Randomly choose between two ints

[Wayslili 0]

How would i get it to randomly choose between two integers? For example, i want it to randomly to choose between either 3 or 5.

i dont want to choose between the two numbers, i want it to choose only from the set of two numbers.

2 ways:

1) Through an array using the Random class.

Random random = new Random();

int randomPickedNumber = arrayName(random.nextInt(arrayName));

 

2) Through Lists using Collections.shuffle();

ArrayList<Integer> listName = new ArrayList<Integer>();

Collections.shuffle(listName);

int randomPickedNumber = listName.get(0);

 

 

You can also turn the array into a list using

Collections.asList(arrayName); 

or turn the list into an array using

Arrays.toArray(listName);

 

Also there's a way to pick between 2 numbers is by chance, like the following:

int chance = Calculations.random(1,100);

int chosenNumber;

if(chance <=50) chosenNumber = firstInteger;

else chosenNumber = secondInteger;

 

 

 

hope this helps

Sorry, I misunderstood. Defiled has provided some good examples, but to add an additional one. If you only want to have two selection choices:

private Random random = new Random();


int randomOfTwoNumbers = random.nextBoolean() ? 3 : 5); // replace 3 and 5 with the numbers you want
