fewer than 5 letters). it is long (at least 10 letters). it ends with the letter y. starts and ends with the same letter.

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 <...

Write code to determine if the first character in an input string str is a lowercase character. If the first character is lowercase, output "issue", otherwise output "no problem". in java
