Program 1:

// Java program to demonstrate
// StringWriter append(char) method

import java.io.*;

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

        try {

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

            // Append the char value 'A'
            // to this writer using append() method
            // This will put the charValue in the
            // writer till it is appended on the console
            writer.append('A');

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

Output:

A

Program 2:

// Java program to demonstrate
// StringWriter append(char) method

import java.io.*;

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

        try {

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

            // Append the char value 'G'
            // to this writer using append() method
            // This will put the charValue in the
            // writer till it is appended on the console
            writer.append('G');

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