Description

The java.io.ByteArrayInputStream.close() method releases any system resources associated with the stream . The methods in this class can be called after close() invocation without generating I/O error.

Declaration

Following is the declaration for java.io.ByteArrayInputStream.close() method:

public void close()

Parameters

  • NA

Return Value

This method doesn't return any value.

Exception

  • IOException

    -- -- If an I/O error occurs

Example

The following example shows the usage of java.io.ByteArrayInputStream.close() method.

package com.tutorialspoint;

import java.io.ByteArrayInputStream;
import java.io.IOException;

public class ByteArrayInputStreamDemo {
   public static void main(String[] args) throws IOException {
      
      byte[] buf = {65, 66, 67, 68, 69};
      ByteArrayInputStream bais = null;
      
      try{
         
         // create new byte array input stream
         bais = new ByteArrayInputStream(buf);
         
         // close invoked before read() and available() invocations
         bais.close();
         
         int count =0;
         
         // read till the end of the stream
         while((count = bais.available())>0)
         {
            
            // convert byte to character
            char c = (char)bais.read();
            
            // print number of bytes available
            System.out.print("available byte(s) : "+ count);
            
            // print characters read form the byte array
            System.out.println(" & byte read : "+c);
         }
      }catch(Exception e){
         // if I/O error occurs
         e.printStackTrace();
      }finally{
         if(bais!=null)
            bais.close();
      }
   }
}

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

available byte(s) : 5 & byte read : A
available byte(s) : 4 & byte read : B
available byte(s) : 3 & byte read : C
available byte(s) : 2 & byte read : D
available byte(s) : 1 & byte read : E
