If you are using numbers as Primary key, you can use java.util.Random#nextInt(int)
to generate a random number and do a database search based on that number that nextInt(3)
returned.
I think in his case, he’ll have to retrieve the database data, generate this random number and retrieve the list index corresponding to the random number
i tested java.util.Random#nextInt(int) but I will save operations like 1+1 = 2 and send these values to the program and I want these data to be searched randomly in the database
