java io流之int数组数据的插入与取出

java io流大家都非常熟悉吧，有时候假设用的不熟，对于数据的处理真的非常头疼，以下是对与int数组的处理。

以下是代码：

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数组的处理是增加一个“，”隔开，然后用String的split()处理，希望对大家有所帮助。
