以下示例程序旨在说明append(CharSequence)方法的用法：

示例1:

// Java program to demonstrate 
// StringWriter append(CharSequence) method 
  
import java.io.*; 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        try { 
  
            // Create a StringWriter instance 
            StringWriter writer 
                = new StringWriter(); 
  
            // Write the CharSequence 'GeeksForGeeks' 
            // to this writer using append() method 
            // This will put the charSequence in the writer 
            // till it is printed on the console 
            writer.append("GeeksForGeeks"); 
  
            System.out.println(writer.toString()); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：

GeeksForGeeks

        try { 
  
            // Create a StringWriter instance 
            StringWriter writer 
                = new StringWriter(); 
  
            // Write the CharSequence 'GFG' 
            // to this writer using append() method 
            // This will put the charSequence in the writer 
            // till it is printed on the console 
            writer.append("GFG"); 
  
            writer.flush(); 
        } 
        catch (Exception e) {
