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

0 0 1 minute read

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 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:

Program 2:

// 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);
        }
    }
}
