以下示例显示java.io.FilterOutputStream.write（byte [] b）方法的用法。
package com.jc2182;
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;
byte[] buffer = {65, 66, 67, 68, 69};
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(buffer);
// forces byte contents to written out to the stream
fos.flush();
// create input streams
fis = new FileInputStream("C://test.txt");
while((i = fis.read())!=-1) {
// converts integer to the character
c = (char)i;
// prints
System.out.println("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();
}
}
}
让我们编译并运行以上程序，这将产生以下结果-
Character read: A
Character read: B
Character read: C
Character read: D
Character read: E
