Can I pass a Method as parameter of another method in java?

Answer 1

Methods aren't first-class objects in Java, so they can't be passed as parameters. You could use wrap your method call in an annoymous class that extends e.g. the Runnable interface:

private void MeasureExecutionTime(Runnable r) {
    r.run();
}

...


MeasureExecutionTime(new Runnable() { public void run() { m(); } });
