java random class code example

Example 1: java random number

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Example 2: random java

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

Example 3: 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 4: java random seed

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

Example 5: java random

int nombreAleatoire = Min + (int)(Math.random() * ((Max - Min) + 1));

Example 6: java random

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