Java reads local TXT documents

 

Create a fileinputstream stream mystream for the TXT file, create a bytearrayoutputstream my, and then read mystream and mystream. read (); then write data to my, my. write (); the written data is converted to the array type using tobytearray (). If the TXT document contains Chinese characters, you can use string (data, "gb2312") as the converted array type data ") decodes Chinese characters. Finally, output it to the screen!

Appendix:

Import java. Io .*;

Public class stream

{

Public static void main (string [] ARGs)

{

Try

{

String dirname = "D: // Java work // work zone ";

String myfile = "My java.txt ";

File afile = new file (dirname, myfile );

Inputstream r = new fileinputstream (afile );

Bytearrayoutputstream byteout = new bytearrayoutputstream ();

Byte TMP [] = new byte [256];

Byte context [];

Int I = 0;

While (I = R. Read (TMP ))! =-1)

{

Byteout. Write (TMP );

}

Context = byteout. tobytearray ();

String STR = new string (context, "gb2312"); // decodes Chinese Characters

// Separate rows

String stra [] = Str. Split ("\ n ");

For (INT n = 0; n <stra. length; n ++)

{

System. Out. println (stra [N]);

}

// System. Out. println (STR );

} Catch (exception E)

{

System. Out. println (E); // todo: handle exception

}

}

}

Input from the keyboard:

Code: bufferedreader BR = new bufferedreader (

New inputstreamreader (system. In ));

String myfile = (string) Br. Readline ();
