percent in java code example

Example 1: calculating the percentile in java

for (i=0, sum=0; i<n; i++) sum += Number[i];
tot = sum;
for (i=0, sum=0; i<n && sum < 0.95*tot; i++) sum += Number[i];
// i is about it

Example 2: calculating the percentile in java

public static long[] percentiles(long[] latencies, double... percentiles) {
    Arrays.sort(latencies, 0, latencies.length);
    long[] values = new long[percentiles.length];
    for (int i = 0; i < percentiles.length; i++) {
      int index = (int) (percentiles[i] * latencies.length);
      values[i] = latencies[index];
    }
    return values;
  }
