import java.io.*;
import java.util.Scanner;
public class FloatList
{ 
	public void getList(Scanner inFile) 
		throws IOException
	{
		float item;
		String data;
		while (inFile.hasNextFloat())
		{
			values[numItems] = inFile.nextFloat();
			numItems++;
		} 
	} 

	public void PrintList()
	{
		int index;

		for (index = 0; index < numItems; index++)
			System.out.println(values[index]);
	}

	public FloatList(int maxItems)
	{
		numItems = 0;
		values = new float[maxItems];
	}
	private int numItems;
	private float[] values;
}

import java.io.*;

import java.util.Scanner;
