查找流中满足条件的第一个元素，直到该元素

def find_first_element(stream, condition):
    for element in stream:
        if condition(element):
            return element
    return None

# 示例用法
stream = [1, 2, 3, 4, 5]
condition = lambda x: x > 3
result = find_first_element(stream, condition)
print(result)  # 输出: 4

import java.util.List;

    public static <T> T findFirstElement(List<T> stream, Condition<T> condition) {
        for (T element : stream) {
            if (condition.test(element)) {
                return element;
            }
        }
        return null;
    }

    // 示例用法
    public static void main(String[] args) {
        List<Integer> stream = List.of(1, 2, 3, 4, 5);
        Condition<Integer> condition = x -> x > 3;
        Integer result = findFirstElement(stream, condition);
        System.out.println(result);  // 输出: 4
    }
