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前消耗的輸出,并將變量計數重置為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異常。

Example:
例:
// Java program to demonstrate the example
// of void reset() method of ByteArrayInputStream
import java.io.*;
public class ResetOfBAOS {
public static void main(String[] args) throws Exception {
byte b1 = 97;
byte b2 = 100;
ByteArrayOutputStream BAOS = null;
try {
// Instantiates ByteArrayOutputStream
BAOS = new ByteArrayOutputStream();
// By using write() method is to
// write b1 to the BAOS
BAOS.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 stream
BAOS.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
