I have added this so it reads the files one by one:

Get Set methods

Code:

package get.set; // packaged for reuse

 public class experiment
 {
 private double experiment1;
 private double experiment2;
 private double experiment3;

 // no-argument constructor calls other constructor with default values
 public experiment()
 {
 this ( 0.0, 0.0, 0.0 ); // call four-argument constructor
 } // end no-argument AccountRecord constructor

 // initialize a record
 public experiment( double exp1, double exp2, double exp3 )
 {
 setExperiment1( exp1 );
 setExperiment2( exp2 );
 setExperiment3( exp3 );
 } // end three-argument experiment constructor

 // set experiment1
 public void setExperiment1( double exp1 )
 {
 experiment1 = exp1;
 } // end method setExperiment1

 // get account number
 public double getExperiment1()
 {
 return experiment1;
 } // end method getExperiment1

 // set experiment2
 public void setExperiment2( double exp2 )
 {
 experiment2 = exp2;
 } // end method setExperiment2

 // get first name
 public double getExperiment2()
 {
 return experiment2;
 } // end method getExperiment2

 // set set experiment3
 public void setExperiment3( double exp3 )
 {
 experiment3 = exp3;
 } // end method setExperiment3

 // get experiment3
 public double getExperiment3()
 {
 return experiment3;
 } // end method getExperiment3
 } // end class experiment

Read file class

Code:

 import java.io.File;
 import java.io.FileNotFoundException;
 import java.lang.IllegalStateException;
 import java.util.NoSuchElementException;
 import java.util.Scanner;

 import get.set.experiment;

 public class readFile
 {
 private Scanner input;

 // enable user to open file
 public void openFile()
 {
 try
 {
 input = new Scanner( new File("Data_Set_1.txt") );
 } // end try
 catch ( FileNotFoundException fileNotFoundException )
 {
 System.err.println( "Error opening file." );
 System.exit( 1 );
 } // end catch
 } // end method openFile

 // read record from file
 public void readRecords()
 {
 // object to be written to screen
 experiment record = new experiment();

 System.out.printf( "%10s%15s%15s\n", "Experiment 1",
 " Experiment 2", " Experiment 3" );

 try // read records from file using Scanner object
 {
 while ( input.hasNext() )
 {
 record.setExperiment1(  input.nextDouble() ); // read experiment1
 record.setExperiment2(  input.nextDouble() ); // read experiment2
 record.setExperiment3(  input.nextDouble() ); // read experiment3


 // display record contents
 System.out.printf( "%10f%15f%15f\n",
 record.getExperiment1(), record.getExperiment2(),record.getExperiment3());
 } // end while
 } // end try
 catch ( NoSuchElementException elementException )
 {
 System.err.println( "File improperly formed." );
 input.close();
 System.exit( 1 );
 } // end catch
 catch ( IllegalStateException stateException )
 {
 System.err.println( "Error reading from file." );
 System.exit( 1 );
 } // end catch
 } // end method readRecords

 // close file and terminate application
 public void closeFile()
 {
 if ( input != null )
 input.close(); // close file
 } // end method closeFile
 } // end class readFile

Test Class

Code:

public class runReadFileTest
 {
 public static void main( String args[] )
 {
 readFile application = new readFile();

 application.openFile();
 application.readRecords();
 application.closeFile();
 } // end main
 } // end class runReadFileTest

Ok my next question is how to use algorithms from above to combine with these classes so they do waht they are suppose to do. Your help is greatly appreciated
