There is 50 odd numbers between 0 and 100. To select one of them you can do. int n = random.nextInt(50); to get the n-th odd number you can. int odd = n * 2 + 1; Putting it all together. int odd = random.nextInt(max / 2) * 2 + 1;

Aug 1, 2018 · This is the method what you need to use: public static int generateRandomOddNumbersWithinRange(final int min, final int max) { Random random = new Random(); int randomNumber = random.nextInt((max - min) + 1) + min; if ((randomNumber & 1) != 0) { return randomNumber; } return randomNumber - 1; }

You can use streams and wrap it up in a helper method for ease of use if you like: import java.util.Random; public static IntStream randomOdds(int from, int upTo) { return new Random().ints(from/2, upTo/2).map(n -> 2*n + 1); } Usage: randomOdds(1, 1000).limit(20).forEach(System.out::println);

Jan 4, 2025 · Java provides three ways to generate random numbers using some built-in methods and classes as listed below: java.util.Random class; Math.random method : Can Generate Random Numbers of double type. ThreadLocalRandom class; 1) java.util.Random

You can use Math.random() method to generate a random number. To get more control over the random number, for example, if you only want a random number between 0 and 100, you can use the following formula:

Mar 17, 2025 · In this section, we will create a Java program to display odd numbers from 1 to 100. To learn the Java odd number program, you must have the basic knowledge of Java for loop and if statement. We can use different Java loops to display odd numbers: Using Java for Loop; Using nested-if Statement; Using while Loop; Using Java for Loop

Apr 16, 2019 · In this example, we will write a Java program to display odd numbers from 1 to n which means if the value of n is 100 then the program will display the odd numbers between 1 and 100. In the following example we have provided the value of n as 100 so the program will print the odd numbers from 1 to 100.

In this tutorial, we shall write Java Programs that print all odd numbers from starting of 1, up to the given limit or maximum. You can use looping techniques, to iterate for each odd number until a threshold, or maximum.

Mar 31, 2017 · In Java 1.7 or later, I would use ThreadLocalRandom: import java.util.concurrent.ThreadLocalRandom; // Get odd random number within range [min, max] // Start with an odd minimum and add random even number from the remaining range public static int randOddInt(int min, int max) { if (min % 2 == 0) ++min; return min + 2*ThreadLocalRandom.current ...

Oct 14, 2022 · Java program to print odd numbers from 1 to 100: This post will show you how to print odd numbers in Java from 1 to 100 or in a given range. With this program, you will learn how to read user inputs in Java, how to use a loop and how to print output on the console. How to find if a number is odd:
