Write a program that prompts the user to input a sequence of characters and outputs the number of vowels. (Use the function isVowel written in Programming Exercise 2.) Your output should look like the following: There are # vowels in this sentence. . where # is the number of vowels.

Program 2: Write a program that asks the user for a word or phrase. Check to see if it is a palindrome. A palindrome is a word that is spelled exactly the same forward and backwards such as radar or noon. Your program must also take case into account. If the user types Radar, it must still return that it is a palindrome. Do not worry about palindromes with spaces. You do not need to put any code in static methods, you do not need to worry about try/catch blocks, and you do not need to make the program run more than once. Test values that I will use in class:   Noon palindrome tacocat palindrome Hello not a palindrome   in java

a. Write a program that reads your id and full name and display. And also display the index of first letter and last letter of your full name. b. Modify above program, Declare a string course, let your program read course from user, check if course is not equal to comp2002, clear the string otherwise concatenate course and " Computer Science Department". C. Modify above program declare a string college="". If string college is empty then assign a new string "College of Science".

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
