Parameters: This method accepts a mandatory parameter charSequence which is the CharSequence to be written in the writer.
Return Value: This method returns this StringWriter instance.
Below programs illustrates the working of append(CharSequence) method:
Program 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); } }} |
Output:
GeeksForGeeks
Program 2:
// 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 '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) { System.out.println(e); } }} |
