Write a Java Program which generates a random number

In Java, you can generate random numbers using the java.util.Random class or the Math.random() method. Here are examples of both approaches:

Program 1 :(How to Generate Random Number in Java Using java.util.Random class)

import java.util.Random; public class RandomNumberGenerator { public static void main(String[] args) { // Create a Random object Random random = new Random(); // Generate a random integer int randomNumber = random.nextInt(); // Generates a random 32-bit integer System.out.println("Random Integer: " + randomNumber); // Generate a random integer within a specific range (e.g., between 1 and 100) int minRange = 1; int maxRange = 100; int randomInRange = random.nextInt(maxRange - minRange + 1) + minRange; System.out.println("Random Integer in Range: " + randomInRange); // Generate a random double between 0 (inclusive) and 1 (exclusive) double randomDouble = random.nextDouble(); System.out.println("Random Double: " + randomDouble); } }

Program 2 : (How to Generate Random Number in Java Using Math.random() method)

public class RandomNumberGeneratorMath { public static void main(String[] args) { // Generate a random double between 0 (inclusive) and 1 (exclusive) double randomDouble = Math.random(); System.out.println("Random Double: " + randomDouble); // Generate a random double within a specific range (e.g., between 1 and 100) int minRange = 1; int maxRange = 100; double randomDoubleInRange = Math.random() * (maxRange - minRange + 1) + minRange; System.out.println("Random Double in Range: " + randomDoubleInRange); // If you need an integer value, you can cast the result int randomIntInRange = (int) randomDoubleInRange; System.out.println("Random Integer in Range: " + randomIntInRange); } }

Keep in mind that Math.random() returns a pseudorandom double value between 0.0 (inclusive) and 1.0 (exclusive). If you need integers or a more flexible and configurable random number generation, using java.util.Random might be a better choice.
