The Sieve of Eratosthenes works by iteratively marking off multiples of each prime number starting from 2, revealing the prime numbers and eliminating the non-prime ones. The algorithm's main steps are as follows: Create a boolean array to represent the range of numbers from 2 to the given limit. Initialize all elements of the array to true, as Create an ArrayList<Integer> and then convert to an int[] at the end.. There are various 3rd party IntList (etc) classes around, but unless you're really worried about the hit of boxing a few integers, I wouldn't worry about it.. You could use Arrays.copyOf to create the new array though. You might also want to resize by doubling in size each time you need to, and then trim at the end. Das Sieb des Eratosthenes dient der Ermittlung aller Primzahlen zwischen 2 und einer Obergrenze. Hierbei werden alle Zahlen zwischen 2 und der Obergrenze zunächst als potentielle Primzahlen markiert. Die kleinste potentielle Primzahl (2) muss eine solche sein und wird ausgegeben. Dann werden alle Vielfachen dieser Zahl bis zur Obergrenze The sieve of Eratosthenes is an efficient method for computing primes upto a certain number. We first look at the algorithm and then give a program in Java for the same. Algorithm. If you want to calculate all the primes up to x, then first write down the numbers from 2 to x. Remove the first number from this list (say y) and add it to the list The Sieve of Eratosthenes is a method for finding prime numbers. It's a simple technique created by the ancient Greek mathematician Eratosthenes in the 2nd century BC. This sieve efficiently identifies prime numbers. In this article, we will discuss the Sieve of Eratosthenes in java. Also See, Multithreading in java.
