is there already a cleaner way to count active lines of code in a function ? this works but it is kinda crude
but it works ! with this the efficiency of a function can be measured
tbh ngl tbpqh tbhngl ngltbh

You might want to look at this: https://docs.microsoft.com/en-us/visualstudio/code-quality/code-metrics-values?view=vs-2019

Visual Studio does work with other languages other than .NET supported languages. But there is a listing on that page that could direct you to other types of metrics for code.

I am puzzled about the practical use of activated code lines as a measure of efficiency. Normally I would tally clock ticks per second if I wanted to know if a function needs optimising. A code line could contain anything from a value assignment to a function call in a loop, so there can be quite a bit of difference in their execution times.

that is the thing I didn't find other ways to do it.

I see. I'm not very familiar with Java, but some of the functions here look promising:
https://www.tutorialspoint.com/javatime/javatime_clock.htm

In C++, you'd call a clock() function at the start of the function, another one at the end, and compare the difference, like a stopwatch. Or more commonly you start a clock first, then run your function 1000x, then check the difference.

What would work a bit better, and perhaps this is what you implied, set up a test rig or harness that links or references the function library(s) that you want to test, and before you call each function start a stopwatch like timer.  Collect the results and store them in a file or just output to a console or UI window.

Code

package chobit;

import java.util.Calendar;
import java.util.Date;

public class TimeGate {
	// a gate that only opens x minutes after it has been set
	private int pause = 1;
	private Date openedGate = addMinutesToJavaUtilDate(new Date(), pause);
	private Date checkPoint = new Date();
	public TimeGate(int minutes) {
		super();
		this.pause = minutes;
	}
	public TimeGate() {
	}
	public Boolean isClosed() {
		return !openedGate.before(new Date());
	}
	public void close() {
		this.openedGate = addMinutesToJavaUtilDate(new Date(), pause);
	}
	public void close(int minutes) {
		Date now = new Date();
		openedGate = addMinutesToJavaUtilDate(now, minutes);
	}
	private Date addMinutesToJavaUtilDate(Date date, int minutes) {
	    Calendar calendar = Calendar.getInstance();
	    calendar.setTime(date);
	    calendar.add(Calendar.MINUTE, minutes);
	    return calendar.getTime();
	}
	public void setPause(int pause) {
		if(pause <60 && pause >0) {
		this.pause = pause;}
	}

	public void resetCheckPoint() {
		this.checkPoint = new Date();
	}

	public int givenTwoDateTimesInJava8_whenDifferentiatingInSeconds_thenWeGetTen() {
		Date now = new Date();
		long diff = now.getTime() - this.checkPoint.getTime();
		long diffSeconds = diff / 1000 % 60;
		// long diffMinutes = diff / (60 * 1000) % 60;
		// long diffHours = diff / (60 * 60 * 1000) % 24;
		// long diffDays = diff / (24 * 60 * 60 * 1000);
		// System.out.print(diffDays + " days, ");
		// System.out.print(diffHours + " hours, ");
		// System.out.print(diffMinutes + " minutes, ");
		// System.out.print(diffSeconds + " seconds.");
		return (int) diffSeconds;
	}
}

use example:

Code

TimeGate timeGate = new TimeGate();
		timeGate.resetCheckPoint();
		for (int i = 0; i < 10000000; i++) {
			System.out.println("");
		}
		System.out.println(timeGate.givenTwoDateTimesInJava8_whenDifferentiatingInSeconds_thenWeGetTen());
