ByteArrayInputStream available() method in Java with Examples

Last Updated : 13 Sep, 2021

The available() method is a built-in method of the Java.io.ByteArrayInputStream returns the number of remaining bytes that can be read (or skipped over) from this input stream. It tells the total no. of bytes from the Input Stream to be read.

Syntax:

public int available()

Parameters: The function does not accept any parameter.
Return Value: The function returns the total no of bytes from the Input Stream to be read.

Below is the implementation of the above function:

Program 1:

Java

// Java program to implement
// the above function
import java.io.*;
 
public class Main {
    public static void main(String[] args) throws Exception
    {
 
        // Array
        byte[] buffer = { 71, 69, 69, 75, 83 };
 
        // 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);
    }
}

Output:

Use of available() method : 5

Program 2:

Java

// 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);
    }
}

Output:

Use of available() method : 4
