Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 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. For coding simplicity, output a space after every integer, including the last.

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. 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. For coding simplicity, output a space after every integer, including the last.
Write a program which takes an input from the user, if the input is 1, calculate the area of the circle, if the input is 2 calculate the area of Rectangle, if input is 3 calculate the area of the square, otherwise display "Wrong Input".
Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is 93, the output is: 93 92 91 90 89 88 Ex: If the input is 77, the output is: 77 Ex: If the input is not between 20 and 98 (inclusive), the output is: Input must be 20-98 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, ..., 88), as that approach would be cumbersome for large ranges.

Write a program that reads a person’s name in the following format: first name, then middle name or initial, and then last name. The program then outputs the name in the following format:last name, first name. middle initial.For example the inputMary Average User should produce the outputUser, Mary A.Your program should work the same and place a full stop after the middle initial even if the input did not contain a full stop. Your program should allow for users who give no middle name or initial. In that case, the output of courses contains no middle name or initial. For example, the inputMary User should produce the outputUser, MaryYour program should also accept names in lowercase, uppercase or a mix of lowercase and uppercase, and display that in the correct format, e.g. if the input ismArY average USERshould produce the outputUser, Mary A.Use C-strings and assume that each name is at most 20 characters long.Hint: it may be easier to use 3 C-strings.

Use JAVA to create a card game with in which the dealer shuffles the deck and deals 13 cards out of the 52 to the player. If the player sorts her hand and it includes a king of heart, then in response, the dealer should write on the console, "You won!" if not then then "You loose again." Make sure the cards are randomized to get different outputs. Also, create a unit test for the win and loose cases.
