I am trying to create a shuffle class for the cards dynamic array I the cards array contains strings for suit and rank and int for value
here is where im getting the error required: variable found: value
private void Shuffle() {
for (int p = 0; p <1000; p++) {
int rand1 = (int) (Math.random()* 52);
int rand2 = (int) (Math.random()*52);
Card Temp = cards.get(rand1);
cards.get(rand1) = cards.get(rand2);
cards.get(rand2) = Temp;
}
}
I believe you are trying to shuffle cards 1000 times randomly, soo the most simplistic approach IMHO would be something like this (assuming your cards are in ArrayList)
private void Shuffle() {
for (int p = 0; p < 1000; p++) {
int rand1 = (int) (Math.random() * 52);
int rand2 = (int) (Math.random() * 52);
Card card1 = cards.get(rand1);
Card card2 = cards.get(rand2);
cards.set(rand1, card2);
cards.set(rand2, card1);
}
}
I believe, cards is of type List. cards.get(index) returns an object of the Card. An object can be assigned to a reference and not to another object. Hence, cards.get(rand1) = cards.get(rand2) is like assigning an object to another object. It is similar to writing 1=2.
