HI,

Is there any tool available which would give me the time taken to execute a function and the rest of the functions that are called by the parent function in a recursive manner.
Presently I am writing system.out.println statement for each function and this is very time consuming.

thanks in advance.

Thanks

You can use System.currentTimeMillis() to get start and end times but you should collect many many data points.

Because of the granularity of system time, a single reading does not mean much.

Doing ANY System.out writes while timing will completely mess up the measurement. Collect the data, average and then print.
