The following example shows the usage of java.io.FilterOutputStream.Close() method.

package com.tutorialspoint;

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();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Close() is invoked prior to write()
