ByteArrayInputStream close() method in Java with Examples

0 1 1 minute read

The close() method is a built-in method of the Java.io.ByteArrayInputStream closes the input stream and releases system resources associated with this stream to Garbage Collector.

Syntax:

public void close()

Parameters: The function does not accepts any parameter.

Return Value: The function returns nothing.

Below is the implementation of the above function:

Program 1:

// Java program to implement
// the above function
import java.io.*;
  
public class Main {
    public static void main(String[] args) throws Exception
    {
  
        // Array
        byte[] buffer = { 1, 2, 3, 4 };
  
        // Create InputStream
        ByteArrayInputStream geek
            = new ByteArrayInputStream(buffer);
  
        // Use the function to get the number
        // of available
        int number = geek.available();
  
        // Print
        System.out.println("Use of available() method : "
                           + number);
  
        // Closes the InputStream
        geek.close();
    }
}

Output:

Use of available() method : 4

Program 2:

// Java program to implement
// the above function
import java.io.*;
  
public class Main {
    public static void main(String[] args) throws Exception
    {
  
        // Array
        byte[] buffer = { 2, 3, 4, 8, 9 };
  
        // Create InputStream
        ByteArrayInputStream geek
            = new ByteArrayInputStream(buffer);
  
        // Use the function to get the number
        // of available
        int number = geek.available();
  
        // Print
        System.out.println("Use of available() method : "
                           + number);
  
        // Closes the InputStream
        geek.close();
    }
}
