The append(char) method of CharArrayWriter class in Java is used to append the specified character to the writer. This append() method appends one character at a time to the CharArrayWriter and returns this CharArrayWriter. Syntax:

```java // Java program to illustrate // CharArrayWriter append(char) method
import java.io.*;
public class GFG { public static void main(String[] args) {
// Create charArrayWriter CharArrayWriter charArrayWriter = new CharArrayWriter();
// Append the character charArrayWriter.append('G');
charArrayWriter.append('E');
