Java Small Example: Reading text file contents by specified encoding

The InputStreamReader constructor provides a parameter that specifies what encoding is used to convert the read bytes to characters. Here is an example:

01./**
02. * Read the specified text file, and return to the content version. *
@param    path file. *
@param charset file code
07. * @return The contents
of the file
@throws ioexception If the file does not exist, open fails, or read failed
. */
11.private static String Readfi Le (string path, String charset) throws 

IOException {
.    String content = "";    BufferedReader reader = null;    try {
.        reader = new BufferedReader (new InputStreamReader (New 

FileInputStream (path), CharSet));
String line        ;
While        (line = Reader.readline ())!= null) {
.            Content + = line + "\ n";    finally {
.        } if (reader!= null)
.            try {
.                Reader.close ();
A            catch (IOException e) {
.                The exception that appears to turn off Reader is generally not handled.
Num            }
.    }
return    content;
30.}

PS: This is just an example of a inputstreamreader usage. Really hit the big file, how can all read into memory? The StringBuffer are all free.
