randomsetbuilder's Introduction

RandomSetBuilder

RandomSetBuilder - is a class that builds you set of random numbers from the range

How to

Creating object

To create an object of RandomSetBuilder use parameters min, max and seed. The range will be from min to max - 1.
Parameters min and seed are optional. By default min = 0 and seed = System.currentTimeMillis().

Code example:

RandomSetBuilder randomSetBuilder = new RandomSetBuilder(0, 10);

Adding numbers to the set (building)

append(int count)

To add some numbers to the set use append(int count) method. If count is more than number of integers that can be added, than only available number of integers will be added.

Code example:

RandomSetBuilder randomSetBuilder = new RandomSetBuilder(0, 10);

randomSetBuilder.append(3);   // add 3 unique integers from the range [0, 9], 7 left unused
randomSetBuilder.append(2);   // add 2 unique integers from the range [0, 9], 5 left unused
randomSetBuilder.append(100); // add 5 unique integers from the range [0, 9], 0 left unused
randomSetBuilder.append(100); // add 0 unique integers from the range [0, 9], 0 left unused

appendAll()

If you want to add all the rest unused integers use appendAll() method.

Code example:

RandomSetBuilder randomSetBuilder = new RandomSetBuilder(0, 10);

randomSetBuilder.append(3);    // add 3 unique integers from the range [0, 9], 7 left unused
randomSetBuilder.append(2);    // add 2 unique integers from the range [0, 9], 5 left unused
randomSetBuilder.appendAll();  // add 5 unique integers from the range [0, 9], 0 left unused

Getting building result

As the result you can get List, Set, Queue, Deque or integer array

Code example:

Set<Integer> randomSet = randomSetBuilder.toSet();
List<Integer> randomList = randomSetBuilder.toList();
Queue<Integer> randomQueue = randomSetBuilder.toQueue();
Deque<Integer> randomDeque = randomSetBuilder.toDeque();
int[] randomArray = randomSetBuilder.toArray();
