What is the equivalent of this code to java?

I want to compute for the running time of this code using java but I have no idea how. Please help me out. TIA! #include<stdio.h> #include<time.h> int main(){ clock_t begin = clock(); int i; int n=50; int sum = 0; for( i = 0; i < n; ++i ) for( j = 0; j < n * n; ++j ) ++sum; clock_t end = clock(); double time_spent = (double)(end - begin) / CLOCKS_PER_SEC; printf("%f\n", time_spent); }

java c time convert runningtime

import java.util.concurrent.TimeUnit; public class Program { public static void main(String[] args) { long startTime = System.nanoTime(); int n = 50; int sum = 0; for(int i = 0; i < n; i++) { for(int j = 0; j < n * n; j++) { sum++; } } long endTime = System.nanoTime(); long duration = (endTime - startTime); long millis = TimeUnit.NANOSECONDS. toMillis(duration); System.out.println(millis); } }

♨️♨️ uhm, no. I'm talking about how to find the actual running time of a program through implementing the code

You are wanting this same code written in Java so you can compare the two CLOCKS_PER_Second to each other?
