比較for循環中的值

Question

我正在做2個隨機卡生成器。 我想知道哪個更高。 在以下示例中，如何將當前值與先前值進行比較？

 for (int i = 0; i < 2; i++){
    String suit = suits[deck[i] / 13];
    String rank = ranks[deck[i] % 13];
    System.out.println("You have the " + rank + " of " + suit);                 
}

Answer 1

String previousValue = null;
for(...) {
    String currentValue = ...;

    // you can now compare previous with current, watch out for unset (null)
    if( previousValue != null && currentValue (?) previousValue ) {...}

    //... any further processing

    // following is the last line in your loop, so it is set for next loop iteration
    previousValue = currentValue;
}
