如何读取1行里面的多个数字到linkedlist?

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.text.DecimalFormat;
import java.util.LinkedList;
public class test {

public static void main(String[] args) {
LinkedList<Double> EstPrxSize = setLinkedList("EstPrxSize");
System.out.println("EstPrxSize: " + EstPrxSize);

}

public static LinkedList<Double> setLinkedList(String filename){

LinkedList<Double> temp = new LinkedList<Double>();

String path = System.getProperty("user.dir");
//path = path + "\\inputFile";
String inputfile = path + "\\" + filename +".txt";
String oneLine = "";
try{
BufferedReader reader = new BufferedReader(new FileReader(new File(inputfile)));
while(reader.ready()){
//temp.add(Double.parseDouble(oneLine));
oneLine = reader.readLine();
