Get rid of ugly if statements

Question

I have this ugly code:

if ( v > 10 ) size = 6; if ( v > 22 ) size = 5; if ( v > 51 ) size = 4; if ( v > 68 ) size = 3; if ( v > 117 ) size = 2; if ( v > 145 ) size = 1; return size; 

How can I get rid of the multiple if statements?

Answer 1

How about such approach:

int getSize(int v) {     int[] thresholds = {145, 117, 68, 51, 22, 10};      for (int i = 0; i < thresholds.length; i++) {         if (v > thresholds[i]) return i+1;     }     return 1; }

Functionally: (Demonstrated in Scala)

def getSize(v: Int): Int = {   val thresholds = Vector(145, 117, 68, 51, 22, 10)   thresholds.zipWithIndex.find(v > _._1).map(_._2).getOrElse(0) + 1 }
