1- Write a program that reads a character and prints it only if it is 'y' or 'Y' (Simulation of If-Else then structure). emulator screen (80x25 chars) The input character is not "y" or "Y". emulator screen (80x25 chars)

PrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output…

Java use While loop: Write a program that  creates two random numbers, ask user to finde the sum of them, takes the user input, check if it true, if so print " You got it ", if not prints " try again ".

LAB: Loops: Output range with increment of 10   Write a program that reads two integers as input, and outputs 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.
