A Java implementation of the classic War card game for two players, built with Gradle and Java 21.
War is a simple card game typically played by two players using a standard 52-card deck. The objective is to win all the cards by having higher-ranked cards than your opponent.
The deck is shuffled and split evenly between two players (26 cards each). Each round, both players draw the top card from their deck. The player with the higher-ranked card wins both cards and adds them to the bottom of their deck. If both cards have the same rank, a "War" occurs:
Each player places 3 cards face down. Both players draw one more card face up. The higher card wins all cards in play. If there's another tie, the war continues.
The game ends when one player runs out of cards.
Cards are ranked from lowest to highest:
2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace
