java - Setting unique timers in for loop -

i using loop , setting timer @ beginning, , ending @ end. loop repeats 3 times , gives me 3 values need want able compare timer values gives me in java , compute results biggest-smallest. that, need each timer have unique name cannot seem do. here example of code.

int j; for(j=1;j<=3;++j){     //...code     {         long starttime = system.nanotime(); //timer start         //...code         long estimatedtime = system.nanotime() - starttime; //timer end         system.out.println(starttime + "_1");      }         {             timer comparison 3 timers         } 

as said, have values, need way compare them. "estimatedtime" value i'm comparing, ideally assign names "estimatedtime2" , "estimatedtime3" on second , third values.

you cannot declare variable different name "on fly", have save estimated time in array or other data structure (e.g., list) , index accordingly.

for example, do:

    long[] times = new long[3];      (int j=0;j<3;++j) {     //...code     {         long starttime = system.nanotime(); //timer start         //...code         times[j] = system.nanotime() - starttime; // times[0], times[1], times[2]         system.out.println(starttime + "_1");      }         {             // timer comparison 3 timers         }     } 

after loop completes execution, have 3 time estimations in times array.
