Java 计时

 

long start_time = System.currentTimeMillis();

 

long elapsedTimeMillis = System.currentTimeMillis()-start;

 

float end_time = (System.currentTimeMillis() - start_time)/1000F;              

 

System.out.println("Map finished in "+ end_time+" seconds");

 

 

// Get time in minutes
float timeMin = elapsedTimeMillis/(60*1000F);

// Get time in hours
float timeHour = elapsedTimeMillis/(60*60*1000F);

// Get time in days
float timeDay = elapsedTimeMillis/(24*60*60*1000F);
