ByteArrayOutputStream類reset()方法 (ByteArrayOutputStream Class reset() method)

• reset() method is available in java.io package.

  reset()方法在java.io包中可用。

• reset() method is used to reset this stream (i.e. it removes all currently consumed output in this stream and reset the variable count is set to 0).

  reset()方法用于重置此流(即，它將刪除此流中所有當(dāng)前消耗的輸出，并將變量計數(shù)重置為0)。

• reset() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  reset()方法是一種非靜態(tài)方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• reset() method does not throw an exception at the time of resetting the stream.

  reset()方法在重置流時不會引發(fā)異常。

Syntax:

句法：

public void reset();

Parameter(s):

參數(shù)：

• It does not accept any parameter.

  它不接受任何參數(shù)。

Return value:

返回值：

The return type of the method is void, it returns nothing.

該方法的返回類型為void ，不返回任何內(nèi)容。

Example:

例：

// Java program to demonstrate the example // of void reset() method of ByteArrayInputStreamimport java.io.*;public class ResetOfBAOS {public static void main(String[] args) throws Exception {byte b1 = 97;byte b2 = 100;ByteArrayOutputStream BAOS = null;try {// Instantiates ByteArrayOutputStreamBAOS = new ByteArrayOutputStream();// By using write() method is to// write b1 to the BAOSBAOS.write(b1);// By using toString() method is // to represent the b1 as a string// before using reset()System.out.println("BAOS.write(b1): " + BAOS.toString());// By using reset() method is// to reset the streamBAOS.reset();// By using write() method is to// write b2 to the BAOS BAOS.write(b2);// By using toString() method is // to represent the b2 as a string// after using reset()System.out.println("BAOS.write(b2): " + BAOS.toString());} catch (Exception ex) {System.out.println(ex.toString());} finally {if (BAOS != null)BAOS.close();}} }

Output

輸出量

BAOS.write(b1): a BAOS.write(b2): d
