The write(String, int, int) method of Writer Class in Java is used to write a specified portion of the specified String on the stream. This String is taken as a parameter. The starting index and length of String to be written are also taken as parameters.
Syntax:

public void write(String string, int startingIndex, int lengthOfstring)

Parameters: This method accepts three mandatory parameters:

string which is the String to be written in the Stream.
startingIndex which is the starting index from which the portion of character is to taken.
lengthOfstring which is the length of String to be written on the stream.

Return Value: This method do not returns any value. Below methods illustrates the working of write(String, int, int) method: Program 1:

Java

// Java program to demonstrate
// Writer write(String, 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 String
            // to be written in the stream
            String string = "GeeksForGeeks";

            // Get the starting index
            int startingIndex = 0;

            // Get the length of char
            int lengthOfstring = 5;

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

            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

Geeks

Program 2:

Java

// Java program to demonstrate
// Writer write(String, 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 String
            // to be written in the stream
            String string = "GFG";

            // Get the starting index
            int startingIndex = 2;

            // Get the length of char
            int lengthOfstring = 1;

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

            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
