有时,您可能需要以毫秒为单位测量时间点。因此,让我们再次重写上面的示例-
import java.util.*; public class DiffDemo { public static void main(String args[]) { try { long start = System.currentTimeMillis( ); System.out.println(new Date( ) + "\n"); Thread.sleep(5*60*10); System.out.println(new Date( ) + "\n"); long end = System.currentTimeMillis( ); long diff = end - start; System.out.println("Difference is : " + diff); } catch (Exception e) { System.out.println("有一个例外!"); } } }
这将产生以下结果-
输出结果
Sun May 03 18:16:51 GMT 2009 Sun May 03 18:16:57 GMT 2009 Difference is : 5993
