StringWriter write(String, int, int) method in Java with Examples

The write(String, int, int) method of StringWriter 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 does not returns any value.

Below programs illustrates the working of write(String, int, int) method:

Program 1:

// Java program to demonstrate
// StringWriter write(String, int, int) method

import java.io.*;

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

        try {

            // Create a StringWriter instance
            StringWriter writer
                = new StringWriter();

            // 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:

Program 2:

// Java program to demonstrate
// StringWriter write(String, int, int) method

import java.io.*;

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

        try {

            // Create a StringWriter instance
            StringWriter writer
                = new StringWriter();

            // 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);
        }
    }
}
