what is random in java 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: how to create a random number in java

import java.util.Random;

class scratch{
    public static void main(String[] args) {
        Random rand = new Random();
        System.out.println( rand.nextInt(5) );
        //prints a random Int between 0 - 4 (including 0 & 4);
    }
}

Example 3: funzione random in java

int n = (int) (Math.random() * 51);

Example 4: 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
