1. JHTP Write anisMultiple that determines, for a pair of integers, whether the second integer is a multiple of the first. The method should take 2 integer arguments and return true if the second is a multiple of the first and false otherwise.[Hint: Use the remainder operator]. Incorporate this method into an application that inputs a series of pairs of integers (1 pair at a time) and determines whether the second value in each pair is a multiple of the first.
2. (Circle Area) Write an application that prompts the user for the radius of a circle and uses a method called circleArea to calculate the area of the circle.
3. (Computer-Assisted Instruction) The use of computers in education is referred to as computer ¬assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use a Random object to produce 2 positive 1-digit integers. The program should then prompt the user with a question, such as"How much is 6 times 7?"
