Thanks rjuyal

@OP, Just a quick....

When optimizing such code,
The fastest loop that i've ever read is the while loop that compares the value to zero. second is the boolean.

while( something != 0){ ... }

while( true ){ ... }

Any other process that can just initialize once, put them away from the loop.

Code:

while( something != 0){
      Double d = value / ( 3 + 2 * 3);
      Something executes
}

instead,

Code:

Double d;
Double t1 = 9.0  ( MDAS rule )
while( something != 0){
      d = value / t1;
      Something executes
}

My example really too far from the given codes, but you can get some ideas... ( i hope )
