java percentile calculation code example
Example 1: 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;
}
Example 2: 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];
