Writer toString() method in Java with Examples

The toString() method of Writer Class in Java is used to get the String representation of this Writer instance. This method does not accepts any parameter and returns the required String value. 

Syntax:

public String toString()

Parameters: This method accepts does not accepts any parameter. 

Return Value: This method returns a String value which is the String representation of the Writer instance. 

Below methods illustrates the working of toString() method: 

Program 1:

Java

// Java program to demonstrate
// Writer toString() 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";

            // Write the string
            // to this writer using write() method
            writer.write(string);

            System.out.println("String representation: "
                               + writer.toString());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

String representation: java.io.PrintWriter@232204a1

Program 2:

Java

// Java program to demonstrate
// Writer toString() 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";

            // Write the string
            // to this writer using write() method
            writer.write(string);

            System.out.println("String representation: "
                               + writer.toString());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

String representation: java.io.PrintWriter@232204a1
