##info.blockchain.api.statistics package

The statistics package contains the Statistics class that reflects the functionality documented at at https://blockchain.info/api/charts_api. It makes various network statistics available, such as the total number of blocks in existence, next difficulty retarget block, total BTC mined in the past 24 hours etc.

Example usage:

package test;
import info.blockchain.api.statistics.*;

public class App 
{
    public static void main(String[] args) throws Exception
    {	
    	StatisticsResponse stats = Statistics.get();
    	
    	System.out.println(String.format("The current difficulty is %s. "
    			+ "The next retarget will happen in %s hours.",
    			stats.getDifficulty(), 
    			(stats.getNextRetarget() - stats.getTotalBlocks()) * stats.getMinutesBetweenBlocks() / 60));
    }
}
