PrintStream write(byte[], int, int) method in Java with Examples

Last Updated : 11 Jul, 2025
The write(byte[], int, int) method of PrintStream Class in Java is used to write a specified portion of the specified byteacter array on the stream. This byteacter array is taken as a parameter. The starting index and length of byteacters to be written are also taken as parameters. Syntax:
public void write(byte[] byteArray, int startingIndex, int lengthOfCharArray)
Parameters: This method accepts three mandatory parameters:
  • byteArray which is the byteacter array to be written in the Stream.
  • startingIndex which is the starting index from which the portion of byteacter is to taken.
  • lengthOfCharArray which is the length of byteacters to be written on the stream.
Return Value: This method do not returns any value. Below methods illustrates the working of write(byte[], int, int) method: Program 1: Java 
// Java program to demonstrate
// PrintStream write(byte[], int, int) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(System.out);

            // Get the byteacter array
            // to be written in the stream
            byte[] byteArray = { 65, 66, 67 };

            // Get the starting index
            int startingIndex = 0;

            // Get the length of byte
            int lengthOfCharArray = 1;

            // Write the portion of the byteArray
            // to this stream using write() method
            // This will put the byteArray in the stream
            // till it is printed on the console
            stream.write(byteArray,
                         startingIndex,
                         lengthOfCharArray);

            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output: 
A
Program 2: Java 
// Java program to demonstrate
// PrintStream write(byte[], int, int) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a PrintStream instance
            PrintStream stream
                = new PrintStream(System.out);

            // Get the byteacter array
            // to be written in the stream
            byte[] byteArray = { 97, 98, 99 };

            // Get the starting index
            int startingIndex = 2;

            // Get the length of byte
            int lengthOfCharArray = 1;

            // Write the portion of the byteArray
            // to this stream using write() method
            // This will put the byteArray in the stream
            // till it is printed on the console
            stream.write(byteArray,
                         startingIndex,
                         lengthOfCharArray);

            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
