Write a program that prompts the user to input a sequence of characters and outputs the number of vowels. Name the program Lab10.java Write a value returning method isVowel that returns the value true if a given character is a vowel and otherwise returns false

Java Program   Write expressions that simulates rolling of two 6 sided dice  three times and display results.  (sample output below, random numbers generated from your program will be different ) Roll 1: 2 and 3 Roll 2: 3 and 6 Roll 3: 6 and 6

Instructions from your teacher: Write a program that asks the user to enter a character. Then pass the character to the following methods.   changeCase() – if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case.   Example output is given below: Enter a character  a a is equivalent to A   Note: Java represents character using Unicode encoding and ‘A’ to ‘Z’ is represented by numbers 65 to 90 and ‘a’ to ‘z’ is represented by numbers 97 to 122. So to convert ‘A’ to ‘a’ you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer. You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on. Scanner input = new Scanner(System.in); char ch =input.next().charAt(0);   If you…

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.
