[844]How to sort an array using java.util.Arrays Sort???
By Anonymous on 2004/07/27 05:14:37 Rate
Hi,
I would like to know how to sort an array using java.util.Arrays Sort.
I have generate 100 random values for the array arr and I would like
to sort it. I have tried to sort it without success.
import cern.jet.random.AbstractDistribution;
import cern.jet.random.engine.RandomSeedGenerator;
import cern.jet.random.engine.MersenneTwister;
import cern.colt.Sorting;
import java.util.Arrays;
import javax.swing.*;
public class Gauss
{
public static void main ( String args [ ] )
{
Gauss div = new Gauss ( ) ;
}
public Gauss ( )
{
double [ ] arr= new double [ 100 ] ;
double cas;
double mean = 0;
double variance = 1;
cern.jet.random.engine.RandomEngine engine = new cern.jet.random.engine.MersenneTwister ( new java.util.Date ( ) ) ;
cern.jet.random.AbstractDistribution dist = new cern.jet.random.Normal ( mean,variance,engine ) ;
for ( int i=0; i < arr.length; i++ )
{
arr [ i ] =dist.nextDouble ( ) ;
}
}
}
I woul like to know how to sort the array arr using sort ( double [ ] )
Could someone suggest me the code?
Thank you very much for your help.
My best regards. gm

Hi everybody
I can view all values in arrays but need to merge it using collections.
Really appreciate any ideas.
