java - Generating reproducible IDs with UUID? -

i'm using uuid.randomuuid().getleastsignificantbits(); generate unique ids. want generate same ids every time run application in order debug code. how can that?

edit: zim-zam created class solves problem.

public class idgenerator { private static random random = new random(1); public static long getid() {     long id;     byte[] array = new byte[16];     random.nextbytes(array);     id = uuid.nameuuidfrombytes( array ).getleastsignificantbits();     return id; } } 

you can use uuid.nameuuidfrombytes(byte[] bytes) byte[] bytes random or securerandom seeded
