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 functionimport 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 functionimport 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();    }} |
Output:
Use of available() method : 5
