存储为字符串：
public class ReadTemps { public static void main(String[] args) throws IOException { // TODO pre application logic here // // read KeyWestTemp.txt // create token1 String token1 = ""; // for-each loop for calculating heat index of May - October // create Scanner inFile1 Scanner inFile1 = new Scanner(new File("KeyWestTemp.txt")).useDelimiter(",\s*"); // Original answer used linkedList, but probably preferable to use ArrayList in most cases // List<String> temps = new linkedList<String>(); List<String> temps = new ArrayList<String>(); // while loop while (inFile1.hasNext()) { // find next line token1 = inFile1.next(); temps.add(token1); } inFile1.close(); String[] tempsArray = temps.toArray(new String[0]); for (String s : tempsArray) { System.out.println(s); } }}对于花车：
