以下示例显示java.io.BufferedOutputStream.write(int b)方法的用法。
package com.jc2182;
import java.io.BufferedOutputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class BufferedOutputStreamDemo {
public static void main(String[] args) throws Exception {
ByteArrayOutputStream baos = null;
BufferedOutputStream bos = null;
try {
// create new ByteArrayOutputStream
baos = new ByteArrayOutputStream();
// create new BufferedOutputStream with baos
bos = new BufferedOutputStream(baos);
// assign integer
int b = 87;
// write to stream
bos.write(b);
// force the byte to be written to baos
bos.flush();
// convert ByteArrayOutputStream to bytes
byte[] bytes = baos.toByteArray();
// prints the byte
System.out.println(bytes[0]);
} catch(IOException e) {
// if I/O error occurs.
e.printStackTrace();
} finally {
// releases any system resources associated with the stream
if(baos!=null)
baos.close();
if(bos!=null)
bos.close();
}
}
}
