java io流大家都很熟悉吧，有时候如果用的不熟，对于数据的处理真的很头疼，下面是对与int数组的处理。

下面是代码：

public class Stream {    private int a[];    private BufferedWriter bufferedWriter;    private BufferedReader bufferedReader;    private String pathName="e:\\stream.txt";private void random(){Random random=new Random(10000);a=new int[10000];for(int i=0;i<a.length;i++){a[i]=random.nextInt(10000);}}    private void write(){String write=intToString(a);try {bufferedWriter=new BufferedWriter(new FileWriter(pathName));bufferedWriter.write(write);bufferedWriter.close();} catch (IOException e) {e.printStackTrace();}}private void read(){try {bufferedReader=new BufferedReader(new FileReader(pathName));String read=bufferedReader.readLine();int[] array=stringToInt(read);for(int i=0;i<array.length;i++){System.out.println(array[i]);}} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}private String intToString(int[] a){StringBuilder stringBuilder=new StringBuilder();for(int i=0;i<a.length;i++){stringBuilder.append(a[i]).append(",");}stringBuilder.deleteCharAt(stringBuilder.length()-1);return stringBuilder.toString();}private int[] stringToInt(String str){String[] strAry = str.split(",");int[] ary=new int[strAry.length];for(int i=0;i<strAry.length;i++){ary[i]=Integer.parseInt(strAry[i]);}return ary;}public static void main(String[] args){        Stream stream =new Stream();        stream.random();        stream.write();        stream.read();    }}

这里对于int数组的处理是加入一个“，”隔开，然后用String的split()处理，希望对大家有所帮助。
