java获取当前时间戳加三分钟

要在Java中获取当前时间戳并加上三分钟，你可以使用以下代码：

import java.time.Instant;

public class Main {
    public static void main(String[] args) {
        // 获取当前时间戳
        long currentTimestamp = Instant.now().toEpochMilli();

        // 加上三分钟
        long threeMinutesLaterTimestamp = currentTimestamp + 3 * 60 * 1000;

        System.out.println(threeMinutesLaterTimestamp);
    }
}

这段代码使用了Java 8中的`Instant`类来获取当前时间戳，并利用基本的数学运算将时间戳增加了三分钟。最终输出的结果就是当前时间戳加上三分钟的值。<span class="em">1</span><span class="em">2</span>
