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
