   sample as follow:
   ```
   
   import org.HdrHistogram.ConcurrentDoubleHistogram;
   import org.HdrHistogram.ConcurrentHistogram;
   
   public class HistogramExample {
       public static void main(String[] args) {
           // 创建 ConcurrentHistogram 对象
           ConcurrentDoubleHistogram histogram = new ConcurrentDoubleHistogram(2);
           // 向直方图中添加数据
           histogram.recordValue(1);  // 假设添加了多个值
           histogram.recordValue(2);  // 假设添加了多个值
           histogram.recordValue(3);  // 假设添加了多个值
           histogram.recordValue(4);  // 假设添加了多个值
           histogram.recordValue(5);  // 假设添加了多个值
           histogram.recordValue(6);  // 假设添加了多个值
           histogram.recordValue(7);  // 假设添加了多个值
           histogram.recordValue(8);  // 假设添加了多个值
           histogram.recordValue(9);  // 假设添加了多个值
           histogram.recordValue(10);  // 假设添加了多个值
   
           double valueAtPercentile = histogram.getValueAtPercentile(80.0);
           System.out.println(valueAtPercentile);
       }
   }
   ```
   result is：
   `8.0546875`
