用java创建文件number.txt, 里面存放多个整数。 2 读取该文件里面的数据,并统计平均值,最 大値,最小値。 3. 将统计的信息及数据排序后 写入result.txt 中。

好的，我可以为您提供相关的Java代码来实现这个功能。请注意，您需要在代码中指定number.txt文件和result.txt文件的完整路径。 ```java import java.io.*; import java.util.*; public class Main { public static void main(String[] args) { // 创建文件number.txt try { File file = new File("number.txt"); if (file.createNewFile()) { System.out.println("文件已创建"); } else { System.out.println("文件已存在"); } } catch (IOException e) { System.out.println("创建文件失败"); e.printStackTrace(); } // 写入数据到number.txt try { FileWriter writer = new FileWriter("number.txt"); writer.write("1 2 3 4 5 6 7 8 9 10"); writer.close(); } catch (IOException e) { System.out.println("写入文件失败"); e.printStackTrace(); } // 读取数据并统计平均值、最大值、最小值 try { FileReader reader = new FileReader("number.txt"); BufferedReader br = new BufferedReader(reader); String line; int sum = 0; int count = 0; int max = Integer.MIN_VALUE; int min = Integer.MAX_VALUE; while ((line = br.readLine()) != null) { String[] numbers = line.split(" "); for (String number : numbers) { int n = Integer.parseInt(number); sum += n; count++; max = Math.max(max, n); min = Math.min(min, n); } } double average = (double) sum / count; System.out.println("平均值：" + average); System.out.println("最大值：" + max); System.out.println("最小值：" + min); br.close(); reader.close(); } catch (IOException e) { System.out.println("读取文件失败"); e.printStackTrace(); } // 将统计信息及数据排序后写入result.txt try { FileReader reader = new FileReader("number.txt"); BufferedReader br = new BufferedReader(reader); String line; List<Integer> list = new ArrayList<>(); while ((line = br.readLine()) != null) { String[] numbers = line.split(" "); for (String number : numbers) { list.add(Integer.parseInt(number)); } } Collections.sort(list); FileWriter writer = new FileWriter("result.txt"); writer.write("平均值：" + String.format("%.2f", average) + "\n"); writer.write("最大值：" + max + "\n"); writer.write("最小值：" + min + "\n"); writer.write("排序后数据：\n"); for (int number : list) { writer.write(number + " "); } writer.close(); br.close(); reader.close(); } catch (IOException e) { System.out.println("读取或写入文件失败"); e.printStackTrace(); } } } ``` 此代码将会在当前目录下创建number.txt文件，并向其中写入数据1-10，然后从该文件中读取数据并计算平均值、最大值和最小值，最后将统计信息和排序后的数据写入result.txt文件中。
