查找时差 [英] Find Time Difference

问题描述

我想在 java 中找到时差，这样我就可以在会话过期时创建新会话，否则会分配新的时间.

I want to find time difference in java so that I can create new session if session expires else will assign new time.

推荐答案

Returns Time Diffrence in Seconds :




long elapsed_time = 0L;
    java.util.Date startTime = null;
    java.util.Date endTime = null;
    double fsec = 0L;
    String rSec = "";   

        startTime = new java.util.Date();

        <--------Some Operation----->

        endTime = new java.util.Date();
        elapsed_time = endTime.getTime() - startTime.getTime();
        fsec = (elapsed_time) / 1000.00;
        rSec = Double.toString(fsec);
        rSec = rSec + " Sec";
