Question

我真的需要帮助Java io操作Streams。我不知道为什么这不会告诉我文件的内容。我需要能够在这个二进制文件中查看文本＆＃34; Data.abc＆＃34;如果我可以查看该文件的内容，我需要创建一个switch case条件来显示每行/每列的内容。每次我运行程序时，它会返回一些奇怪的字母和字符，如�NAme地址��

请帮忙。我对流的操纵很新。谢谢。

package IO_ReadFile;
import java.io.*;

public class ReadFile {

public static void main(String[] args) {

  InputStream istream;   // creates an Input Stream and named it "istream"
  OutputStream ostream;  // creates an Output Stream and named it "ostream"
  File inputFile = new File("Data.abc"); //passes file as argument
  int c;
  final int EOF=-1;
  ostream = System.out;
  try
  {
     istream = new FileInputStream(inputFile);
     try
     {
        while((c=istream.read()) !=EOF)
           ostream.write(c);
     }
     catch(IOException e)
     {
        System.out.println("Error: " + e.getMessage());
     }
     finally
     {
        try
        {
           istream.close();
           ostream.close();
        }
        catch(IOException e)
        {
        System.out.println("File did not close");
        }
     }
  }
  catch(FileNotFoundException e)
  {
     System.exit(1);
  }
}
}
