ByteArrayOutputStream size() method in Java with Examples
The size() method of ByteArrayOutputStream class in Java is used to obtain the current size of the buffer. This buffer is accumulated inside the ByteArrayOutputStream. This method returns the size of the current buffer as an integer type.
Syntax:
public int size()
Parameters: This method does not accept any parameter.
Return value: This method returns the size of the current buffer as an integer.
Exceptions: This method does not throw any exception.
Below programs illustrate size() method in ByteArrayOutputStream class in IO package:
Program 1:
// Java program to illustrate // ByteArrayOutputStream size() method import java.io.*; public class GFG { public static void main(String[] args) throws Exception { // Create byteArrayOutputStream ByteArrayOutputStream byteArrayOutStr = new ByteArrayOutputStream(); // Create byte array byte[] buf = { 71, 69, 69, 75, 83 }; for (byte b : buf) { // Write byte // to byteArrayOutputStream byteArrayOutStr.write(b); // Print the byteArrayOutputStream // as String and size as integer System.out.println( byteArrayOutStr.toString() + " " + byteArrayOutStr.size()); } } } |

Program 2:
// Java program to illustrate // ByteArrayOutputStream size() method import java.io.*; public class GFG { public static void main(String[] args) throws Exception { // Create byteArrayOutputStream ByteArrayOutputStream byteArrayOutStr = new ByteArrayOutputStream(); // Create byte array byte[] buf = { 71, 69, 69, 75, 83, 70, 79, 82, 71, 69, 69, 75, 83 }; for (byte b : buf) { // Write byte // to byteArrayOutputStream byteArrayOutStr.write(b); // Convert byteArrayOutputStream // into String String s = byteArrayOutStr.toString(); int buffsize = byteArrayOutStr.size(); // Print string and size System.out.println( s + " " + buffsize); } } } |
