Java 鸡兔同笼问题解法：代码示例与解析

public class ChickenRabbitPen { private int chickenCount; private int rabbitCount; private int totalCount;

public ChickenRabbitPen(int totalCount, int totalLegs) throws Exception {
    if (totalLegs % 2 != 0) {
        throw new Exception('总腿数必须为偶数');
    }
    this.totalCount = totalCount;
    this.rabbitCount = (totalLegs - totalCount * 2) / 2;
    this.chickenCount = totalCount - rabbitCount;
}

public int getChickenCount() {
    return chickenCount;
}

public int getRabbitCount() {
    return rabbitCount;
}

public static void main(String[] args) {
    try {
        ChickenRabbitPen pen = new ChickenRabbitPen(10, 28);
        System.out.println('鸡的数量为：' + pen.getChickenCount());
        System.out.println('兔的数量为：' + pen.getRabbitCount());
    } catch (Exception e) {
        System.out.println(e.getMessage());
