中文乱码解决方案：代码如下，请参照
public class TestStream {
public static void main(String[] args) throws Exception{
DataOutputStream dos = null; //声明数据输出流对象
File f = new File("D:" + File.separator + "order.txt");//指定文件的保存路径
OutputStreamWriter oStreamWriter = new OutputStreamWriter(new FileOutputStream(f), "utf-8");
dos = new DataOutputStream(new FileOutputStream(f));//实例化数据输出流对象
String names[] = {"衬衣","手套","围巾"};//商品名称
float prices[] = {98.3f,30.3f,50.5f}; //商品价格
int nums[] = {3,2,1}; //商品数量
for(int i = 0;i /*//循环写入
dos.writeChar(names[i]); //写入字符串
dos.writeChar('\t'); //加入分隔符
dos.writeFloat(prices[i]); //写入小数
dos.writeChar('\t'); //加入分隔符
dos.writeInt(nums[i]); //写入整数
dos.writeChar('\n'); //换行
*/
oStreamWriter.write(names[i]);
oStreamWriter.write('\t');
oStreamWriter.write(prices[i]+""); //写入小数
oStreamWriter.write('\t'); //加入分隔符
oStreamWriter.write(nums[i]); //写入整数
oStreamWriter.write('\n'); //换行
}
oStreamWriter.close(); //关闭输出流
}
