C++ 获取函数耗时

C++ 记录耗时 

#include <sys/timeb.h>
#include <stdio.h>long long getSystemTime() {struct timeb t;ftime(&t);return 1000 * t.time + t.millitm;
}
{long long startTime = getSystemTime();long long endTime = getSystemTime();long long ticck = (endTime - startTime);__android_log_print(ANDROID_LOG_DEBUG, "wmh", "onSearchStatusChanged  S =%llu,E =%llu,ticck = %llu",startTime,endTime,ticck);
}

　　

Java 记录耗时

public class Time {public static void main(String[] args) {try {long startTime = System.currentTimeMillis();Thread.sleep(3000);long endTime = System.currentTimeMillis();System.out.println("time: " + (endTime - startTime) + " ms");} catch (InterruptedException e) {e.printStackTrace();}}
}
