Random setSeed() method in Java with Examples Last Updated : 07 Jan, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The setSeed() method of Random class sets the seed of the random number generator using a single long seed. Syntax: public void setSeed() Parameters: The function accepts a single parameter seed which is the initial seed. Return Value: This method has no return value. Exception: The function does not throws any exception. Program below demonstrates the above mentioned function: Program 1: Java // program to demonstrate the // function java.util.Random.setSeed() import java.util.*; public class GFG { public static void main(String[] args) { // create random object Random r = new Random(); // return the next pseudorandom integer value System.out.println("Random Integer value : " + r.nextInt()); // setting seed long s = 24; r.setSeed(s); // value after setting seed System.out.println("Random Integer value : " + r.nextInt()); } } Output: Random Integer value : -2053473769 Random Integer value : -1152406585 Program 2: Java // program to demonstrate the // function java.util.Random.setSeed() import java.util.*; public class GFG { public static void main(String[] args) { // create random object Random r = new Random(); // return the next pseudorandom integer value System.out.println("Random Integer value : " + r.nextInt()); // setting seed long s = 29; r.setSeed(s); // value after setting seed System.out.println("Random Integer value : " + r.nextInt()); } } Output: Random Integer value : -388369680 Random Integer value : -1154330330 Comment More infoAdvertise with us Next Article Random next() method in Java with Examples T Twinkl Bajaj Follow Improve Article Tags : Misc Java Java-Functions Java-Random Practice Tags : JavaMisc Similar Reads SecureRandom setSeed() method in Java with Examples setSeed( byte[] seed ) The setSeed() method of java.security.SecureRandom class is used to reseeds this random object.
