The encoding that it uses may be specified by name, or the platform's default encoding may be accepted. <p> Each invocation of one of an InputStreamReader's read() methods may cause one or more bytes to be read from the underlying byte-input stream. To enable the efficient conversion of bytes to characters, more bytes may be read ahead from the underlying stream than are necessary to satisfy the current read operation. <p> For top efficiency, consider wrapping an InputStreamReader within a BufferedReader. For example: <pre> BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); </pre><P><DL><DT><B>Since: </B><DD>JDK1.1</DD><DT><B>See Also: </B><DD><A HREF="../../java/io/BufferedReader.html"><CODE>BufferedReader</CODE></A>, <A HREF="../../java/io/InputStream.html"><CODE>InputStream</CODE></A>, <a href="../lang/package-summary.html#charenc">Character encodings</a></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="fields_inherited_from_class_java.io.Reader"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class java.io.<A HREF="../../java/io/Reader.html">Reader</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/io/Reader.html#lock">lock</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#InputStreamReader(java.io.InputStream)">InputStreamReader</A></B>(<A HREF="../../java/io/InputStream.html">InputStream</A> in)</CODE><BR> Create an InputStreamReader that uses the default character encoding.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#InputStreamReader(java.io.InputStream, java.lang.String)">InputStreamReader</A></B>(<A HREF="../../java/io/InputStream.html">InputStream</A> in, <A HREF="../../java/lang/String.html">String</A> enc)</CODE><BR> Create an InputStreamReader that uses the named character encoding.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#close()">close</A></B>()</CODE><BR> Close the stream.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../java/lang/String.html">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#getEncoding()">getEncoding</A></B>()</CODE><BR> Returns the canonical name of the character encoding being used by this stream.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#read()">read</A></B>()</CODE><BR> Read a single character.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#read(char[], int, int)">read</A></B>(char[] cbuf, int off, int len)</CODE><BR> Read characters into a portion of an array.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../java/io/InputStreamReader.html#ready()">ready</A></B>()</CODE><BR> Tell whether this stream is ready to be read.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.io.Reader"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.io.<A HREF="../../java/io/Reader.html">Reader</A></B></TD>⌨️ 快捷键说明
