这是一个可能的解决方案的开始：
public static List<String> linesFromTo(int from, int to, String fileName) throws FileNotFoundException, IllegalArgumentException { return linesFromTo(from, to, fileName, "UTF-8");}public static List<String> linesFromTo(int from, int to, String fileName, String charsetName) throws FileNotFoundException, IllegalArgumentException { if(from > to) { throw new IllegalArgumentException("'from' > 'to'"); } if(from < 1 || to < 1) { throw new IllegalArgumentException("'from' or 'to' is negative"); } List<String> lines = new ArrayList<String>(); Scanner scan = new Scanner(new File(fileName), charsetName); int lineNumber = 0; while(scan.hasNextLine() && lineNumber < to) { lineNumber++; String line = scan.nextLine(); if(lineNumber < from) continue; lines.add(line); } if(lineNumber != to) { throw new IllegalArgumentException(fileName+" does not have "+to+" lines"); } return lines;}
