java random usagee 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: 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 usage

import java.util.Random;

Random rndm = new Random();
int mnmbr = 10;

int rndNumber = rndm.nextInt(mnumber) + 1;

System.out.println(rndNumber);
