以下示例显示java.io.FilterOutputStream.Close()方法的用法。
package com.jc2182;
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;
try {
// create input streams
os = new FileOutputStream("C://test.txt");
fos = new FilterOutputStream(os);
// releases any system resources associated with the stream
fos.close();
// writes byte to the output stream
fos.write(65);
} 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-
Close() is invoked prior to write()
