measuring the execution time of a java method

[Jeremy Watts]

hi,

how would you measure the execution time of a java method?

how would you measure the execution time of a java method?

I guess you want to know how you could do it. You could e.g. run a
profiler, or use the difference of two calls to System.currentTimeMillis().

how would you measure the execution time of a java method?

long start = System.currentTimeMillis();
....
doSomething();
....
long end = System.currentTimeMillis();

System.out.println("Execution time was "+(end-start)+" ms.");
