The whole purpose of my program is that a user inputs a number and according to that number it then prints out all the prime numbers leading up to the input. So for example, if the input is 20 it'll print out 2, 3, 5, .... all the way to 19. (Since 20 is not prime). This method can print the prime numbers but for some reason it is printing out 1 (1 is not prime). How can I get it to not print 1?

public boolean isPrime (int number) int prime; for (prime = 2; prime
