Pass static methods in Java Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of Pass static methods in Java without wasting too much if your time.

The question is published on by Tutorial Guruji team.

I am trying to create a class that times the average runtime of a method. I understand how to do that by running it 100 times and taking the average of it all. Example:

private long calculateAvg(){
    long totalTime = 0;

    for(int i = 0; i < ITERATIONS; i++){
        long startTime = System.nanoTime();
        long endTime = System.nanoTime();

        totalTime += (endTime - startTime);  //divide by 1000000 to get milliseconds.
    return (totalTime / ITERATIONS);


Now I can set this to work for one static method but is there a way to pass different static methods into this to calculate instead of creating one of these for each method I want to test? If not, is there a design pattern that may work here? As of now, I am creating one of these methods for every other method I want to time and it doesn’t seem efficient because I am reusing so much code.


You can accept and run a Runnable argument:

private long calculateAvg(Runnable r) {
    long startTime = System.nanoTime();;
    long endTime = System.nanoTime();

And call it like this:

long avg1 = calculateAvg(() -> testMethod());
long avg2 = calculateAvg(() -> testMethod2());
