java.util.random code example

Example 1: random java

import java.util.Random();
Random <name> = new Random();
<variable> = <name>.nextInt(<excuslive top limit>);

Example 2: float random class java

import java.util.Random;
public class Example {
   public static void main(String[] args) {
      Random rd = new Random(); // creating Random object
      System.out.println(rd.nextFloat()); // displaying a random float value between 0.0 and 1.0
   }
}

Example 3: java random seed

Random rand = new Random(System.currentTimeMillis());

Example 4: java random.nextint

public class Random {
  
  public static void main(String[] args) {
    
    Random random = new Random(long seed);
    int bound = 5;
    
    System.out.println(random.nextInt(bound));
    
  }
  
}
/*
Returns a pseudorandom, uniformly distributed int value between
0 (inclusive) and
the specified value 5 (exclusive),
drawn from this random number generator's sequence.

Example 5: java random

String id = UUID.randomUUID().toString();

Example 6: random class

Random rd = new Random(); //Create an instance of Random Class
int x = rd.Next(1,50);  //Generates a random number of int datatype between 1 and 50
Console.WriteLine(x); //Print the random number on Console
