import org.apache.commons.math3.complex.Complex;
import org.apache.commons.math3.random.JDKRandomGenerator;

System.out.println(randomGenerator.nextInt());
System.out.println(randomGenerator.nextDouble());
/**
* Descriptive Statistics like MEAN,GP,SD,MAX
**/
DescriptiveStatistics stats = new DescriptiveStatistics();
stats.addValue(1);
stats.addValue(2);
stats.addValue(3);
stats.addValue(4);
stats.addValue(5);
stats.addValue(6);
stats.addValue(7);
System.out.print("Mean : "+stats.getMean()+"n");
System.out.print("Standard deviation : "+stats.getStandardDeviation()+"n");
System.out.print("Max : "+stats.getMax()+"n");
/**
* Complex number format a+bi
**/
Complex c1 = new Complex(1, 2);
Complex c2 = new Complex(2, 3);
System.out.print("Absolute of c1 "+c1.abs()+"n");
System.out.print("Addition : "+(c1.add(c2))+"n");
}
