4. Write a JAVA program to take input a positive integer n from the user and print the number of digits in the sum of all digits of the number n.

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.

Write a program to compute the sum of the first N Fibonacci numbers, where N is an integer that is input by the user. Once it computes the sum, the program will prompt the user for a new value of N. The program will exit if the user enters a non-integer number or string (such as "quit") instead of an integer. Language: Java The first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Use For loop at least once, can use while loops. Sample Output: Welcome to the Fibonacci AdderTo quit, enter a non-integer number or string How many Fibonacci numbers should be summed? >> 10The sum of the first 10 Fibonacci numbers is: 88 How many Fibonacci numbers should be summed? >> xxx Thank You for Using the Fibonacci Adder

Use Java Code- Given a string represent a 10 digit phone number, output the area code, prefix and line number using the format (800) 555-1212 Ex. If the input 8005551212 Output (800) 555-1212

Write a program that reads an unspecified number of integers, determineshow many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number.

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.

2. For any 5 digit integer, for example 13092, write Java code to display each of the 5 digits individually and to print the total of the five digits
