1. Prime.java Write a program to print all the prime numbers below a certain given number. A prime number is defined as a number that can only be divided by 1 and itself. For example, 2, 3, 17 and 41 are all prime numbers. Make sure your program conforms to the following requirements: a. Using Scanner class, accept the upper limit from the user (as an integer). b. You can assume the user input will be positive and smaller than INT MAX. c. Using for loop, go from 1 to the number. If you happen to find a number that is prime, print it. The input and output should match the sample run perfectly. Sample run 1: Enter the upper limit: 25 The prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23 Sample run 2: Enter the upper limit: 70 The prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67
