Explanation / Answer

//Hope this will help you, I havecompiled the code below. You should have CramsterA3Q1 classwith static function getIntFromInterval
public class CramsterA4Q1 {    // open public class      public static void main (String [] args )    { // open main method    double highest= 0 ;    double lowest= 10;      int arraySize = CramsterA3Q1.getIntFromInterval("Enter thesize of the array",100,0);      double maxRandomNumbers=CramsterA3Q1.getIntFromInterval("Enter themax value of random numbers",10,0);      double [] histogram = new double [arraySize];      for (int i=0 ;i<histogram.length;i++)      histogram [i]= Math.round((Math.random()*maxRandomNumbers+1)*10)/10.0;    for (inti=0;i<histogram.length;i++){    if (histogram[i]>highest)      highest = histogram[i];    if (histogram[i]<lowest)    lowest= histogram[i]; } for(int i=0;i<histogram.length;i++){      System.out.println(histogram[i]); } System.out.println(highest); System.out.println(lowest); double range=highest-lowest; int numberOfBins; for ( inti=0;i<histogram.length;i++) { numberOfBins =CramsterA3Q1.getIntFromInterval("Enter the number ofbins",40,2); intmaxBinNumber=numberOfBins-1; int binIndex=(int)Math.min((histogram[i] -lowest)/range * numberOfBins,maxBinNumber); int [] bins = new int[numberOfBins]; } } }
