The write(char[], int, int) method of Writer Class in Java is used to write a specified portion of the specified character array on the writer. This character array is taken as a parameter. The starting index and length of characters to be written are also taken as parameters.

Syntax:

public void write(char[] charArray, int startingIndex, int lengthOfCharArray)

Parameters: This method accepts three mandatory parameters:

charArray which is the character array to be written in the writer.
startingIndex which is the starting index from which the portion of character is to taken.
lengthOfCharArray which is the length of characters to be written on the writer.

Return Value: This method do not returns any value.

Below methods illustrates the working of write(char[], int, int) method:

Program 1:

// Java program to demonstrate
// Writer write(char[], int, int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);
  
            // Get the character array
            // to be written in the writer
            char[] charArray = { 65, 66, 67 };
  
            // Get the starting index
            int startingIndex = 0;
  
            // Get the length of char
            int lengthOfCharArray = 1;
  
            // Write the portion of the charArray
            // to this writer using write() method
            // This will put the charArray in the writer
            // till it is printed on the console
            writer.write(charArray,
                         startingIndex,
                         lengthOfCharArray);
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

Program 2:

// Java program to demonstrate
// Writer write(char[], int, int) method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);
  
            // Get the character array
            // to be written in the writer
            char[] charArray = { 97, 98, 99 };
  
            // Get the starting index
            int startingIndex = 2;
  
            // Get the length of char
            int lengthOfCharArray = 1;
  
            // Write the portion of the charArray
            // to this writer using write() method
            // This will put the charArray in the writer
            // till it is printed on the console
            writer.write(charArray,
                         startingIndex,
                         lengthOfCharArray);
  
            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
