例子

下面的示例演示java.io.FilterOutputStream.write(int b) 方法的用法。

package com.yiibai; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.FilterOutputStream; import java.io.IOException; import java.io.OutputStream; public class FilterOutputStreamDemo { public static void main(String[] args) throws Exception { OutputStream os = null; FilterOutputStream fos = null; FileInputStream fis = null; int i=0; char c; try{ // create output streams os = new FileOutputStream("C://test.txt"); fos = new FilterOutputStream(os); // writes buffer to the output stream fos.write(65); // forces byte contents to written out to the stream fos.flush(); // create input streams fis = new FileInputStream("C://test.txt"); // get byte from the file i = fis.read(); // convert integer to character c = (char)i; // print character System.out.print("Character read: "+c); }catch(IOException e){ // if any I/O error occurs System.out.print("Close() is invoked prior to write()"); }finally{ // releases any system resources associated with the stream if(os!=null) os.close(); if(fos!=null) fos.close(); } } }

讓我們編譯和運行上面的程序，這將產生以下結果：

Character read: A
